TN3134 clarification: DNS Proxy Provider unusable without MDM on iOS?
Hi, I’m looking for clarification on TN3134: Network Extension provider deployment, specifically iOS deployment requirements for: packet tunnel provider DNS proxy provider From the documentation: Packet Tunnel Provider App extension (min iOS 9.0): per-app mode requires a managed device DNS Proxy Provider App extension (min iOS 11.0): supervised devices only App extension (min iOS 11.0): per-app mode requires managed devices Issue I implemented a DNS proxy using NEDNSProxyManager.

Reply to Migrating to the UIKit scene-based life cycle
Thank you for your response, Richard. I have a follow-up question to clarify the exact trigger for the launch failure. Could you tell us which of the following scenarios actually causes the app to fail to launch? Built with Xcode 26 (iOS 26 SDK), run on an iOS 27 device — Does the app fail to launch simply because the device is running iOS 27, even though it was built with the older(=26) SDK? Built with Xcode 27 (iOS 27 SDK), run on any OS version including iOS 27 — Does the failure occur across all OS versions, including iOS 27(All OS versions(iOS15 or higher) supported by my app), as long as the app was compiled with the iOS 27 SDK without adopting the scene-based life cycle? Both of the above — Does the failure apply in either case? Understanding whether this is enforced at the OS level (runtime) or at the SDK/build level (compile time) is critical for planning our migration and release timeline. Thank you.

Reply to UI Glitch in Toolbar Menu Picker After Migrating to Xcode 26
However, This UI glitch We have noticed not only on Toolbar but wherever we are using dropdown(Menu+Picker) throughout the app. It created different shapes while disappearing such as circle and capsule. In iOS 26.0 it shows capsule and iOS26.2.1 it shows circle like UI while disappearing. Is this existing issue in XCode/iOS26, If yes, When we can expect the fix from Apple?

UI Glitch in Toolbar Menu Picker After Migrating to Xcode 26
I am experiencing a UI issue after migrating my app from Xcode 16 to Xcode 26. In my implementation, I have a toolbar that contains multiple buttons along with a dropdown menu. The hierarchy for dropdown is as follows: **Toolbar → ToolbarItem → View → Menu → Picker ** Prior to Xcode 26, this setup worked smoothly in production builds. The dropdown (Menu + Picker) behaves as expected, and selecting a value triggers loading a dataset containing thousands of records on the screen. However, after upgrading to Xcode 26, I am observing an animation glitch when dismissing the dropdown after a selection is made. Specifically, the dropdown briefly shows a “capsule-like” animation artifact during dismissal, which persists for a few seconds. This visual issue is noticeable and negatively impacts the perceived performance and user experience of the app. This issue is occurring in an already released app built with Xcode 26. Questions: Is this a known issue or regression in Xcode 26 / SwiftUI Menu or Picker compo

How to manually install iOS 26 Simulator download archive?
For difficult reasons I won’t get into, I ended up manually downloading the latest iOS 26 simulator runtime. I now have a file named 78756498-8AB4-4E5A-986C-7AA435758657.aar copied to my Mac. How do I get this archive installed so Xcode 26 recognizes it as a proper simulator runtime component? All searching I‘ve done for manually installing simulators references dmg files and older versions of Xcode. There’s no mention of aar files. When I tried the command: sudo xcrun simctl runtime add ./78756498-8AB4-4E5A-986C-7AA435758657.aar I get the result: An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=22): Error while creating AEA backend Invalid argument I tried to use Archive Utility to open the file but that just says it is unable to expand the file. I even tried renaming the file with a dmg extension and then tried mounting the file and I get the same “AEA backend” error. My Mac doesn’t have sufficient Internet access to let me download and install this normally through

Reply to ‌Xcode26-built apps cannot run on iPhone 6 or earlier devices‌
Thanks for the update. Just to clarify: Starting from April we must use Xcode 26.X to upload apps to the App Store (using older Xcode versions will fail). In addition, Xcode 26.X deployment target is iOS 15+. So, no option to release apps targeted to older iOS versions? If this is the case, why this isn't blocked during the Xcode build process? or even during the App Store processing? Also, what about the apps we already published a week ago with target deployment 12.0?

