App Store Version Not Working on iOS 12
I recently released version 8.5.4 (build 188) using Cloud Build. During testing via TestFlight, the app worked correctly on an iPhone 6 running iOS 12.5.8. However, after the app was published on the App Store, I found that the same version does not open at all on iOS 12 devices. Previously, earlier versions (such as 8.5.3) were functioning properly on iOS 12. My app’s minimum deployment target is set to iOS 12.0. This issue appears only with the App Store version, while the TestFlight version works fine on the same device. Due to this, I have paused the phased release of version 8.5.4 to prevent further impact on users still running iOS 12. I would like guidance on the following: 1. Has there been any recent change or limitation affecting apps targeting iOS 12 on the App Store? 2. Is there a way to prevent iOS 12 users from downloading version 8.5.4 while allowing them to continue using version 8.5.3? 3. Is there any recommended approach to ensur

iOS 26.2 Simulator is not available for download
I'm trying to download the iOS 26.2 simulator, but it fails both in Xcode and via the command line. When I run: xcodebuild -downloadPlatform iOS -buildVersion 26.2 -exportPath ~/Downloads It returns: iOS 26.2 is not available for download. I would like to know: Why iOS 26.2 simulator cannot be downloaded at the moment. Whether iOS 26.2 simulator is still available, or if it has been removed or replaced. How to properly get and install the iOS 26.2 simulator. Any official explanation or solution would be greatly appreciated. Thank you!

iOS 26.3.0 TextToSpeech EXC_BAD_ACCESS
Hello Apple Developer Community, I'm seeing a persistent crash in my iOS app reported via Firebase Crashlytics. The issue only started appearing on devices running iOS 26.3.0 and above (the crash does not occur on lower iOS versions, and it's unrelated to my app's version number). Key points: My app does NOT use any Text-to-Speech (TTS) features whatsoever. No AVSpeechSynthesizer, no Speech framework, no related APIs called from our code. My app is primarily written in Objective-C (with some Swift components possibly via dependencies). The crash stack is entirely within Apple's private TextToSpeech framework, specifically in ausdk::BufferAllocator::instance(). I suspect it might be indirectly triggered by a third-party ad SDK (e.g., Google Mobile Ads, AppLovin, etc.) that could be loading or interacting with accessibility features in the background — but this is just a hypothesis, as I have no direct evidence yet. Here is one representative crash log: Crashed: com.apple.root.user-in

Combining NavigationSplitView and TabView in iOS 18
Hi folks, I've used a NavigationSplitView within one of the tabs of my app since iOS 16, but with the new styling in iOS 18 the toolbar region looks odd. In other tabs using e.g. simple stacks, the toolbar buttons are horizontally in line with the new tab picker, but with NavigationSplitView, the toolbar leaves a lot of empty space at the top (see below). Is there anything I can do to adjust this, or alternatively, continue to use the old style? Thanks!

TN3134 clarification: DNS Proxy Provider unusable without MDM on iOS?

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

You need to specify the architecture for the new runtimes e.g. xcodebuild -downloadPlatform iOS -buildVersion 23D8133 -exportPath ~/Downloads -architectureVariant universal Without architectureVariant I get the extremely misleading error iOS 23D8133 is not available for download.

Reply to iOS 26.3.0 TextToSpeech EXC_BAD_ACCESS
We see this issue in iOS 26.3 as well, but it can reproduce almost every time if we build the app with Xcode 26.4 and run the app on an iOS 26.3 device. Also sent: FB22305926 with the crash log.

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.
