Reply to How to turn off background extension effect in UISplitViewController?
@DTS Engineer What's the point of filing a bug report? Will it actually get fixed? I'm asking a serious question because I've already filed several iOS/iPadOS 26 bug reports related to UISplitViewController and UIKit. Several were reported against beta 1. Those bug reports include trivial sample apps and step-by-step instructions demonstrating the issue. None have been fixed as of iOS/iPadOS 26.0 GM. I also have several outstanding bug reports for broken functionality about UISearchController/UISearchBar under iOS/iPadOS 26. Again, several since beta 1. All include trivial test apps that demonstrate the issue. Again, none have been fixed. All of these outstanding issues are impacting my app. I'm very frustrated and disappointed. I'm sorry but I no longer have the ambition to file more bug reports that will never be fixed. I truly hope Apple gets back to the days of it just works. That era seems to be lost at the moment. Every year iOS and others are updated with lots of new

How to detect modifier keys with hardware keyboard in SwiftUI (iOS)?
Hi everyone, In UIKit, I can detect which key and modifier keys are pressed from an external hardware keyboard using the pressesBegan method in a UIResponder: override func pressesBegan(_ presses: Set, with event: UIPressesEvent?) { for press in presses { if let key = press.key { print(Key: (key.charactersIgnoringModifiers ?? )) print(Modifiers: (key.modifierFlags)) } } } I am now working in SwiftUI (iOS), and I couldn’t find a direct equivalent for pressesBegan. What is the recommended way in SwiftUI to detect modifier keys + key presses from an external keyboard? Is there a built-in API, or should I always wrap a UIKit view/controller for this purpose? Thanks in advance!

Reply to Metal fails to create PSO on AMD based GPUs
Hello, Pre documentation Metal libraries built using Metal shader converter tools require a device that supports Argument Buffers Tier 2, running macOS 14 Sonoma, iOS 17 or later. If you build a Metal library for earlier OS versions, not all features will be supported. AMD GPUs lack many of the features offered by Apple Silicon and consequently PSOs won't compile (irrespective of Metal Shader Converter). Check the Metal Feature Set Tables for details.

Reply to Metal 4 support in iOS simulator
Hello, Metal 4 is expected to work on the Simulator with iOS 26. Given that this compiles on device and only fails to compile on Simulator this is a regression. Try importing Metal i.e. import Metal to see if that solves the problem. You can also see if this compiles with Obj-C. Otherwise please send us a bug report.

Custom USB Network Device Driver on iPhone
Hi, We are using the AX88772C as a USB->Ethernet bridge in a product we are developing. Due to the chip not following the NCM protocol, it is not supported by the default networking drivers on the iPhone. Initially, we intended on using DriverKit to develop a userspace driver for this device. However, we have been informed DriverKit is only available on iPad OS, not iOS. As such is the case, we have found two possible alternatives. First being IOkit, and the second being External Accessory Session (EASession). What are the limitations of each of these options? We need the ability to send and receive USB packets to Control and Bulk endpoints. Is this possible with either of the options defined above? Would either of these options require the device to be MFi certified? We have read that some APIs within IOkit require the apple device to be jailbroken. Is there a list of features that can be used without a jailbroken device? Documentation on these 2 options is limited, so any official documentation

AlarmKit plays system error tone instead of custom sound files (iOS 26.0)
AlarmKit custom sounds are universally broken in iOS 26.0 stable - instead of playing your custom sound, it plays a system error/timeout beep. I've spent days investigating why custom sounds result in what sounds like an error beep (like when you cancel an operation or hit a timeout) instead of the actual audio file. I can now prove this is an Apple bug, not implementation error. Evidence: Test 1: My Implementation Followed Apple's documentation exactly Tried both bundle and Library/Sounds (as documented) Result: System error beep (not my audio) Test 2: Professional Apps Tested ADHDAlarms (popular AlarmKit example by jacobsapps) https://github.com/jacobsapps/ADHDAlarms Their airhorn.mp3 custom sound: same error beep (not an airhorn) Their default sound: works perfectly Test 3: Device Testing Physical iPhone (iOS 26.0 - 23A341): broken iOS Simulator: broken Not device-specific Files are found correctly, but the actual audio file is never played. Instead, you hear what sounds like a s

