Hello! My app has been experiencing some strange crashes in the last few months. The crash log shows it as a Watchdog timeout error of 0x8BADF00D. I knew about this error code before, especially since here is the documentation about addressing-watchdog-terminations. But actually, the call stack shows that the crash appears in dydl and it seems that my app code has not been executed yet. Does anyone know the cause of this problem please? I have observed this crash on iOS 15.6, 15.5, 15.4, and earlier versions.

On iOS16, I can't open the audio chart details page via the Audio Graph defined by AXChartDescriptorRepresentable. When trying to open chart details through VoiceOver, the screen flashes for a moment (the content seems to be correct) and then disappears immediately. This behavior was normal on iOS 15, but it doesn't work from iOS 16 beta to RC. I have uploaded the sample project to https://github.com/gongzhang/audio-graph-example. It needs to be running on a physical iOS 16 device with VoiceOver enabled to operate. Run the sample project Open the Audio Graph detail page, by using VoiceOver, swiping down until you hear Chart details. The chart detail page disappears immediately. Reported FB11479931

I found that watchOS 9.2 seems to break the complicationForeground() modifier. In previous systems, a View modified by complicationForeground() was rendered white, while an unmodified View was rendered with the watch face tint color. This is the correct behavior. However, in watchOS 9.2, this behavior has been reversed. The View modified by complicationForeground() renders the tint color, and the opposite is white‽ This causes third-party complications to look very inconsistent on tinted watch faces. Of course, this issue belongs to ClockKit, and I'm not sure if there are similar issues in the new WidgetKit. Will this issue be fixed please?

Hello! I'm trying to donate an Intent to iOS using IntentDonationManager, following the methods described in the documentaion. try await IntentDonationManager.shared.donate(intent: MyIntent()) // succeeded However, I'm not seeing any effect of this action anywhere in the system (iOS 17 and 16). I have debugged it on both the simulator and a physical device, and I have also enabled the "Display Recent Shortcuts" toggle in the developer settings, but I still don't see any relevant suggestions appearing. Similarly, the issue also occurs with the old SiriKit framework, where INInteraction.donate(completion:) doesn't seem to have any observable effect. I recall that in iOS 15, the simulator would immediately present the donated Shortcut action on the lock screen and Spotlight page. However, starting from iOS 16 and continuing to the current iOS 17 beta 1/2, I haven't been able to achieve the same behavior using the same code. Another similar report: https://developer.apple.com/forums/thread/723109 So is there any way to test or verify the results of this donation action?

Hi, I'm trying to apply the Vibrancy text style to SwiftUI Text. However, I didn't find proper API to do this. As the session video wwdc2023-10076 said, vibrancy brightens foreground content that displays on top of a material and works by pulling light and color forward from what's behind it. However, when I set .secondary foreground style to a Text, it's just some graycolor with a constant alpha value. It there any other API to achieve the vibrancy style? Thanks!

In Xcode 15 beta 6, I found that when building visionOS apps, #if os(iOS) is no longer considered part of the project. This behavior is different from beta 1 to beta 5. Is this intentional? This change has caused third-party dependencies that use #if os(iOS) and have not yet explicitly supported visionOS to fail to compile. Is there a way to switch back to the old behavior? After all, requiring all third-party dependencies to explicitly support visionOS is quite difficult.

Hello, My iOS app will support running on visionOS in compatible mode and I want to do some optimizations for the UI. Is there a flag can help to determine this compatible mode on visionOS? (Just like ProcessInfo.isiOSAppOnMac) Thanks! FB12757613

Hello everyone! I recently released the native visionOS version of my app on TestFlight. I noticed that there are 8 crashes on Vision Pro on the App Store Connect website, but I can't get these crash logs in Xcode Organizer (the crash list of visionOS app is empty). Is there any way to get these crash logs now? I don't have a physical Vision Pro device so I can't reproduce the crash, I can only rely on the crash logs.

Hello everyone! I've noticed that Xcode 15.2 is still not selectable as a build environment on Xcode Cloud, even though the official version of 15.2 has been out for several days. Is this part of the plan? Or is it a system bug? 🤔 I need 15.2 as the release environment, including support for building visionOS apps. I have already submitted FB13531029.

