This issue has cropped up many times here on DevForums. Someone recently opened a DTS tech support incident about it, and I used that as an opportunity to post a definitive response here. If you have questions or comments about this, start a new thread and tag it with Network so that I see it. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" iOS Network ****** Strength The iOS SDK has no general-purpose API that returns Wi-Fi or cellular ****** strength in real time. Given that this has been the case for more than 10 years, it’s safe to assume that it’s not an accidental omission but a deliberate design choice. For information about the Wi-Fi APIs that are available on iOS, see TN3111 iOS Wi-Fi API overview. Network performance Most folks who ask about this are trying to use the ****** strength to estimate network performance. This is a technique that I specifically recommend against. That’s because it produces both false positives and false negatives: The network ****** might be weak and yet your app has excellent connectivity. For example, an iOS device on stage at WWDC might have terrible WWAN and Wi-Fi ****** but that doesn’t matter because it’s connected to the Ethernet. The network ****** might be strong and yet your app has very poor connectivity. For example, if you’re on a train, Wi-Fi ****** might be strong in each carriage but the overall connection to the Internet is poor because it’s provided by a single over-stretched WWAN. The only good way to determine whether connectivity is good is to run a network request and see how it performs. If you’re issuing a lot of requests, use the performance of those requests to build a running estimate of how well the network is doing. Indeed, Apple practices what we preach here: This is exactly how HTTP Live Streaming works. Remember that network performance can change from moment to moment. The user’s train might enter or leave a tunnel, the user might step into a lift, and so on. If you build code to estimate the network performance, make sure it reacts to such changes. Keeping all of the above in mind, iOS 26 beta has two new APIs related to this issue: Network framework now offers a linkQuality property. See this post for my take on how to use this effectively. The WirelessInsights framework can notify you of anticipated WWAN condition changes. But what about this code I found on the ’net? Over the years various folks have used various unsupported techniques to get around this limitation. If you find code on the ’net that, say, uses KVC to read undocumented properties, or grovels through system logs, or walks the view hierarchy of the status bar, don’t use it. Such techniques are unsupported and, assuming they haven’t broken yet, are likely to break in the future. But what about Hotspot Helper? Hotspot Helper does have an API to read Wi-Fi ****** strength, namely, the signalStrength property. However, this is not a general-purpose API. Like the rest of Hotspot Helper, this is tied to the specific use case for which it was designed. This value only updates in real time for networks that your hotspot helper is managing, as indicated by the isChosenHelper property. But what about MetricKit? MetricKit is so cool. Amongst other things, it supports the MXCellularConditionMetric payload, which holds a summary of the cellular conditions while your app was running. However, this is not a real-time ****** strength value. But what if I’m working for a carrier? This post is about APIs in the iOS SDK. If you’re working for a carrier, discuss your requirements with your carrier’s contact at Apple. Revision History 2025-07-02 Updated to cover new features in the iOS 16 beta. Made other minor editorial changes. 2022-12-01 First posted.

I have a watchOS app with a connected iOS app using Swift and SwiftUI. The watchOS app should read heart rate date in the background using HKOberserQuery and enableBackgroundDelivery(), send the data to the iPhone app via WCSession. The iPhone app then sends the data to a Firebase project. The issue I am facing now it that the app with the HKObserverQuery works fine when the app is in the foreground, but when the app runs in the background, the observer query gets triggered for the first time (after one hour), but then always get terminated from the watchdog timeout with the following error message: CSLHandleBackgroundHealthKitQueryAction scene-create watchdog transgression: app<app.nanacare.nanacare.nanaCareHealthSync.watchkitapp((null))>:14451 exhausted real (wall clock) time allowance of 15.00 seconds I am using Xcode 16.3 on MacOS 15.4 The App is running on iOS 18.4 and watchOS 11.4 What is the reason for this this issue? I only do a simple SampleQuery to fetch the latest heart rate data inside the HKObserverQuery and then call the completionHandler. The query itself takes less than one second. Or is there a better approach to read continuously heart rate data from healthKit in the background on watchOS? I don't have an active workout session, and I don't need all heart rate data. Once every 15 minutes or so would be enough.

