CRITICAL: iOS 26.1 Simulator Runtime (Build 23B86) Missing / MobileAsset Catalog Failing Summary After updating macOS and Xcode, I can no longer download or install the required iOS 26.1 simulator runtime.

I created in my Objective-c project the AgeRange check for a special function. It is working well on an iPhone. Now I used my Mac and added my app to the TestFlight on my macOS Tahoe 26.1 Here it is directly crashing. But how can I debug an Application which is created for iPhone and iPad with Xcode? I cannot use the target myMac when running a debugging mode. So how is the debugging working for such Apps?
Hello! I have requested multiple issues on https://developer.apple.com/contact/ (it has been over two weeks now requesting an update with a valid DUNS number), yet they have not even emailed me anything. I am trying to convert my developer account from individual to team, so my other team members can render the app on Xcode even when Appled ID login is in place in the app (currently, they can't compile the app with the individual developer account). I would just like to have my account be updated from individual to organization. I have also tried many times on https://developer.apple.com/contact/request/migrate-individual-account/

When I run the following code and change Is On, I get a problem with the layout of the Picker. There is no problem when using Text(), but when using only Image, it works fine on iOS but there is a problem on macOS. Tested on macOS 26.1, Xcode 26.1. import SwiftUI struct ContentView: View { @State var model = Model() var body: some View { Form { Picker(Category, selection: $model.category) { ForEach(Category.allCases) { item in Image(systemName: item.icon) .tag(item) } } .pickerStyle(.segmented) Toggle(Is On, isOn: $model.isOn) } .formStyle(.grouped) } } struct Model { var category: Category = .a var isOn: Bool = false } enum Category: Int, Identifiable, CaseIterable { case a, b, c var id: Int { rawValue } var icon: String { switch self { case .a: return a.circle.fill case .b: return b.circle.fill case .c: return c.circle.fill } } var name: String { switch self { case .a: return a case .b: return b case .c: return c } } } code-block
[quote='866301022, DTS Engineer, /thread/807446?answerId=866301022#866301022'] I would recommend to go to the App Store and download the latest Xcode available. [/quote] Right. But if you want a specific old version of Xcode, you can get that from Developer > Downloads. Click More (at the top right) get to the archive, where you’ll find Xcode 15.2 and many others.

I've mistakenly created that diagnosis report just after a reinstallation of the OS, but the Xcode example (or any other Finder Sync Extension) was not running yet on that machine. I've uploaded a new report which now should correctly contain everything with the Xcode example. Event the reinstallation of the OS did not help.

Thank you for your follow-up and guidance. I have tested this again on iOS 26.1 with Xcode 26.1.1 and can confirm the issue still reproduces as described: Building the project with Xcode 26.1.1 and running on an iOS 26.1 device results in the share extension showing an opaque white sheet background instead of the expected transparent or glass effect. To assist with your investigation, I have uploaded the sample project and included a video demonstrating the issue.

I appreciate your time in reviewing this and am happy to provide further information if needed.

I refuse to believe they didn’t test it before, so I can only assume they don’t care. It’s crazy, but it looks like every other Xcode version ships with a broken debugger. In some versions, it works better, but then the next one arrives with a broken debugger. Beside Wi-Fi issues, the debugger sometimes gets stuck, fails to debug async code, and so on. This forum is full of debugger bugs, it makes me wonder which debugger they use to debug the internal apps.

I take that back. the Share Extension seems to be working properly (as far as I can tell) when built with Xcode 26.1.1, running on iOS 26.1 Thanks to all who made that possible!

In my case, building with Xcode 26.0 or 26.1.1, the share extension fails to open the destination app. Doesn't crash. Just doesn't work. Same Share Extension code works fine when built with Xcode 16.4. I'd have thought that the ability to share files across apps on iOS would be an absolutely critical part of the system, and would have been a top priority to fix quickly, but appears to be still broken in Xcode 26.1.1 Any new developments / fixes?

Getting a flurry of these warnings at the top of my macOS/Xcode 26.0 and 26.1 builds (200 lines). These did not occur prior. These are Apple system menus that are in the Storyboard that have been there forever.

The fact that it's not supported on Simulator is annoying. What an inconvenience. Is this going to change soon? I'm on Xcode 26.1 and Simulator iOS 26.1.
