From last week all crash for watchOS has been broken. The latest version 15.22.1 missing all stack trace and showing weird as attached. All the crashes for previous versions totally disappeared.

I'm trying to compile my project, which worked fine before upgrading to Xcode 16, and I'm getting error clang: error: unsupported option '-mno-thumb' for target 'arm64-apple-ios18.0-simulator'. It appears to a similar issue as this BoringSSL-GRPC issue. The fix from StackOverflow was to automatically strip the flag in the Podfile using CocoaPods, but I'm not using CocoaPods. I've grepped the entire project, and I can't find that flag anywhere in the project. Likewise, the full error message doesn't even include -mno-thumb. Does anyone know how I can determine where this flag is being added, so I can remove it? I've tried this in both Xcode 16.1 and Xcode 16.2 on MacOS Sonoma and Sequoia 15.2.

I can't add my iPhone to my Apple Developer team, even though my iPhone is properly connected to my Mac.

Trying to use SwiftUI Preview in Xcode 16.2 on complex project, I have no access to Developer Apple team, instead I am using manually installed provision profiles to test on iPhone. So, SwiftUI Preview does not work with diagnostic error "Failure: Framework Agent preparation failed: Could not find a team ID"

In my Mac's Settings -> General -> Storage -> Developer -> (i) I have a series of entries for "bridgeOS", all 2.49 GB except one that is "zero". Do I need these? Can I remove them? I am only doing "normal" iPhone / iPad development. (There was some previous mention of this here: https://developer.apple.com/forums/thread/711279 with no feedback.)

In my Swift app, Xcode has decided to put various important settings like, SWIFT_VERSION under "User Defined." Does anyone know why?

I have a project that imports SPM swift-navigation which in-turn imports SPM https://github.com/pointfreeco/swift-perception I have a test target it builds and runs with no issues in XCode however if I run with xcodebuild i get the below error (I have done basics removed derived data etc.) ❌ error: Build input file cannot be found: '/Users/chris/mtp-iOS-retail-iPhone/build/Build/Products/Debug/PerceptionMacros'. Did you forget to declare this file as an output of a script phase or custom build rule which produces it? (in target 'Perception' from project 'swift-perception')

Hello, I am doing the SwiftUI tutorial with Xcode 16.2 For the watch app the simulator working fine but the preview keep saying “This app cannot run on the selected target device.” while the preview is working …… For the macOS part the simulator working fine but the preview is totally broken with -> ”ContentView.swift” not found in any targets. While it is correctly added to the target … Please fix or make tutorial clear.

When I run a program on my iPhone through xcode, and turn off the network，xcode will break the link。I connected my iPhone by USB-C line。

iOS simulator way slower to launch after updating to Xcode Version 16.2 (16C5032a). macOS 15.3.1 (24D70) MacBook Air M1, 8GB

After upgrading to XCode 16.2, I am not able to see apple watch in xcode. I was able to see in XCode 15.2.

I have the 'warnings as errors' policy set to Yes for Apple Clang and Swift compiler. As far as I know, there is no way to make exceptions to the warning policies from Swift compiler (correct me if I am wrong), what about Clang warning policies, specifically when it comes to header files from 3rd party pods? They don't show up on the Compile Sources so I can't apply flags such as -Wno-error=deprecated to them. Adding #pragma GCC... to them won't help as a fresh pod install will wipe the #pragma statements out. Is there a way to exclude the header files from pods from getting the warning policies from Clang so I won't see errors from them when compiling Clang modules that's a part of the build process?

Hello Everyone, Planning to add one Devoloper to my team for Xcode app development. whats best to configure Xcloud ,Git and push updates to the main branches . and i prefer not to use third party software or additional tools . Thanks a lot and much appreciated

I am trying to update the EditButton after deleting rows in a List, but its title doesn't change. I have sent an update event via a publisher that applies the mode change based on the number of items remaining in the list. Here's the update event handler: .onReceive(updateViewPublisher, perform: { _ in self.editMode?.wrappedValue = textFileData.textFiles.count == 0 ? .inactive : .active update += 1 })``` The edit mode is changed to inactive when the list is empty, but the button continues to display 'done'. If I adda new list item it remains set to 'done' and the delete control is displayed against the new item. I have seen loads of posts about this on various sites, but no solutions. I am trying this on Xcode 16.2 and IOS 18.2. If someone from Apple sees this, a reply would be most welcome.

