"Rosetta was designed to make the transition to Apple silicon easier, and we plan to make it available for the next two major macOS releases – through macOS 27 – as a general-purpose tool for Intel apps to help developers complete the migration of their apps. Beyond this timeframe, we will keep a subset of Rosetta functionality aimed at supporting older unmaintained gaming titles, that rely on Intel-based frameworks."
What will happen to Rosetta 2 then? Most importantly, will the ability to emulate x86_64 containers and binaries in virtual machines persist? Will Rosetta 2 be blocked only from the App Store? Will apps be barred from Rosetta, only games be able to use it? Will it only support frameworks?

My scenario is to help users set up a full year's alarms at once. The dates for the alarms follow a specific pattern, but not fixed weekdays, so the fixed-date type is needed.

I want to update my iPhone 15 Pro to iOS 26 from iOS 18.5. I downloaded ipsw firmware. But iTunes and Apple Devices App requires update version of app for update to iOS 26.
But I use last version of iTunes / Apple Devices, which was realised 2 May, 2025.
That mean Apple need to update their apps for adaptation it to iOS 26 update?

Is it possible with the current AlarmKit framework?
I tried in code and also reading the docs but couldn't find anyway of doing it.
Even though you can create an alarm with no snooze button that doesn't prevent the user from snoozing via the device volume button, for example.

Hi, I didn't find any mentions in the doc about disabling the option for snoozing in an alarm. Although you can create an alarm without a snooze button using AlarmKit, the user can still snooze by clicking on the volume button, for example.

It looks like ExtensionKit (and ExtensionFoundation) is fully available on iOS 26 but there is no mention about this in WWDC.
From my testing, it seems as of beta 1, ExtensionKit allows the app from one dev team to launch extension provided by another dev team. Before we start building on this, can someone from Apple help confirm this is the intentional behavior and not just beta 1 thing?
I'm pleased to share some significant updates that have recently been released for our Hypervisor and Virtualization frameworks. We've focused on enhancing efficiency, expanding capabilities, and addressing common developer needs. I believe these will be valuable for many of you.
Here’s a look at what’s new:
Hypervisor Updates
We've introduced support for configuring the intermediate physical address (IPA) memory granularity of a VM. This allows for more granular memory mappings, enabling granularity sizes down to 4KB. This is particularly useful for certain specialized device drivers requiring finer memory control.
Virtualization Framework Updates
More Efficient VM Image Storage with ASIF: We've integrated support for the Apple Sparse Image Format (ASIF). This results in a smaller disk footprint and optimized transfer for VM disk images when using VZDiskImageStorageDeviceAttachment, improving storage efficiency.
Custom Network Topologies with vmnet: We've added support for vmnet custom network topologies. This enables more flexible VM-to-VM communication based on logical networks with customized configurations, useful for complex testing or development environments. See VZVmnetNetworkDeviceAttachment to get started.
Simplified VM Queue Discovery: It's now easier to discover a VM’s on-process thanks to a new property on VZVirtualMachine. This should aid in development and debugging when interacting directly with the VM's queue.
These are some of the key highlights of the first beta, and I'm looking forward to seeing how these improvements will be utilized. I encourage you to explore the documentation for full details on these features.
I've just watched Scott Herschel's WWDC 25 session "Use structured concurrency with Network framework" and I am more than overjoyed to see said framework offer these new features.
However, the documentation has not yet been updated (or it's not where I expect to find it) .. Is there more that I can read about the enhancements to the framework?
One specific question is whether the structured concurrency portion of the framework's enhancement is backward compatible to before "26"?
I've recently updated one of our CI mac mini's to Sequoia in preparation for the transition to Tahoe later this year. Most things seemed to work just fine, however I see this dialog whenever the UI Tests try to run.
This application BoostBrowerUITest-Runner is auto-generated by Xcode to launch your application and then run your UI Tests. We do not have any control over it, which is why this is most surprising.
I've checked the codesigning identity with codesign -d -vvvv
as well as looked at it's Info.plist and indeed the usage descriptions for everything are present (again, this is autogenerated, so I'm not surprised, but just wanted to confirm the string from the dialog was coming from this app)

Additionally, spctl --assess --type execute BoostBrowserUITests-Runner.app return an exit code of 0 so I assume that means it can launch just fine, and applications are allowed to be run from "anywhere" in System Settings.
I've found the XCUIProtectedResource.localNetwork value, but it seems to only be accessible on iOS for some reason (FB17829325).
I'm trying to figure out why this is happening on this machine so I can either fix our code or fix the machine. I have an Apple script that will allow it, but it's fiddly and I'd prefer to fix this the correct way either with the machine or with fixing our testing code.
In the new update of macOS 26 Tahoe, I have noticed that on my MacBook Air M3, I am not getting a warning when my battery is low or when it's about to go to sleep. My MacBook is just turning off without warning.

