Hi everyone, I'm developing a CarPlay application and using a CPTabBarTemplate to display multiple tabs. I want to determine which tab is selected when the user clicks on a tab, specifically when switching to the second tab. Here’s the relevant part of my code: class CarPlaySceneDelegate: UIResponder, CPTemplateApplicationSceneDelegate { var interfaceController: CPInterfaceController? var tabBarTemplate: CPTabBarTemplate = CPTabBarTemplate(templates: []) func templateApplicationScene( _ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController ) { self.interfaceController = interfaceController // Create and set the TabBarTemplate let tabBarTemplate = createTabBarTemplate() self.tabBarTemplate = tabBarTemplate interfaceController.setRootTemplate(tabBarTemplate, animated: false) { success, error in if let error = error { print("Error setting TabBarTemplate: \(error.localizedDescription)") } else { print("TabBarTemplate set successfully.") } } } func createTabBarTemplate() -> CPTabBarTemplate { let listItem1 = CPListItem(text: "Item 1", detailText: "Detail 1") let listItem2 = CPListItem(text: "Item 2", detailText: "Detail 2") let listTemplate = CPListTemplate( title: "List", sections: [CPListSection(items: [listItem1, listItem2])] ) let gridButton1 = CPGridButton( titleVariants: ["Grid 1"], image: UIImage(systemName: "star.fill")! ) let gridButton2 = CPGridButton( titleVariants: ["Grid 2"], image: UIImage(systemName: "star")! ) let gridTemplate = CPGridTemplate( title: "Grid", gridButtons: [gridButton1, gridButton2] ) return CPTabBarTemplate(templates: [listTemplate, gridTemplate]) } }

I updated to iPadOS 18.2, i have a iPad Pro M2 11 inch, and this is what happens, can someone explain on how to fix this. (this is for users and Apple Developers only)

We have a IOS app and we are using the same app for Mac Catalyst. In IOS we are able to detect when user take the screenshot using UIApplicationUserDidTakeScreenshotNotification. But in MACCatalyst it is not working. As per docs UIApplicationUserDidTakeScreenshotNotification and UIScreenCapturedDidChangeNotification are both supported for MacCatalyst 13.1+. But I am not getting screen shot notifications using both

[The problem that is occurring] The game apps in development are compatible with iOS, macOS, tvOS, and visionOS. In the Game app under development, the AppleArcade access point is placed in the main menu. In visionOS, when the main menu is opened, the GameCenter dashboard is automatically launched within 1~2 seconds after the main menu is displayed. This condition occurs every time the menu is re-opened. On iOS, macOS, and tvOS, the dashboard appears after pressing the GameCenter access point icon. [What you want to solve] We would like to make it so that the Game Center dashboard is launched after the access point icon is pressed on visionOS as it is on other operating systems. Or, if there is a standard implementation method for visionOS, please let us know.

System Settings is recommending I review the settings for my two children. The UI has a bug where it always opens the top most child even if I select the bottom of the two. Was present in 15.1.1 and is still present after installing 15.2

Greetings all, Would anyone be able to assist and tell me why on my desktop Button( auto completion shows 1 choice () (action: @escaptin () -> Void, label: @escaping () -> Label) while on my laptop, Button( auto completion shows more choices, starting with I (_ configuration:) I (action:label:) etc.... How do I get my desktop to act like my laptop?

In one of my apps I use an app group to share data between the app and a command line tool. This works as expected. The app also contains a Dock Tile plugin and I wonder if there's a way to access the group container from this plugin? Thanks in advance for your help. Best regards, Marc

I am developing a library for RichTextEditor for SwiftUI, and I am facing issues with implementing NSParagraphStyle related features like nested bullet lists and text alignment. I have searched a lot and personally feel that the documentation is not enough on this topic, so here I want to discuss how we can achieve the nested list with UI/NSTextView and natively available NSTextList in NSParagraphStyle.textLists. The problem is I am not able to understand how I can use this text list and how to manage adding list and removing list with my editor I have seen code that work adding attributes to each string and then merge them, but I don't want that, I want to add/update/remove attributes from selected text and if text is not selected then want to manage typing attributes to keep applied attributes to current position

I am encountering an issue where the Share Extension in my app fails to launch intermittently. In my project, NSExtensionPrincipalClass is set to ComposeShellVC. When the Share Extension launches successfully, the following log entry appears, indicating that ComposeShellVC is being created: 09:21:09.339190+0800 2254529 ViewServices com.apple.UIKit compose-shareextension Received request to create view controller: self: <_UIViewServiceViewControllerOperator: 0x109194c00>; class: compose_shareextension.ComposeShellVC; contextToken: 42EA1BDB-5CDF-4EBD-8503-8A9A04BCE41C However, when the bug happens, this entry is absent during the failed launches. Additionally, I am unable to set breakpoints within the Share Extension to further investigate. Could you provide guidance on the next steps to diagnose this issue? Any advice on debugging techniques or tools that can help pinpoint the cause of this behavior would be greatly appreciated.