Reply to Safe areas ignored after navigating a WebView/WebPage back in a NavigationStack
Yes, I'm having the same problem (with a wrapped WKWebView, but presumably also the new WebView). The jumping-on-back-button issue was also a problem before iOS 26, but you could work around it by using .ignoresSafeArea(.all, edges: .bottom) However, now in iOS 26, Apple wants the content to flow behind the toolbar, meaning the above fix is no longer suitable. Did you manage to find a workaround?

Reply to I Need some clarifications about FoundationModels
Happy to help answer some of these! Yes. The Foundation Models framework uses the on-device system foundation model. It's an ~3 billion parameter model designed and trained by Apple. Is the language model provided by FoundationModels designed and trained by Apple? Or is it based on an open‑source model? The exact same on-device model is available on iOS, iPadOS, macOS, and VisionOS on all devices that support Apple Intelligence. Is this on‑device model available on iOS (and iPadOS), or is it limited to macOS? No. The general on-device model you access via Foundation Models is not a coding model and isn't suitable for most code tasks. Xcode on Mac has a separate built-in coding model to help with code completion. When I write code in Xcode, is code completion powered by this same local model? If so, why isn’t the same model available in the left‑hand chat sidebar in Xcode (so that I can use it there instead of relying on ChatGPT)? Yes and no. You can give the on-device model access to that ki

Reply to App Clips don't work
We have the same issue. The appclip was working well before, but with iOS 26 we get the error This operation couldn't be completed. (ASDErrorDomain error 507.) . The appclip works when run via the TestFlight, but not when open via an URL. So it seems the error is at the appClip invocation. Any help to fix the issue is appreciated.

Reply to Supervised devices show wifi setup screen on restart
This behavior still exists in iOS 26.0.1 and iPadOS 26.0.1 even after upgrading the Apple Configurator host to macOS Tahoe 26.0.1. On every restart, Software Update Complete is displayed, along with: Your iPad has been updated to iPadOS 26.0.1. Your iPhone has been updated to iOS 26.0.1. Followed by the Welcome screen with the Get Started button. (Upgrading the Apple Configurator host to macOS Tahoe 26.0.1 did, however, fix the blank Profiles bug in Apple Configurator Version 2.18 10A23.)

UIScene based state restoration on tvOS not working
I can’t get UIScene-based state restoration to work on tvOS as it does on iOS. UISceneSession.stateRestorationActivity is always nil in UIWindowSceneDelegate.scene(_:willConnectTo:options:) despite UIWindowSceneDelegate.stateRestorationActivity(for:) being called in the previous lifecycle. The NSUserActivityType is correctly configured in the Info.plist. Has anyone encountered the same issue or knows how to get this to work?

iOS 26 Voice Over is reporting an extra tab
Feedback number: FB20451665 When building with Xcode 26, Voice Over is reporting an extra tab when swiping through tabs. Please see the sample project below: /* This is a Sample project to show that I believe there is a Voice Over bug in iOS 26. When swiping through tabs with Voice Over active, there always appears to be an extra tab. Here I have 5 tabs, when on tab one VO reads out tab 1 of 6, then tab 2 of 6, all the way to the last tab, when voice over reads out tab 5 of 6. Never tab 6 of 6. Is there a possibility that voice over is picking up the underlying `more` tab and reading that out? This has also been reportedly found in the Files app here: https://www.applevis.com/comment/195441#comment-195441 */ struct ContentView: View { var body: some View { TabView { /// Activating this has Voice over telling us there are 6 Tabs.