Notifications
Starting in iOS 26, two notable changes have been made to CallKit, LiveCommunicationKit, and the PushToTalk framework:
As a diagnostic aid, we're introducing new dialogs to warn apps of voip push related issue, for example when they fail to report a call or when when voip push delivery stops. The specific details of that behavior are still being determined and are likely to change over time, however, the critical point here is that these alerts are only intended to help developers debug and improve their app. Because of that, they're specifically tied to development and TestFlight signed builds, so the alert dialogs will not appear for customers running app store builds. The existing termination/crashes will still occur, but the new warning alerts will not appear.
As PushToTalk developers have previously been warned, the last unrestricted PushKit entitlement ("com.apple.developer.pushkit.unrestricted-voip.ptt") has been disabled in the iOS 26 SDK. ALL apps that link against the iOS 26 SDK which receive a voip push through PushKit and which fail to report a call to CallKit will be now be terminated by the system, as the API contract has long specified.

Noticing a few issues with Screen Savers in macOS Tahoe developer beta 1 :
The command
open x-apple.systempreferences:com.apple.ScreenSaver-Settings.extension
no longer works to open the Screen Savers preference pane. The reason? There is no longer a Screen Saver preference pane - it still exists, but it's now a Modal dialog (that can not be resized) that is opened from within the Wallpaper preference pane, by clicking a button.
Something funny is happening with legacyScreensaver - I think that
ScreenSaverView.Init(frame:isPreview)
may be passing wrong values, e.g. the isPreview boolean is false in Preview mode?
I've submitted Feedback # FB17895600 about some of these, and will report back more as I figure things out.
Please feel free to add to this thread, thanks!
Did iOS 18.4 ( and 18.5) with iPhone 14 or 15 introduce new network connectivity or battery optimization policies that would break Local Push Connectivity? (suspend PushProvider in a new way that prevents it from listening and reponding to incoming messages from private network server)?
We have a private app using local push connectivity for real time local alerts on a local private network & server. The current application version works on prev devices including iPhone 12, iOS 14-18.1 that we know of.
A new(er) installation with iPhone 14s & 15s on iOS 18.4 is having new connectivity problems that seem to occur along with sleep. Previously NEAppPushProvider could listen and reply to incoming messages from server for local notifications, incoming sip invites, and connection health messages.
We'll be performing addtional testing to narrow the issue in the meantime, but it would be VERY helpful to have clarification regarding any iOS minor patches since 18.1 that are now breaking existing Local Push Connectivity applications.
If so what are the recommendations or remedies.
Are known issues with Network Extensions patched in 18.5?
Are existing applications expected to redesign their networking solutions for 18.3 & 18.4?
Did iOS18 versions later than 18.1 begin requiring new entitlements or exceptions for private apps in app store?
Hi there, I am working on an app that configures a PacketTunnelProvider to establish a VPN connection. Unfortunately, while a VPN connection is established, I am unable to update the app via testflight. Downloading other app updates works fine.
I noticed that after I receive the alert that updating failed, the vpn badge appears at the top of my screen (the same ux that occurs when the connection is first established). So it's almost like it tried to close the tunnel, and seeing that the app update failed it restablishes the tunnel.
I am unsure of why I would not be able to update my app. Maybe stopTunnel is not being called with NEProviderStopReason.appUpdate?
Can the Xcode 26 code assist feature be used in a macOS 26 virtual machine? I am not seeing a way to enable it...