After updating Xcode my app stoped running on real device

Hello! When trying to use MLTensor, I am getting the error that it is not found in scope even though I am using Xcode 15.1 (it says fully up to date) and set my deployment target to iOS 17.2. Is there something else I need to be doing in order to use MLTensor? Thanks! Michael

I'm trying to use Xcode UI tests for the first time. I added a UI Tests target and set up the signing, then opened the default AppnameUITests.swift file. I added a new function named testAboutPage(), clicked inside the block and clicked the Record UI Test button (red circle) at the bottom of the editor window. If the app is already running when I do this, Xcode crashes immediately. If the app is not running, Xcode builds and runs the app, then crashes. I've seen reports of this going back years, but none of the posts have a solution. I do have a crash log to share. Does anyone know how to get past this? This forum won't let me upload the complete crash log because it exceeds the size limit, but here's the first part through the stack trace of the crashed thread: Process: Xcode [46652] Path: /Applications/Xcode.app/Contents/MacOS/Xcode Identifier: com.apple.dt.Xcode Version: 16.2 (23507) Build Info: IDEApplication-23507000000000000~2 (16C5032a) App Item ID: 497799835 App External ID: 870964517 Code Type: ARM-64 (Native) Parent Process: launchd [1] User ID: 503 Date/Time: 2025-02-04 12:58:05.5200 -0800 OS Version: macOS 15.3 (24D60) Report Version: 12 Anonymous UUID: 144B0B99-8D44-736B-0D9A-1F6FA6DF85F7 Time Awake Since Boot: 48000 seconds System Integrity Protection: enabled Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: Namespace SIGNAL, Code 6 Abort trap: 6 Terminating Process: Xcode [46652] Application Specific Information: abort() called Application Specific Signatures: ((result)) != nil Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 libsystem_kernel.dylib 0x18a3b3720 __pthread_kill + 8 1 libsystem_pthread.dylib 0x18a3ebf70 pthread_kill + 288 2 libsystem_c.dylib 0x18a2f8908 abort + 128 3 IDEKit 0x109e81554 +[IDEAssertionHandler _handleAssertionWithLogString:assertionSignature:assertionReason:extraBacktrace:] + 964 4 IDEKit 0x109e819e4 -[IDEAssertionHandler handleFailureInMethod:object:fileName:lineNumber:assertionSignature:messageFormat:arguments:] + 876 5 DVTFoundation 0x10600d358 _DVTAssertionHandler + 424 6 DVTFoundation 0x10600d4d8 _DVTAssertionFailureHandler + 196 7 IDEKit 0x10a1f99e4 -[IDEUIRecordingManager _workspaceTabController] + 176 8 IDEKit 0x10a1fa528 __94-[IDEUIRecordingManager _startRecordingWithLaunchSession:alwaysAskForAPIAccess:reservedNames:]_block_invoke_3 + 252 9 DVTFoundation 0x10611fc9c __DVT_CALLING_CLIENT_BLOCK__ + 16 10 DVTFoundation 0x1061206c4 __DVTDispatchAsync_block_invoke + 152 11 libdispatch.dylib 0x18a237854 _dispatch_call_block_and_release + 32 12 libdispatch.dylib 0x18a2395b4 _dispatch_client_callout + 20 13 libdispatch.dylib 0x18a248040 _dispatch_main_queue_drain + 984 14 libdispatch.dylib 0x18a247c58 _dispatch_main_queue_callback_4CF + 44 15 CoreFoundation 0x18a5139d0 __CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE__ + 16 16 CoreFoundation 0x18a4d35bc __CFRunLoopRun + 1996 17 CoreFoundation 0x18a4d2734 CFRunLoopRunSpecific + 588 18 HIToolbox 0x195a41530 RunCurrentEventLoopInMode + 292 19 HIToolbox 0x195a47348 ReceiveNextEventCommon + 676 20 HIToolbox 0x195a47508 _BlockUntilNextEventMatchingListInModeWithFilter + 76 21 AppKit 0x18e04a848 _DPSNextEvent + 660 22 AppKit 0x18e9b0c24 -[NSApplication(NSEventRouting) _nextEventMatchingEventMask:untilDate:inMode:dequeue:] + 688 23 AppKit 0x18e03d874 -[NSApplication run] + 480 24 IDEKit 0x109e50f14 -[IDEApplication run] + 192 25 AppKit 0x18e014068 NSApplicationMain + 888 26 dyld 0x18a06c274 start + 2840

They said something like hold option or whatever but It didn't seems to work with me...