I have my app accepting images shared from Photos but from the screenshot editor, my app icon does not show as a destination for the screenshot. Do I have to build an app extension or app intent catcher to then pass along the screenshot? It the problem that the screenshot editor is a modal sheet holding my app interface. I want to catch the screenshot in background for processing.

I want to get the content present in a note or a mail thread when my cursor is in it on macos. (In the focused element). But I don't succeed to get any element from both mail and notes using : let result = AXUIElementCopyAttributeValue(appRef, kAXFocusedUIElementAttribute as CFString, &focusedElement) Even when I want to check the available attribute : let result = AXUIElementCopyAttributeNames(element, &attributeNames) I got AXUIElementCopyAttributeNames result: AXError(rawValue: -25204) But I have the write permission because when I am running AXIsProcessTrusted() to see if I got accessible permission it don't throw an error Is it possible to do it that way or I have to change

Hi! So while Date is supported for @Parameter in an App Intent, I just discovered that Xcode will not let me use use it in a parametrized App Shortcut phrase. In my case, I would like to give the option to say "today", tomorrow", or "day after tomorrow" for the date. Am I missing something? Any hints on the best way to approach this?

Hello, I am encountering compatibility issues with older JavaScript frameworks, specifically Ext JS 4.0 and Sencha Touch 2.0, after upgrading to iOS 18.2 Beta. My application, which was working fine on previous versions of iOS, is now experiencing rendering issues, broken touch events, and performance degradation on WebKit in iOS 18.2. The issues I’m seeing include: Sencha Touch 2.0: The UI elements (like fields, and lists) are not interactive or showing their content properly. There also seems to be a delay in rendering touch events. This seem to no longer work as expected with the updated WebKit engine in iOS 18.2 Beta. My Questions: Are there any known issues with legacy JavaScript frameworks like Ext JS 4.0 and Sencha Touch 2.0 on iOS 18.2 Beta? Specifically, do these frameworks rely on older DOM methods or JavaScript features that might be deprecated in the latest WebKit engine? Has Apple officially deprecated any JavaScript features or DOM methods in WebKit that might be causing these issues? If so, are there recommended workarounds or updates to ensure compatibility with iOS 18.2? Is there a way to enable legacy JavaScript features or fallback modes in iOS 18.2 ? I would appreciate any guidance on this, as we are facing significant issues with our app’s performance and UI since upgrading to iOS 18.2. Thank you!

I have noticed a discrepancy between behavior on physical devices and simulators in iOS 18. I am using the latest MapKit APIs to fetch MKMapItems using the following MKLocalSearch: private func performLocalSearch(_ query: String) async throws -> [MKMapItem] { let request = MKLocalSearch.Request() request.naturalLanguageQuery = query let search = MKLocalSearch(request: request) return try await search.start().mapItems } This returns an array of MKMapItem on both the simulator and physical device. The key difference is my physical device (iOS 18.1.1) is missing the MKMapItem's identifier value. On the simulator, identifier is always populated in addition to my search. Any ideas on how to resolve this? The new MapKit API for those curious: @available(iOS 6.0, *) open class MKMapItem : NSObject { @available(iOS 18.0, *) open var identifier: MKMapItem.Identifier? { get }

While the application is running in the background, I need to take a screenshot and save it in the photos folder. When I try with my test app, it takes only the front of the application. How can I take a screenshot in the background?

I have a CALayer and I'd like to animate a property on it. But, the property that triggers the animation change is different to the one that is being changed. A basic example of what I'm trying to do is below. I'm trying to create an animation on count by changing triggerProperty. This example is simplified (in my project, the triggerProperty is not an Int, but a more complex non-animatable type. So, I'm trying to animate it by creating animations for some of it's properties that can be matched to CABasicAnimation - and rendering a version of that class based on the interpolated values). @objc class AnimatableLayer: CALayer { @NSManaged var triggerProperty: Int @NSManaged var count: Int override init() { super.init() triggerProperty = 1 setNeedsDisplay() } override init(layer: Any) { super.init(layer: layer) } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } override class func needsDisplay(forKey key: String) -> Bool { return key == String(keypath: \AnimatableLayer.triggerProperty) || super.needsDisplay(forKey: key) } override func action(forKey event: String) -> (any CAAction)? { if event == String(keypath: \AnimatableLayer.triggerProperty) { if let presentation = self.presentation() { let keyPath = String(keypath: \AnimatableLayer.count) let animation = CABasicAnimation(keyPath: keyPath) animation.duration = 2.0 animation.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.linear) animation.fromValue = presentation.count animation.toValue = 10 return animation } } return super.action(forKey: event) } override func draw(in ctx: CGContext) { print("draw") NSGraphicsContext.saveGraphicsState() let nsctx = NSGraphicsContext(cgContext: ctx, flipped: true) // create NSGraphicsContext NSGraphicsContext.current = nsctx // set current context let renderText = NSAttributedString(string: "\(self.presentation()?.count ?? self.count)", attributes: [.font: NSFont.systemFont(ofSize: 30)]) renderText.draw(in: bounds) NSGraphicsContext.restoreGraphicsState() } func animate() { print("animate") self.triggerProperty = 10 } } With this code, the animation isn't triggered. It seems to get triggered only if the animation's keypath matches the one on the event (in the action func). Is it possible to do something like this?

