App can't debug on iOS 26 device, but can on iOS 18
This is from Mac OS 26 or the prior version. It seems to be trying to include XCTest, but its no where in the build phases or frameworks? Anyone seen this issue?

Xcode26: download stuck on 'fetching'
I just downloaded Xcode26, and am trying to download the new simulator to be able to run and test my app. But the downloads folder just shows that it's stuck on "Fetching download information ..." even 15 minutes after it started. I tried restarting Xcode but didn't help. Internet connection is good. Any tips to get it working?

The async/await API crashes in Xcode 16.3 and later
We use several UIKit and AVFoundation APIs in our project, including: setAlternateIconName(_:completionHandler:) getAllTasks(completionHandler:) loadMediaSelectionGroup(for:completionHandler:) Moreover, we use the Swift Concurrency versions for these APIs: @MainActor func setAlternateIconName(_ alternateIconName: String?) async throws var allTasks: [URLSessionTask] { get async } func loadMediaSelectionGroup(for mediaCharacteristic: AVMediaCharacteristic) async throws -> AVMediaSelectionGroup? Everything worked well with these APIs in Xcode 16.2 and earlier, but starting from Xcode 16.3 (and in 16.4), they cause crashes. We've rewritten the APIs to use completion blocks instead of async/await, and this approach works. Stack traces: setAlternateIconName(_:completionHandler:) var allTasks: [URLSessionTask] { get async } loadMediaSelectionGroup(for:completionHandler:) Also, I attached some screenshots from Xcode 16.4.

File download not working in Xcode 26.0 RC
Hello Apple Developer Community, I'm experiencing an issue with file download functionality in the iOS Simulator after updating to Xcode 26 RC (Build 17A321). Issue Description: When attempting to download files in the iOS Simulator via Safari, the download prompt appears correctly, but after tapping the 'Download' button, files are not being saved to the Files app. The download appears to do nothing with no error message, no indication of failure, but the file simply doesn't appear in Downloads or anywhere in the Files app. Environment: Xcode Version: 26.0 RC (17A321) iOS Simulator Version: 26.0 RC (23A339) Device Simulated: iPhone Air Steps to Reproduce: Open Safari in the iOS Simulator Navigate to a downloadable file (PDF, ZIP, etc.) Tap to initiate download Download prompt appears as expected Tap the 'Download' button Check the Files app → Downloads folder (empty) Expected Behavior: Files should download normally as they do on physical devices and as they did in previous Xcode versions. Actual Behavior: The download prompt dismisses after tapping 'Download', but no file appears in the Files app. No error message is shown, and there's no indication that the download failed, it simply appears as if nothing happened. Additional Information: Downloads work correctly on physical device (iOS 26 RC 23A340) This functionality worked properly in previous Xcode versions I have created a bug report to Feedback assistant: FB20190927 Thanks in advance for any assistance.

Simulator frozen while Xcode debugger attached
I'm on Xcode 16.3 (16E140), using iPhone 16 Pro Simulator with iOS 18.4, on macOS Sequoia 15.4. Today is the first time using this particular configuration. On Friday I was using Xcode 16.2, simulator on 17.5, macOS 15.3.2. This morning while running the app in the debugger I get times where I pause in using the app, perhaps to look up some information or make some notes, then go back to the simulator and nothing works. It is just frozen. Tap tap tap all day long and nothing responds. In the Xcode console I get this over and over while the simulator doesn't respond. nw_protocol_socket_set_no_wake_from_sleep [C100.1.1:2] setsockopt SO_NOWAKEFROMSLEEP failed [22: Invalid argument] nw_protocol_socket_set_no_wake_from_sleep setsockopt SO_NOWAKEFROMSLEEP failed [22: Invalid argument] I then hit the "Stop" button in Xcode debugger and get this in console <0x10843a0b0> Gesture: System gesture gate timed out. XPC connection interrupted Message from debugger: Xcode has killed the LLDB RPC server to allow the debugger to detach from your process. You may need to manually terminate your process. The Simulator springs to life immediately. It even seems to have queued up my most recent inputs and happily accepts them and processes them as normal.

Xcode 26 beta 3 - Metal toolchain installed but not working
Under Xcode 26 beta 3 I'm trying to build a project which uses Metal. I've installed the Metal Toolchain 26.0 under Settings -> Components, but when I start a build it fails during the "Prepare build" step with the following error (repeated many times): stat(/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.1.5276.7.Pb9SLL/Metal.xctoolchain/usr/bin/clang): No such file or directory (2) I've confirmed that there is in fact no 'clang' binary in that directory. I've tried using xcode-select to set the Xcode 26 Beta app as the active developer directory, and xcodebuild -version shows: Xcode 26.0 Build version 17A5276g Any ideas on other things to try?
