View title misaligned after compiling with Xcode 26
After compiling with Xcode 26, my UIKit view's title appears hugging the screen on the left when run on iOS 16-18 (as shown in the image below). It's fine when run on iOS 26, but not older iOS versions. When I compile the same code with Xcode 16.4, the title aligns with the table rows. Has anyone else seen this? Is this a bug in the frameworks or is there something I could do to resolve?

Reply to Validation error, when I try to upload a game to Testflight
Hello @d1bg12 , thank you for your question! The error message you are seeing explains what caused your problem. Validation failed because your icon contains transparent pixels. In other words, your icon needs to be totally solid with no see-through pixels. You can find more information on our documentation page for app icons. For simple icons on iOS, your icon needs to be a non-transparent square image that is 1024x1024 pixels in size. I recommend trying to make the icon yourself in a program like Photoshop or GIMP before relying on a specialized web tool that might not behave the way you expect. The website you linked to is creating an entire image set for you, which you can use for your icons in Xcode, but this is a bit more involved than just supplying a single texture. You can see our documentation page Adding images to your Xcode project for more information. For more complex icons, you can also use Icon Composer to design your icon. Thank you!

Reply to Control status item and login item from within app
I tried before posting, but isVisible stays true even when disabling the status item in System Settings. Hmmm. Please file a bug on that, as you should be able to detect your status. But will the agent be listed in System Settings > General > Login Items? No, it'll be shown immediately below in the section labeled App Background Activity. In my opinion, it would make more sense to use an option that is kept in sync between the app and System Settings. Yes, and that's how this works. SMAppService.status returns the app’s current state in the preference UI. Looking at how different privacy features are implemented in macOS, I would have expected that login items (or agents, or however we might call them) can be disabled in System Settings, without the app being able to turn them on again without the user noticing. Yes, and that's how this works too. If your status is SMAppServiceStatusRequiresApproval, then the user will need to activate the component themselves through the preference UI. Having said that

SwiftUI TextField with lineLimit inside Form does not respect lineLimit.
macos 26, xcode 26, ios 26. Everytime when you add new line at some point (like after 10-20 lines) the TextField will ignore the lineLimit and start changing the height. The problem related to Form but not Scroll. Maybe it can be reproduced in other scroll-based views. Bug report opened. Any siggestions? struct Test: View { @State var text = var body: some View { Form { Section { TextField(, text: $text, axis: .vertical) .lineLimit(3) .background(Color.green) } } } } @main struct TestApp: App { var body: some Scene { WindowGroup { Test() } } }

Reply to Too many mach ports?
I would like to update our metrics for iOS 26 regarding this issue. It appears that the problem persists on iOS 26 and has worsened as the iOS 26 call count has increased. We will keep eyes on our metrics and post update here. Has there been any specific change on iOS 26? That question isn't really answerable. Nothing has really changed here as far as CallKit in concerned, however, the broader audio system involves multiple daemon's that are all basically under constant, active development. So, yes, it's very likely that a change in the audio system is causing this change but that doesn't mean I can point to any specific change that created this issue. __ Kevin Elliott DTS Engineer, CoreOS/Hardware

Reply to AppGroups data loss after App transfer and App update.
A colleague pointed out that I did't quite get the details right here. But, nonetheless the key thing to know is that any app groups created in a previous developer account will not follow an app to a new developer account after an app transfer. Any data stored using an app group created in a previous developer account will not be accessible after an app transfer even if you use the same app group names. Here are the corrected details: App group IDs never start with an App ID prefix. Rather: iOS-style app group IDs start with group. macOS-style app group IDs start with the Team ID. To read more, please see the forums thread App Groups: macOS vs iOS: Working Towards Harmony

Reply to CardSession.Error.maxSessionDurationReached not thrown on iOS 26
We would like a bug report about this to understand why your app is crashing. First, please go to https://developer.apple.com/bug-reporting/profiles-and-logs/ and follow the instructions for CoreNFC and SEC Frameworks for iOS to install a logging profile on your device. Once that is installed, then reproduce the issue. Once reproduced, then follow the instructions at the above link to create a sysdiagnose Please file a Feedback report with the full description and details on what you are seeing not working. Attach the sysdiagnose and the crash logs you are receiving after symbolicating them. You can read Adding identifiable symbol names to a crash report to learn how to symbolicate a crash log. Once done, please respond here with the Feedback ID so we can start investigating. Argun Tekant /  WWDR Engineering / Core Technologies

AKAuthenticationError −7027 when using Sign in with Apple on iOS (Managed Apple ID / Shared iPad environment)
We are working on a PoC iOS App to use Sign in with Apple on iOS. The app needs to authenticate the current user on MDM managed corporate iPads (with Shared iPad enabled) and each user having a Managed Apple ID (created in Apple Business Manager). We have started with Apple's example app: https://developer.apple.com/documentation/authenticationservices/implementing-user-authentication-with-sign-in-with-apple When we run it on a normal iPad (without MDM supervision) it works fine. When we run the same code on a managed iPad with Shared iPad enabled and Managed Apple ID's the app errors out when a user taps the Sign in with Apple button. A User-facing error message is displayed: “Your Apple Account cannot be used to create accounts for other apps.” And when we run the app from Xcode we see the following logs: Authorization failed: Error Domain=AKAuthenticationError Code=-7027 (null) UserInfo={AKClientBundleID=com.sampleapp.test2} LaunchServices: store (null) or url (null) was nil: Error Domain

10-bit support in iPad Pro
Hi, I’m using the latest iPad Pro (13-inch) and I can see that Metal offers an rgb10a2unorm texture for rendering, but when I render a grey ramp and measure the actual luminance, I get a pattern that I would expect from an 8-bit texture (see below). Before I start ripping apart all my code, is there anything else I need to do to convince iOS to render my texture in 10-bit? I already tried setting the PixelFormat in my CMetalLayer to rgb10a2unorm, but that didn’t change anything.

Error saving image to Camera Roll on iPhone 17 Pro
I'm experiencing an issue with my app when saving images to the camera roll. This is intermittent, but it happens several times a day.