Reply to ‌Xcode26-built apps cannot run on iPhone 6 or earlier devices‌
Thank you for the reply, but according to the requirements on this link https://developer.apple.com/cn/app-store/submitting/, starting from April 2026, apps uploaded to App Store Connect must use iOS 26 SDK, which means Xcode 26 is also required. This seems contradictory to resolving the current issue. Could you provide the specific reason for the aforementioned problem? Why could the ipa compiled with Xcode 26 a week ago be installed, run, and used on an iPhone 6 12.5.8?

DeviceActivityMonitor extension rejected by App Store Connect validator — NSExtensionPointIdentifier "com.apple.deviceactivity.monitor" invalid (IrisAPI -19241)
Hi everyone, I'm building an iOS app that uses a DeviceActivityMonitor app extension as part of the Screen Time / Family Controls API. Every time I try to upload my IPA to App Store Connect, the validation fails with this error: Invalid Info.plist value. The value of the NSExtensionPointIdentifier key, com.apple.deviceactivity.monitor, in the Info.plist of 'Alexandria.app/PlugIns/AlexandriaActivityMonitor.appex' is invalid. Error Domain=IrisAPI Code=-19241, iris-code=STATE_ERROR.VALIDATION_ERROR What I have verified (everything looks correct): NSExtensionPointIdentifier = com.apple.deviceactivity.monitor NSExtensionPrincipalClass = AlexandriaActivityMonitor.AlexandriaActivityMonitorExtension (correctly resolved in the compiled binary, verified with plutil -p) The Swift class correctly subclasses DeviceActivityMonitor CFBundleShortVersionString matches the main app Both the main app and extension provisioning profiles explicitly contain com.apple.developer.family-controls = true (verified by inspectin

UIView + CATiledLayer + SwiftUI Hosting + iOS 26 = Crash?
Our app uses a UIView backed by a CATiledLayer that is embedded in a UIScrollView, to represent a large document viewer. (PDF data, actually.) It needs to be big - far too big to allocate a single layer, and it needs to be able to reveal more detail as you zoom in. This is the exact use case for a CATiledLayer. CATiledLayer does its drawing on a background thread, as you know, and we've always taken care to make our draw method thread-safe. It has worked great for us, for over a decade now. However, starting with iOS 26, we've been having some surprising crashes. It looks like our CATiledLayer (I think?) is trying to trigger a layout on the background thread as well. This is frustrating because it doesn't have any subviews or sublayers - there's no reason for it. I'm suspecting the CATiledLayer because it does its drawing on a thread, so maybe it would also do other things there, but honestly, I'm not sure - it's hard to tell. Here's the crash. Normally with a crash like this, the solution is to boun

Screen Time APIs showing severe inconsistencies (DeviceActivity not firing + impossible usage data)
Hi everyone, I’m the developer of one sec, an app used by a large number of users globally to reduce time spent on social media and to build healthier digital habits. Because of this, we rely heavily on Apple’s Screen Time / DeviceActivity / FamilyControls, ManagedSettings APIs – and unfortunately, we’re seeing increasingly severe issues in production that directly impact hundreds of thousands of real iOS users. During the past years, we have been busy filing dozens of feedback requests for different Screen Time issues – and there has been no response from Apple at all. Developer Relations might be able to confirm that the bugs are present and that they ended up with the right team – but they are never addressed, neither are workarounds provided. Instead, the situation gets worse and worse. iOS 26 introduced a series of heavy regressions (which have been reported via Apple’s official bug report tool Feedback Assistant on iOS 26 beta 1 in June 2025 – and have not been addressed 10 Mo

Reply to Combining NavigationSplitView and TabView in iOS 18
With iOS 26.4, a white space has now appeared above the side navigation toolbar. But only when using NavigationSplitView within TabView. I hope this gets fixed; otherwise, I’ll have to write a custom TabView. Things had been quiet for a while, but now it’s annoying me again.