I'm working with the Screen Time API (FamilyActivityPicker) in SwiftUI and need help with a specific scenario. I'm using the FamilyActivityPicker to let users select apps and categories to block. I save the previous selection (both applicationTokens and categoryTokens) locally. When the user updates their selection, I compare the new selection with the saved one to determine which apps or categories were removed. However, I’m trying to handle a specific case: when an individual app token is removed from the selection because its entire category was selected instead. In this situation, even though the app is no longer in applicationTokens, it's still blocked due to its category being included in categoryTokens. Since I need to show users which apps were actually removed, I want to avoid listing apps that are still indirectly blocked via a selected category. I’ve created a mapping between ApplicationToken and FamilyActivityCategoryToken to check whether a removed app is still covered by a selected category before displaying it. Is there any way to check this using the current Screen Time APIs, or does the system not give access to the relationship between apps and their categories? Any help or suggestions would mean a lot!

We are testing our existing live build, which was prepared with Xcode 16.2, on iOS 26 beta for experience assurance and found that the [[UIDevice currentDevice] systemVersion] API is returning iOS 19 instead of the expected version iOS 26. Has anyone else observed this issue?

We've been developing an iOS app in Swift for several years that run on iPad tablets in which our proprietary device emits EEG signals via BLE to the app running on the iPad tablet. The device emits the data as BLE notification messages in which the MTU is set to the maximum size that is allowed between our device and the iPad. Our device when communicating with the app running on a 10th generation iPad running iOS 18.5 it takes less than 200ms to transmit an interval of EEG signals which occurs at 500ms. Under the same conditions same version of iOS & app and the same device but using an iPad 11th generation, it takes anywhere from 800ms to 1.1 seconds (4x to 5x) to transmit an interval. Our device transmits the EEG ****** using several ATT notification messages using the maximum MTU size. We are perplexed about such a huge step down in performance when running on the iPad 11th generation tablets. iPad generation Chipset Firmware -------------------------------------------------------------- 10th BCM_4387 22.5.614.3457 11th SRS_7923 HCI Rev. 2504 sub. 5003 We know that the 10th generation iPad used chipset manufactured by Broadcom. Whereas the iPad 11th generation that we've received uses a SRS chipset in which I'm unfamiliar with that chipset's manufacturer. We question if this performance degradation is due from the chipset manufacturer, the firmware revision when using attribute notifications messages over BLE in such a context. Using PacketLogger as to log the communication between the iPad tablets and our device and after analysis we haven't found anything that identifies difference in configuration settings that are exchanged between our device and iPad tablets that account for this performance degradation. Fortunately, our device is designed to work in complex environments & contexts and thus it has mechanisms accounting for transmission delays and interferences. I'd appreciate if any other Apple Developer or Apple staff is aware of the degradation when transmitting BLE attribute notification messages with the newer Apple devices using this series of chipset. If so, then: Are there any recommendations of solutions to improve this latency? Is this is being addressed for iPad 11th generation tablets?

Hi Everyone. I wanna run the live activity in terminated state. I have implemented the push notification flow which is working fine in foreground and background state. In the terminated state, the push to start token is not getting generated. How to make it work?

I haven’t been able to get this to work at any level! I’m running into multiple issues, any light shed on any of these would be nice: I can’t implement a bloom filter that produces the same output as can be found in the SimpleURLFilter sample project, after following the textual description of it that’s available in the documentation. No clue what my implementation is doing wrong, and because of the nature of hashing, there is no way to know. Specifically: The web is full of implementations of FNV-1a and MurmurHash3, and they all produce different hashes for the same input. Can we get the proper hashes for some sample strings, so we know which is the “correct” one? Similarly, different implementations use different encodings for the strings to hash. Which should we use here? The formulas for numberOfBits and numberOfHashes give Doubles and assign them to Ints. It seems we should do this conversing by rounding them, is this correct? Can we get a sample correct value for the combined hash, so we can verify our implementations against it? Or ignoring all of the above, can we have the actual code instead of a textual description of it? 😓 I managed to get Settings to register my first attempt at this extension in beta 1. Now, in beta 2, any other project (including the sample code) will redirect to Settings, show the Allow/Deny message box, I tap Allow, and then nothing happens. This must be a bug, right? Whenever I try to enable the only extension that Settings accepted (by setting its isEnabled to true), its status goes to .stopped and the error is, of course, .unknown. How do I debug this? While the extension is .stopped, ALL URL LOADS are blocked on the device. Is this to be expected? (shouldFailClosed is set to false) Is there any way to manually reload the bloom filter? My app ships blocklist updates with background push, so it would be wasteful to fetch the filter at a fixed interval. If so, can we opt out of the periodic fetch altogether? I initially believed the API to be near useless because I didn’t know of its “fuzzy matching” capabilities, which I’ve discovered by accident in a forum post. It’d be nice if those were documented somewhere! Thanks!!