Hi everyone,
I'm working on a library application that uses ISO15693 NFC tags embedded in books to track checkout status. These tags are password-protected and require secure access in order to write the AFI (Application Family Identifier) field, which we use to mark books as checked out.
According to the tag spec (ST SL2S2602), the flow for writing to a protected AFI requires:
Sending Get Random Number (custom command 0xB2)
Sending Present Password (custom command 0xB3)
Writing AFI using Write AFI (0x27)
We’re using Core NFC's customCommand(requestFlags:customCommandCode:customRequestParameters:) on NFCISO15693Tag. While basic tag operations like getSystemInfo() and readSingleBlock() work fine, any customCommand immediately fails with this error:
Error Domain=NFCError Code=100 "Tag connection lost"
This only happens on tags that return ICRef = 0x01 in the system info response. The exact same tags and command sequence work fine on Android (transceive) and in desktop NFC tools. It looks like iOS is silently rejecting custom commands on these older tags.
Has anyone found a workaround for this? Or is this a known Core NFC limitation?
Would love to hear:
If customCommand works for you with tags reporting ICRef = 0x01
If Apple has documented ICRef restrictions for customCommand
If there’s a list of supported tag ICRefs or recommended replacements (e.g., ICRef ≥ 0x11?)
We’re happy to switch to a supported tag type if necessary — but we’d prefer an official answer or guidance before reconfiguring our whole tag supply chain.
Thanks in advance for any help!
I have an app that uses NSPersistentCloudKitContainer stored in a shared location via App Groups so my widget can fetch data to display. It works. But if you reset your iPhone and restore it from a backup, an error occurs:
The file "Name.sqlite" couldn't be opened. I suspect this happens because the widget is created before the app's data is restored. Restarting the iPhone is the only way to fix it though, opening the app and reloading timelines does not. Anything I can do to fix that to not require turning it off and on again?
I have non-consumable and consumable in-app purchases in my app. The tutorial I was following stated Transaction.currentEntitlements includes unfinished consumables, which is incorrect according to the documentation. Is the correct way to handle unfinished consumables (and non-consumables) to implement Transaction.updates and call finish() if it’s verified? The documentation says that listener will receive unfinished transactions once upon app launch, so with that, do I understand correctly you do not need to implement Transaction.unfinished unless you want to look for unfinished transactions manually later on? Otherwise what is the correct and most recommended way to handle unfinished consumables? Is there a way to test that scenario in Xcode?
I am experiencing a critical issue with HealthKit authorization in iOS 18.5 where requestAuthorization() calls are immediately denied without showing the user permission dialog.
Problem Description:
HealthKit authorization requests immediately return .sharingDenied status
No system permission dialog is displayed to the user
Authorization status changes from .notDetermined to .sharingDenied in <0.1 seconds
This occurs for all HealthKit data types (step count, heart rate, sleep analysis, etc.)
Technical Details:
iOS Version: 18.5 (22F76)
Xcode Version: 16F6
Device: iPhone (tested on both simulator and physical device)
Bundle IDs tested: com.hereforyou.test2024, com.hereforyou.app
Entitlements: com.apple.developer.healthkit = true
Code Implementation:
let healthStore = HKHealthStore()
let stepType = HKObjectType.quantityType(forIdentifier: .stepCount)!
// Status before request: .notDetermined
try await healthStore.requestAuthorization(toShare: [], read: [stepType])
// Status after request: .sharingDenied (immediate, <0.1 seconds)
Evidence this is not a code issue:
Other HealthKit apps from App Store work correctly on the same device
Proper entitlements are configured and verified
HKHealthStore.isHealthDataAvailable() returns true
Same code worked in previous iOS versions
Multiple Bundle IDs tested with same result
Expected Behavior:
System should display HealthKit permission dialog allowing user to grant/deny access
Actual Behavior:
Authorization is immediately denied without user interaction
Steps to Reproduce:
Create new iOS app with HealthKit entitlements
Call requestAuthorization() for any HealthKit data type
Observe immediate denial without permission dialog
Is this a known issue in iOS 18.5? Are there any workarounds or timeline for a fix?
Best regards

Hi, I’m trying out my app with Xcode 26, running on an iOS 26 simulator. I'm having issues with URLSessions, it crashes when I set the URLSessionConfiguration to default, and if I don’t use the URLSessionConfiguration, it crashes if I use URLSession.shared. When running in a real device, it doesn't crash, but any network request will hang and time out after a while.
Is it a known issue in the latest beta versions?