⌚️Hello, I've noticed in watchOS 10 that when a complication is in the Smart Stack, the value of WCSession.isComplicationEnabled is false. I'm not sure if this is intentional or a bug. It seems trivial at first glance, but it actually affects the communication mechanism mentioned in Implementing Two-Way Communication Using Watch Connectivity. In the following two scenarios, if the user has only added the app's complication to the Smart Stack, then the watch app will not be able to communicate properly with the iOS app. Scenario 1 - WCSession.transferCurrentComplicationUserInfo() // update complications from the iOS app if WCSession.default.isComplicationEnabled { let userInfoTransfer = WCSession.default.transferCurrentComplicationUserInfo(userInfo) // ... } As described in Implementing Two-Way Communication Using Watch Connectivity, when the iOS app proactively updates the data of the watch app, since WCSession.isComplicationEnabled is false, WCSession will refuse to transfer any data. This causes the standalone complication in Smart Stack to not be updated. Scenario 2 - WKApplicationRefreshBackgroundTask When the watch app uses WKApplication.scheduleBackgroundRefresh() to periodically update data, as long as the user has added the app's complication to the watch face, the corresponding WKApplicationRefreshBackgroundTask can be executed periodically in the background to fetch data. However, if the user has only added complication to the Smart Stack, then the watch app will be completely purged, and the background task will not be executed at all. Although WCSession.isComplicationEnabled is not directly used in this scenario, its behavior appears to be the same, that is, the complication in the Smart Stack is not considered a complication by the system. Should I submit a bug report?

Hello! I wanted to bring up an issue I've encountered with .popover(isPresented:). It does not show up above a TabView on iOS 18. This issue occurs on an iPad or on an iPhone when using the .popover compact adaptation modifier. (Xcode 16 beta 6 + iOS 18 beta 7)

Hello, I noticed a small mistake in the Human Interface Guidelines (HIG). On the page HIG > Components > System Experiences > Widget > watchOS Widget Dimensions, scroll down to the bottom. In the "watchOS widget dimensions" section, the sizes in the table are in pixels (px), not points (pt) actually. However, the table header indicates the sizes should be in points (pt). Page link: https://developer.apple.com/design/human-interface-guidelines/widgets#watchOS-widget-dimensions For example, the widget size in the Smart Stack on a 49mm watch should be 192x81.5 pt (or 382x163 px), not 382x163 pt. This size can be verified with the information provided here: https://developer.apple.com/documentation/watchos-apps/supporting-multiple-watch-sizes/. https://developer.apple.com/documentation/watchkit/wkinterfacedevice/1620974-screenscale

Hello, I'd like to ask a very fundamental question about JSONEncoder: how to sort keys in a specific order when encoding a dictionary to JSON text? I know there is an option called JSONEncoder.OutputFormatting.sortedKeys, but it sorts the keys only in lexicographic order. I want to sort the keys using a different comparator, such as String.localizedStandardCompare(_:), which achieves the "Finder-like" order. The reason why I ask this question is because I have a localization tool that works with String Catalog (xcstrings file, which is a JSON), but every time my tool serializes an xcstrings file, it always messes up the keys in lexicographic order (I used JSONEncoder + .sortedKeys). Meanwhile, Xcode 16 always serializes the string keys into the "Finder-like" order. As a result, my tool always generates a huge diff when manipulating the xcstrings even when making only a small modification to it. So I am wondering how Xcode 16 implements the String Catalog tool to serialize the JSON in "Finder-like" order. It would be great if JSONEncoder could do that too. Or, maybe I can use another serialization method to implement this behavior?

Hello, I added a new iOS 26 app icon created with Icon Composer (named AppIcon) to my app, while keeping the previous version's icon (in Asset Catalog format, also named AppIcon). However, I found that once the bundle contains the Icon Composer icon file, the app cannot be submitted to App Store Connect. I received the following App Store Connect errors: ITMS-90022: Missing required icon file - The bundle does not contain an app icon for iPhone / iPod Touch of exactly '120x120' pixels, in .png format for iOS versions >= 10.0. To support older versions of iOS, the icon may be required in the bundle outside of an asset catalog. Make sure the Info.plist file includes appropriate entries referencing the file. See https://developer.apple.com/documentation/bundleresources/information_property_list/user_interface. ITMS-90023: Missing required icon file - The bundle does not contain an app icon for iPad of exactly '152x152' pixels, in .png format for iOS versions >= 10.0. To support older operating systems, the icon may be required in the bundle outside of an asset catalog. Make sure the Info.plist file includes appropriate entries referencing the file. See https://developer.apple.com/documentation/bundleresources/information_property_list/user_interface.