Is there an App Store Server API available that allows cancellation of specific subscriptions by specifying transaction_id or similar identifiers? Background of these questions: We occasionally suspend user accounts due to violations of our service terms and conditions. In such cases, we would like to forcibly cancel their subscriptions if possible. However, we could not find relevant information in the documentation, which is why we are reaching out with these questions. Please let us know.

(related post: How to optimize my app for for a carrier-provided satellite network? ) I am trying to implement an app so that it works under a carrier-provided satellite network. The app uses (AS)WebAuthenticationSession for signing in. If the app is entitled to access a satellite network, will (AS)WebAuthenticationSession work as well? How about WKWebView and SFSafariViewController? Is there a way to test(simulate) a ultra-constrained network on a device or a simulator to see the expected behavior? Thanks,

Is There a Reliable Way to Check Local Network Permission Status in 2025? I've read many similar requests, but I'm posting this in 2025 to ask: Is there any official or reliable method to check the current Local Network permission status on iOS 18.x? We need this to guide or navigate users to the appropriate Settings page when permission is denied. Background Our app is an IoT companion app, and Local Network access is core to our product's functionality. Without this permission, our app cannot communicate with the IoT hardware. Sadly, Apple doesn't provide any official API to check the current status of this permission. This limitation has caused confusion for many users, and we frequently receive bug reports simply because users have accidentally denied the permission and the app can no longer function as expected. Our App High Level Flow: 1. Trigger Permission We attempt to trigger the Local Network permission using Bonjour discovery and browsing methods. (see the implementation) Since there's no direct API to request this permission, we understand that iOS will automatically prompt the user when the app makes its first actual attempt to communicate with a local network device. However, in our case, this creates a problem: The permission prompt appears only at the time of the first real connection attempt (e.g., when sending an HTTP request to the IoT device). This results in a poor user experience, as the request begins before the permission is granted. The first request fails silently in the background while the permission popup appears unexpectedly. We cannot wait for the user's response to proceed, which leads to unreliable behavior and confusing flows. To avoid this issue, we trigger the Local Network permission proactively using Bonjour-based discovery methods. This ensures that the system permission prompt appears before any critical communication with the IoT device occurs. We’ve tried alternative approaches like sending dummy requests, but they were not reliable or consistent across devices or iOS versions. (see the support ticket) 2. Wi-Fi Connection: Once permission is granted, we allow the user to connect to the IoT device’s local Wi-Fi. 3. IoT Device Configuration: After connecting, we send an HTTP request to a known static IP (e.g., 192.168.4.1) on the IoT network to configure the hardware. I assume this pattern is common among all Wi-Fi-based IoT devices and apps. Problem: Even though we present clear app-level instructions when the system prompt appears, some users accidentally deny the Local Network permission. In those cases, there’s no API to check if the permission was denied, so: We can’t display a helpful message. We can’t guide the user to Settings → Privacy &amp; Security → Local Network to re-enable it. The app fails silently or behaves unpredictably. Developer Needs: As app developers, we want to handle negative cases gracefully by: Detecting if the Local Network permission was denied Showing a relevant message or a prompt to go to Settings Preventing silent failures and improving UX So the question is: What is the current, official, or recommended way to determine whether Local Network permission is granted or denied in iOS 18.x (as of 2025)? This permission is critical for a huge category of apps especially IoT and local communication-based products. We hope Apple will offer a better developer experience around this soon. Thanks in advance to anyone who can share updated guidance.

