An app with a UIToolbar pinned to the bottom of a view controllers view extends to the screen edge (behind the safe area) when run on iOS 18.X but not iOS 26. This UIToolbar is set as constrained to the safeAreaLayoutGuide with the following constraints. self.view.addConstraints([ bottomToolbar.leadingAnchor.constraint(equalTo: self.view.leadingAnchor), bottomToolbar.trailingAnchor.constraint(equalTo: self.view.trailingAnchor), bottomToolbar.bottomAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.bottomAnchor), bottomToolbar.heightAnchor.constraint(greaterThanOrEqualToConstant: 44.0) ]) This is especially noticeable when the UIToolbar background color differs from the view background color. This occurs on iOS 26 beta 6, app built with Xcode 26 beta 5. I've posted a Feedback FB19664903 including a minimal Xcode workspace that reproduces this issue. Anyone suggestions would be appreciated ... this definitely seems like a regression.

A UISegmentedControl as a UIBarButtonItem (customView) is ignoring selectedSegmentTintColor on iOS 26, works fine on prior versions I've submitted FB19660941 with a minimal Xcode workspace to reproduce the issue. Has anyone else seen this and identified a workaround?

An iOS app has a UINavigationController with a UINavigationBar that is non-translucent (e.g. black). When performing a push (or pop) to navigate to or from another UIViewController the UIBarButtonItems on the navigation bar are flashing a white background. With a dark navigation bar this is very noticeable and not desirable. This only occurs when run on iOS 26 and is related to Liquid Glass I've created FB19660024 with a minimal Xcode workspace to reproduce, along with a video showing the behavior. This is a cosmetic bug, not affecting functionality, but is a very undesirable effect on apps with dark and non-translucent navigation bars. Has anyone else seen this and found a workaround?

My app does really large uploads. Like several GB. We use the AWS SDK to upload to S3. It seemed like using BGContinuedProcessingTask to complete a set of uploads for a particular item may improve UX as well as performance and reliability. When I tried to get BGContinuedProcessingTask working with the AWS SDK I found that the task would fail after maybe 30 seconds. It looked like this was because the app stopped receiving updates from the AWS upload and the task wants consistent updates. The AWS SDK always uses a background URLSession and this is not configurable. I understand the background URLSession runs in a separate process from the app and maybe that is why progress updates did not continue when the app was in the background. Is it expected that BGContinuedProcessingTask and background URLSession are not really compatible? It would not be shocking since they are 2 separate background APIs. Would the Apple recommendation be to use a normal URLSession for this, in which case AWS would need to change their SDK? Or does Apple think that BGContinuedProcessingTask should just not be used with uploads? In other words use an upload specific API. Thanks!

This example application crashes when entering any text to the token field with FAULT: NSGenericException: The window has been marked as needing another Update Constraints in Window pass, but it has already had more Update Constraints in Window passes than there are views in the window. The app uses controlTextDidChange to update a live preview where it accesses the objectValue of the token field. If one character is entered, it also looks like the NSTokenFieldDelegate methods tokenField(_:styleForRepresentedObject:) tokenField(_:editingStringForRepresentedObject:) tokenField(_:representedObjectForEditing:) are called more than 10000 times until the example app crashes on macOS Tahoe 26 beta 6. I've reported this issue with beta 1 as FB18088608, but haven't heard back so far. I have multiple occurrences of this issue in my app, which is working fine on previous versions of macOS. I haven't found a workaround yet, and I’m getting anxious of this issue persisting into the official release.

The command line interface for diskutil is missing the snapshot features there is now no way to take a custom snapshot of a volume and mount it. tmutil doesn’t not allow the flexibility of diskutil when doing research. Please restore this functionality. feedback id: FB19590860

I’m seeing an issue with subscriptions in TestFlight builds on iOS 26. Running from Xcode works as expected, and the App Store build looks fine. But when I install the same build via TestFlight, transaction.subscriptionStatus is nil. The identical binary behaves correctly on an iOS 18 device. Is this expected behavior on iOS 26 TestFlight, or am I missing something? Thanks!

I know you guys probably dont care or what to help with this but I got taken down in the support communities because I simply run a beta version (didn’t even discuss it) but here we go **My MacBook Air has multiple accounts and the other users & shared category takes up 100+ gb. When I sign into one of the accounts, that 100+ gb gets moved to System Data. When I look in finder, the user only seems to take up 12 gb, though. I’ve shown hidden items and looked through the library, but it’s not showing anything that’s taking up that much space! **

When I try to install the iOS 26.0 Universal Simulator component with Xcode-beta 5 I get the following error: Download failed.