Hello Apple Developer Community, I am encountering an issue with app icon rendering after updating an app on devices running iOS 18 or newer. Below are the details: Issue Summary: When updating an app from a previous version (with separate light and dark mode icons) to the latest version (where both modes use the same icon), the icon changes are not reflected consistently across all system menus. Steps to Reproduce: Set the device mode to Dark Mode. Install the previous app version (with different icons for light and dark modes). Update the app to the latest version (where both modes use the same icon). Change the device mode to Light Mode. Switch back to Dark Mode. Expected Behavior: The app icon should remain consistent across all system menus (Home Screen, Spotlight search, etc.) when switching between Light and Dark Modes. Observed Behavior: The app icon displays correctly on the Home Screen but inconsistencies appear in other menus, such as Spotlight search or when toggling between modes. For instance, in Dark Mode, the icon may revert to the previous black-colored logo or display incorrectly compared to the updated design. Additional Notes: The asset catalog is configured correctly, with identical icons set for both light and dark modes in the latest app version. Incrementing the build number was implemented during the update. A manual device restart resolves the issue on some devices, but not consistently. Questions for the Community: Has anyone else experienced similar app icon caching or rendering issues in iOS 18 or later? Are there known workarounds or specific configurations to ensure consistent icon rendering across all system menus? Could this be related to iOS 18's icon caching or appearance handling mechanisms? Your insights and suggestions would be greatly appreciated. Thank you for your time!

In my iOS App I present a QLPreviewController where I want to display a locally stored Video from the iPhone's document directory. let previewController = QLPreviewController() previewController.dataSource = self self.present(previewController, animated: true, completion: nil) func previewController(_ controller: QLPreviewController, previewItemAt index: Int) -> QLPreviewItem { let url = urlForPreview return url! as QLPreviewItem } This seems to work fine for all but one of my testflight users. He is using an iPhone 12 with iOS18.0.1. The screen becomes unresponsive. He cannot pause the video, share it or close the QLPreviewController. In his logfile I see the following error... [AVAssetTrack loadValuesAsynchronouslyForKeys:completionHandler:] invoked with unrecognized keys ( "currentVideoTrack.preferredTransform") Any ideas?.