Hi everyone, I’m working on an iOS project where an iPhone needs to connect to external scanners (dedicated hardware devices) over Wi-Fi. The goal is to: Discover available Wi-Fi networks from the scanner devices (broadcasting their own networks). Allow the user to seamlessly connect to the chosen scanner network. Network Discovery: Is there a way to programmatically list available Wi-Fi networks (SSIDs) on iOS without private APIs? If not, are there workarounds (e.g., Bonjour/mDNS)? Seamless Connection: As I see, we can use NEHotspotConfigurationManager to connect to and disconnect from specified networks and there will always be a system alert asking about do we really want to join this network Hardware/Firmware/Software Alternatives: If iOS restrictions prevent this, what alternatives exist? For example: Hardware: Scanners supporting Bluetooth LE for initial pairing, then Wi-Fi provisioning. Firmware: Scanners acting as clients on the same network as the iPhone (e.g., via user’s home/office Wi-Fi). Software: A companion app for the scanner that shares network credentials via QR code/NFC, or a local web server on the scanner for setup. Context: Target: iOS 16+ No jailbreaking; App Store compliance is a must. Scanners can be configured to act as APs or clients.

Some paid users are unable to use the paid features unlocked by purchasing our subscription plan. It seems that this is due to StoreKit 2's Transaction.currentEntitlements not working the way we would expect it to work. Are you also encountering this issue? Do you have any idea to improve this situation? At launch, our app checks if the user is subscribed to the plan, using Transaction.currentEntitlements. As a result, the currentEntitlements array was empty. Our app then fetches the products from StoreKit 2 using Product.products(for:). As a result, the Product.SubscriptionInfo.RenewalState value of the corresponding Product (product.subscription.status.first.state) is subscribed, which confirms that the user has indeed purchased our plan, but seems to contradict the absence of the corresponding transaction in Transaction.currentEntitlements. Proactive in-app purchase restore and a restore purchase button calling the AppStore.sync() method are implemented, but using the button did not solve the issue.

On an app that was using the old API for In-App Purchases (StoreKit 1). The app is already published on the App Store. The purchase is non-consumable. While trying to migrate to StoreKit 2, I'm unable to restore purchases. Specifically displaying and purchasing products works as expected, but when deleting and reinstalling the app, and then trying to restore purchases I can't do it. I'm trying to restore them using the new APIs but it doesn't seem to be working. What I have tried so far: I'm listening for transaction updates during the whole lifetime of the app, with: Task.detached { for await result in Transaction.updates { if case let .verified(safe) = result { } } } I have a button that calls this method, but other than prompting to log in again with the Apple ID it doesn't seem to have any effect at all: try? await AppStore.sync() This doesn't return any item for await result in Transaction.currentEntitlements { if case let .verified(transaction) = result { } } This doesn't return any item for await result in Transaction.all { if case let .verified(transaction) = result { } } As mentioned before I'm trying this after purchasing the item and deleting the app. So I'm sure it should be able to restore the purchase. Am trying this both with a Configuration.storekit file on the simulator, and without it on a real device, in the Sandbox Environment. Has anyone being able to restore purchases using StoreKit 2? PD: I already filed a feedback report on Feedback Assistant, but so far the only thing that they have replied is: Because StoreKit Testing in Xcode is a local environment, and the data is tied to the app, when you delete the app you're also deleting all the transaction data for that app in the Xcode environment. The code snippets provided are correct usage of the API. So yes, using a Configuration.storekit file won't work on restoring purchases, but if I can't restore them on the Sandbox Environment I'm afraid that this won't work once released, leaving my users totally unable to restore what they have already purchased.

Im having trouble enabling Live Activities in a new app. The option is not available in Xcode or in the developer portal. Is there something I have to do to activate this option?