If I compile a compute kernel with a call to texture.read(), it fails with the following error: "Error Domain=AGXMetalG13X Code=3 "Encountered unlowered function call to air.get_read_sampler" UserInfo={NSLocalizedDescription=Encountered unlowered function call to air.get_read_sampler}." This error occurs on both macOS and iOS 26 Beta 5, but not when running on a simulator or in a playground. It does not occur on a macOS Sequoia VM. It occurs whether I use the old metal 3 or new metal 4 compilation method. A workaround would be to use a sampler, but according to the feature tables, all platforms support reading from textures of all formats. Below is a minimal example which produces the error: let device = MTLCreateSystemDefaultDevice()! let library = device.makeDefaultLibrary()! let computeFunction = library.makeFunction(name: "compute_test")! do { let pipeline = try device.makeComputePipelineState(function: computeFunction) debugPrint(pipeline) } catch { debugPrint("Metal 3 failed with error:\n\(error)") } #import <metal_stdlib> using namespace metal; kernel void compute_test(uint2 gid [[thread_position_in_grid]], texture2d<float, access::read> in [[texture(0)]], texture2d<float, access::write> out [[texture(1)]]) { out.write(in.read(gid), gid); } I filed feedback FB19530049.

I was testing audio playback from YouTube in Safari, and the sound was clipping heavily. At first, I thought it might be due to the poor quality of my small sound system. However, when I took a screenshot and the screenshot sound effect itself produced a loud clipping noise, it became clear that this is not a mechanical problem with my speakers, nor an issue specific to YouTube or Safari. This appears to be a system-wide audio issue in macOS Tahoe 26 - Beta 5.

I'm trying to download mods for Stardew Valley, before the beta it worked but now it doesn't. Is there anyone who can help to fix this? Used Firefox and Safari as well as Safari on my ipad.

I have been experimenting with the BGContinuedProcessingTask API recently (and published sample code for it https://github.com/infinitepower18/BGContinuedProcessingTaskDemo) I have noticed that if I lock the phone, the code that runs as part of the task stops executing. My sample code simply updates the progress each second until it gets to 100, so it should be completed in 1 minute 40 seconds. However, after locking the phone and checking the lock screen a few seconds later the progress indicator was in the same position as before I locked it. If I leave the phone locked for several minutes and check the lock screen the live activity says "Task failed". I haven't seen anything in the documentation regarding execution of tasks while the phone is locked. So I'm a bit confused if I encountered an iOS bug here?

I have a custom VPN app that uses NETunnelProviderManager to install a VPN Profile if one is not already installed. On previous iOS versions this would open the VPN Settings and ask for either the PIN, FaceID or TouchID and install the profile. With iOS 26 beta5 it opens the VPN Settings and stops. Is this a bug in iOS 26? Have there been changes to NETunnelProviderManager for iOS 26 that I'm not aware of? FYI we do the samething on macOS 26 beta5 and that works as expected.

Using the official SwiftTranscriptionSampleApp from WWDC 2025, speech transcription takes 14+ seconds from audio input to first result, making it unusable for real-time applications. Environment iOS: 26.0 Beta Xcode: Beta 5 Device: iPhone 16 pro Sample App: Official Apple SwiftTranscriptionSampleApp from WWDC 2025 Configuration Tested Locale: en-US (properly allocated with AssetInventory.allocate(locale:)) and es-ES Setup: All optimizations applied (preheating, high priority, model retention) I started testing in my own app to replace SFSpeech API and include speech detection but after long fights with documentation (this part is quite terrible TBH) I tested the example (https://developer.apple.com/documentation/speech/bringing-advanced-speech-to-text-capabilities-to-your-app) and saw same results. I added some logs to check the specific time: 🎙️ [20:30:41.532] ✅ Analyzer started successfully - ready to receive audio! 🎙️ [20:30:41.532] Listening for transcription results... 🎙️ [20:30:56.342] 🚀 FIRST TRANSCRIPTION RESULT after 14.810s: 'Hello' (isFinal: false) Questions Is this expected performance for iOS 26 Beta, because old SFSpeech is far faster? Are there additional optimization steps for SpeechTranscriber? Should we expect significant performance improvements in later betas?

I successfully installed macOS Tahoe 26 in June on a separate external partition. Now I want to update to beta 5, but when the Mac restarts to install the update, it shows the progress indicator for a minute or two, then boots again into the main partition which has macOS 15.6. Am I required to install it from scratch?