Problem I am developing a WebDriver agent for automation and using dictionaryRepresentation to retrieve the coordinates of the iOS app hierarchy. However, I am encountering an issue with the accuracy of the x and y coordinates. Approach Tried I tested the setup on: iPhone 12 Pro Max (iOS 16.2): Accuracy issues with the coordinates were observed. iPhone SE (3rd Generation) (iOS 16.2): Coordinates were accurate for tap actions, with no issues identified. Observation It appears that devices with fingerprint biometric authentication provide accurate coordinates. Can anyone help here to understand is there anything wrong in the code. Are do we have to adjust frame of the element for different devices? Sample Code - (NSDictionary *)json_tree { NSDictionary<XCUIElementAttributeName, id> *dictionaryRepresentation = [[self snapshotWithError:nil] dictionaryRepresentation]; return [self.class dictionaryForElementAttributes:dictionaryRepresentation recursive:YES]; } // This method converts the dictionary to CGRect, handling any broken frame values (e.g., Infinity) + (CGRect)handleBrokenFrameFromDict:(id)frameDict { if ([frameDict isKindOfClass:[NSDictionary class]]) { CGFloat originX = [frameDict[@"X"] floatValue]; CGFloat originY = [frameDict[@"Y"] floatValue]; CGFloat sizeWidth = [frameDict[@"Width"] floatValue]; CGFloat sizeHeight = [frameDict[@"Height"] floatValue]; CGRect frame = CGRectMake(originX, originY, sizeWidth, sizeHeight); // Replace Infinity values with CGRectZero return (isinf(frame.size.width) || isinf(frame.size.height) || isinf(frame.origin.x) || isinf(frame.origin.y)) ? CGRectZero // or another predefined constant like BROKEN_RECT : CGRectIntegral(frame); } return CGRectZero; // If frameDict is not a valid dictionary, return CGRectZero } // This method converts CGRect into a dictionary representation for "rect" + (NSDictionary *)rectDictionaryFromCGRect:(CGRect)rect { return @{ @"x": @(rect.origin.x), @"y": @(rect.origin.y), @"width": @(rect.size.width), @"height": @(rect.size.height) }; } + (NSString *)label:(NSDictionary<XCUIElementAttributeName, id> *)dict { XCUIElementType elementType = [dict[XCUIElementAttributeNameElementType] intValue]; NSString *label = dict[XCUIElementAttributeNameLabel]; if (elementType == XCUIElementTypeTextField || elementType == XCUIElementTypeSecureTextField) { return label; } return FBTransferEmptyStringToNil(label); } + (NSString *)name:(NSDictionary<XCUIElementAttributeName, id> *)dict { NSString *identifier = dict[XCUIElementAttributeNameIdentifier]; if (nil != identifier && identifier.length != 0) { return identifier; } NSString *label = dict[XCUIElementAttributeNameLabel]; return FBTransferEmptyStringToNil(label); } + (NSString *)value:(NSDictionary<XCUIElementAttributeName, id> *)dict { id value = dict[XCUIElementAttributeNameValue]; XCUIElementType elementType = [dict[XCUIElementAttributeNameElementType] intValue]; if (elementType == XCUIElementTypeStaticText) { NSString *label = [self label:dict]; value = FBFirstNonEmptyValue(value, label); } else if (elementType == XCUIElementTypeButton) { NSNumber *isSelected = [dict[XCUIElementAttributeNameSelected] boolValue] ? @YES : nil; value = FBFirstNonEmptyValue(value, isSelected); } else if (elementType == XCUIElementTypeSwitch) { value = @([value boolValue]); } else if (elementType == XCUIElementTypeTextView || elementType == XCUIElementTypeTextField || elementType == XCUIElementTypeSecureTextField) { NSString *placeholderValue = dict[XCUIElementAttributeNamePlaceholderValue]; value = FBFirstNonEmptyValue(value, placeholderValue); } value = FBTransferEmptyStringToNil(value); if (value) { value = [NSString stringWithFormat:@"%@", value]; } return value; } + (NSDictionary *)dictionaryForElementAttributes:(NSDictionary<XCUIElementAttributeName, id> *)dict recursive:(BOOL)recursive { NSMutableDictionary *info = [[NSMutableDictionary alloc] init]; info[@"type"] = [FBElementTypeTransformer shortStringWithElementType:[dict[XCUIElementAttributeNameElementType] intValue]]; info[@"rawIdentifier"] = FBValueOrNull([dict[XCUIElementAttributeNameIdentifier] isEqual:@""] ? nil : dict[XCUIElementAttributeNameIdentifier]); info[@"name"] = FBValueOrNull([self name:dict]); info[@"value"] = FBValueOrNull([self value:dict]); info[@"label"] = FBValueOrNull([self label:dict]); // Handle the frame value CGRect frame = [self handleBrokenFrameFromDict:dict[XCUIElementAttributeNameFrame]]; info[@"frame"] = NSStringFromCGRect(frame); // Add the rect value info[@"rect"] = [self rectDictionaryFromCGRect:frame]; info[@"isEnabled"] = [@([dict[XCUIElementAttributeNameEnabled] boolValue]) stringValue]; // visible // accessible info[@"isFocused"] = [@([dict[XCUIElementAttributeNameHasFocus] boolValue]) stringValue]; if (!recursive) { return info.copy; } NSArray<NSDictionary<XCUIElementAttributeName, id> *> *childElements = [dict[XCUIElementAttributeNameChildren] isKindOfClass:[NSArray class]] ? dict[XCUIElementAttributeNameChildren] : @[]; if ([childElements count]) { info[@"children"] = [[NSMutableArray alloc] init]; for (NSDictionary<XCUIElementAttributeName, id> * childSnapshot in childElements) { [info[@"children"] addObject:[self dictionaryForElementAttributes:childSnapshot recursive:YES]]; } } return info; }

Exploring Live Activity feature for Apple Watch right now and found that it has this default view with "Open on iPhone" button when you tap Live Activity. That button perfectly brings iOS app to foreground as if you tapped iOS's Live Activity. Is there a way to mimic that behavior from inside Watch app code? From inside WKApplicationDelegate, for example Tried openSystemURL but it seems lile it's only available for tel or sms links