I have an AppIntent that edits an object in my app. The intent accepts an app entity as a parameter, so if you run the intent it will ask which one do you want to edit, then you select one from the list and it shows a dialog that it was edited successfully. I use this same intent in my Home Screen widget initializing it with an objectEntity. The code needs to run in the app's process, not the widget extension process, so the file is added to both targets and it conforms to ForegroundContinuableIntent, and that is supposed to ensure it always runs in the app process. This works great when run from the Shortcuts app and when involved via a button in the Home Screen widget, exactly as expected. Here is that app intent: @available(iOS 17.0, *) struct EditObjectIntent: AppIntent { static let title: LocalizedStringResource = "Edit Object" @Parameter(title: "Object", requestValueDialog: "Which object do you want to edit?", inputConnectionBehavior: .connectToPreviousIntentResult) var objectEntity: ObjectEntity init() { print("INIT") } init(objectEntity: ObjectEntity) { self.objectEntity = objectEntity } @MainActor func perform() async throws -> some IntentResult & ReturnsValue<ObjectEntity> & ProvidesDialog { // Edit the object from objectEntity.id... return .result(value: objectEntity, dialog: "Done") } } @available(iOS 17.0, *) @available(iOSApplicationExtension, unavailable) extension EditObjectIntent: ForegroundContinuableIntent { } I now want to create a ControlButton that uses this intent: struct EditObjectControlWidget: ControlWidget { var body: some ControlWidgetConfiguration { StaticControlConfiguration(kind: "EditObjectControlWidget") { ControlWidgetButton(action: EditObjectIntent()) { Label("Edit Object", systemImage: "pencil") } } } } When I add the button to Control Center and tap it (on iOS 18), init is called 3x in the app process and 2x in the widget process, yet the perform function is not invoked in either process. No error appears in console logs for the app's process, but this appears for the widget process: LaunchServices: store <private> or url <private> was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=72, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} Attempt to map database failed: permission was denied. This attempt will not be retried. Failed to initialize client context with error Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=72, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} What am I doing wrong here? Thanks!

I'm creating an App that can accepted PDFs from a shared context. I am using iOS, Swift, and UIKit with IOS 17.1+ The logic is: get the context see who is sending in (this is always unknown) see if I can open in place (in case I want to save later) send the URL off to open the (PDF) document and load it into PDFKit's pdfView.document I have no trouble loading PDF docs with the file picker. And everything works as expected for shares from apps like Messages, email, etc... (in which case URLContexts.first.options.openInPlace == False) The problem is with opening (sharing) a PDF that is sent from the Files App. (openInPlace == True) If the PDF is in the App's Document Folder, I need the Security scoped resource, to access the URL from the File's App so that I can copy the PDF's data to the PDFViewer.document. I get Security scoped resource access granted each time I get the File App's context URL. But, when I call fileCoordinator.coordinate and try to access a file outside of the App's document folder using the newUrl, I get an error. FYI - The newUrl (byAccessor) and context url (readingItemAt) paths are always same for the Files App URL share context. I can, however, copy the file to a new location in my apps directory and then open it from there and load in the data. But I really do not want to do that. . . . . . Questions: Am I missing something in my pList or are there other parameters specific to sharing a file from the Files App? I'd appreciate if someone shed some light on this? . . . . . Here are the parts of my code related to this with some print statements... . . . . . SceneDelegate func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) { // nothing to see here, move along guard let urlContext = URLContexts.first else { print("No URLContext found") return } // let's get the URL (it will be a PDF) let url = urlContext.url let openInPlace = urlContext.options.openInPlace let bundleID = urlContext.options.sourceApplication print("Triggered with URL: \(url)") print("Can Open In Place?: \(openInPlace)") print("For Bundle ID: \(bundleID ?? "None")") // get my Root ViewController from window if let rootViewController = self.window?.rootViewController { // currently using just the view if let targetViewController = rootViewController as? ViewController { targetViewController.prepareToLoadSharedPDFDocument(at: url) } // I might use a UINavigationController in the future else if let navigationController = rootViewController as? UINavigationController, let targetViewController = navigationController.viewControllers.first as? ViewController { targetViewController.prepareToLoadSharedPDFDocument(at: url) } } } . . . . ViewController function I broke out the if statement for accessingScope just to make it easier for me the debug and play around with the code in accessingScope == True func loadPDF(fromUrl url: URL) { // If using the File Picker / don't use this // If going through a Share.... we pass the URL and have three outcomes (1, 2a, 2b) // 1.

Other relevant pList settings I've added are: Supports opening documents in place - YES Document types - PDFs (com.adobe.pdf) UIDocumentBrowserRecentDocumentContentTypes - com.adobe.pdf Application supports iTunes file sharing - YES And iCloud is one for Entitlements with iCloud Container Identifiers Ubiquity Container Identifiers . . . . Thank you in advance!. B

I have a SwiftUI document-based app that for the sake of this discussion stores accounting information: chart of accounts, transactions, etc. Each document is backed by a SwiftData DB. I'd like to incorporate search into the app so that users can find transactions matching certain criteria, so I went to Core Spotlight. Indexing & search within the app seem to work well. The issue is that Spotlight APIs appear to be App based & not Document based. I can't find a way to separate Spotlight data by document. I've tried having each document maintain a UUID as a document-specific identifier and include the identifier in every CSSearchableItem. When performing a query I filter the results with CSUserQueryContext.filterQueries that filter by the document identifier. That works to limit results to the specific file for search operations. Index updates via CSSearchableIndexDelegate.reindex* methods seem to be App-centric. A user may have file #1 open, but the delegate is being asked to update CSSearchableItems for IDs in other files. Is there a proper way to use Spotlight for in-app search with a document-based app? Is there a way to keep Spotlight-indexed data local within the app & not make it available across the system? I.e. I'd like to search within the app only. System-level searches should not surface this data.

Subject: Need Assistance with App Clip Invocation via URL Hello Developers, I’m currently facing an issue with invoking my App Clip through a URL, specifically when the link is shared via iMessage or Email. Instead of launching the App Clip, the URL redirects to the website. Here’s my current configuration: Approved App with an App Clip Universal Links functioning correctly within the App (verified through AASA file hosted on the website) Associated Domain Entitlements included for both the App and the App Clip Universal Link is expected to invoke the App Clip if the App isn’t installed Advanced Experience configured in App Store Connect The default experience URL from App Store Connect successfully triggers the App Clip, but my custom URL does not. I suspect I might be missing a crucial configuration step. Has anyone encountered a similar issue or have suggestions on what else I should verify? Thank you in advance for your help!

"Error loading project" if let projectMain = project.mainPicture { currentProjectImage = getUIImage(picture: projectMain) } if let pictures = project.pictures { projectPicNumber = pictures.count // Get main image if let projectMain = project.mainPicture { if let imgThumbData = convertImageThumb(picture: projectMain) { project.mainPictureData = imgThumbData } } while (getTotalImagesToConvertForProject(project: project ) > 0) { convertImageBatch(project: project) } project.converted = true saveContext() viewContext.refreshAllObjects() } } } catch { print("Fetch Failed") } } } convertImageBatch function func convertImageBatch(project: Project) { autoreleasepool { let fetchRequestPic: NSFetchRequest<Picture> = Picture.fetchRequest() let projectPredicate = NSPredicate(format: "project = %@", project) let dataPredicate = NSPredicate(format: "pictureData == NULL") fetchRequestPic.predicate = NSCompoundPredicate(andPredicateWithSubpredicates: [projectPredicate, dataPredicate]) fetchRequestPic.fetchLimit = 5 fetchRequestPic.sortDescriptors = [NSSortDescriptor(keyPath: \Picture.dateTaken, ascending: true)] do { let pictures = try viewContext.fetch(fetchRequestPic) for picture in pictures { currentPicNumber = currentPicNumber + 1 if let imgData = convertImage(picture: picture), let imgThumbData = convertImageThumb(picture: picture) { // Save Converted picture.pictureData = imgData picture.pictureThumbnailData = imgThumbData // Save Image saveContext() viewContext.refreshAllObjects() } else { viewContext.delete(picture) saveContext() viewContext.refreshAllObjects() } } } catch { print("Fetch Failed") } } } And finally saving func saveContext() { do { try viewContext.save() } catch { let nsError = error as NSError fatalError("Unresolved error \(nsError), \(nsError.userInfo)") } }
