SwiftUI preview hangs on "Preparing iPhone Simulator for Previews". Also simulator hangs when trying to build and run. This occurred after I installed iOS 17 simulator. I tried reverting back to an iOS 16 version of the simulator, but haven't figured out how to do that. Build and run to an iPhone device works fine. Any ideas would be appreciated. Thanks.

An internal error occurs when executing the xcodebuild -list command targeting a Swift Package.

When I new project is initiated in XCode 16 beta 3, an overall folder is created to contain all the generated content in the Navigator pane . In past XCode version, this main container (under the project name) has always been generated as a group. Is this change by design or a bug? The issue this creates is that the files and folders in this overall Folder can not be repositioned - they remain in ascending alphabetical order. I must convert this initial Folder into a Group by right clicking on the folder name and selecting "Convert to group" which converts the folder to a group. I am then able to reposition files, groups and folders within this group. I don't see anywhere in the XCode documentation where this change in behavior is mentioned. Anyone else having this same issue. I never have understood the difference or use cases for groups vs folders in the xcode Navigator pane.

Really stumped on this issue my team is seeing with the Xcode 16 Beta (both Xcode 16 version 6 and Xcode 16.1). Wondering if anyone was having a similar issue and if this is a bug or something configured incorrectly. Basically, when I go to build settings and search for anything related to "Swift Compiler" nothing shows up. The only thing that appears with "Swift" in the title is under the User Defined keys (see attached) As such, I'm unable to change the Swift version for the project and I'm stuck in Swift 6 language mode which we're not quite ready for yet. This is only occurring on one of our targets. Our other app projects are behaving as expected. The project in question has the main target we build the project with and 2 support frameworks. The supporting frameworks are also working correctly. Its just the primary build target giving us fits. Curious if anyone is seeing something similar or has suggestions. Thanks!

Several app developers are struggling with the inability to provide a separate app icons that looks nice on older macOS versions while at the same time provide Icon Composer icons that look great on macOS Tahoe 26. An ability to provide separate icons is super important to those who have app icons that follow the curvature of the default icon borders (as the corner rounding radius is different for Sequia and Tahoe). Take a look at this for example: https://github.com/ghostty-org/ghostty/issues/7564#issuecomment-3042061547 Question: Is there a definitive/recommended way to address this issue? How can a developer add a glass icon variant that looks good on Tahoe and provide a bitmap icon for older macOS versions? Some background info: Prior to Xcode 26 beta 4, one could add an App Icon to Assets to be used as app icon for legacy macOS versions (Sequia and older) and use a new Icon Composer icon (placed in the project root) for macOS Tahoe 26. Enabling "Include all app icon assets" under target settings ensured that older macOS versions would use the old app icons while Tahoe the new Icon Composer glass one. Since Xcode beta 4 this technique no longer works. Xcode instead insists on populating Assets.car with Icon Composer generated variants, disregarding the App Icon provided in Assets. Although the App Icon in Assets makes its way to a .incs file in the app bundle's Contents/Resources folder, but that is not used by macOS anymore and is there for some compatibility purposes. The Assets.car file (which matters) only contains the variants generated by Icon Composer and does not contain the png icons provided in the Assets.

I'm using xcode 16 with swift. I'm trying to call a function in another file. It used to work. Now I'm getting: Cannot find 'detailline' in scope. Detailline is the function I'm calling. I just added variables to the top. I have since deleted them. Please help.

I just swapped over to Xcode 16 and archived my build. I have ENABLE_BITCODE = NO in my Build settings (it's listed under user defined settings). When I go to validate the build, I get a failure "Invalid Executable, ***.framework contains bitcode". Nothing about my project settings has changed. If i swap back to Xcode 15 everything's fine when I validate. One thing I noticed though is that if I go through the process of validating, on the confirmation screen for Xcode 16 RC, the line about Bitcode: Not included does not exist like it does if I hit the confirmation screen in Xcode 15.

We have some third-party SDKs do not support arm64 simulator, so we excluded arm64 for Any iOS Simulator SDK in Excluded Architectures. But in this case, ASWebAuthenticationSession will display abnormally. We submitted FB14853757 during the beta period, but have not received any response. This issue still exists in the official version. I hope it can be resolved. Thank you!

I've recently installed Xcode Version 15.0 (15A240d) and when I set a breakpoint it doesn't stop on the line of code where the breakpoint is set. Rather, it opens another window with the hex code. If I press F6 it doesn't highlight the next line of code, but I can see that it moved because the variables are changing. Is this a known bug? I have tried all the usual stuff like deleting derived data and restarting everything. I have even deleted com.apple.dt.Xcode directory in ~/Library/Caches. to set things back to the defaults. The only thing I haven't done yet is reinstall Xcode. Unfortunately, this is very bad timing as I need to get my app finished for the iOS17 and WatchOS 10 release.

Hello, I have multiple iOS applications using Xcode projects built with Flutter. Originally I created this applications with my Apple ID, however, since then I lost access to my Apple ID's email. I updated my Apple ID email to a new email and now I cannot even build an app locally for the iOS Simulator. I'm on macOS 15 / iOS 18 simulator. Here is the output from xcodebuild: DVTDeveloperAccountManager: Failed to load credentials for [OLD_EMAIL]: Error Domain=DVTDeveloperAccountCredentialsError Code=0 "Invalid credentials in keychain for [OLD_EMAIL], missing Xcode-Token" UserInfo={NSLocalizedDescription=Invalid credentials in keychain for [OLD_EMAIL], missing Xcode-Token} Where OLD_EMAIL is the old Apple ID email. When I go into my Keychain Access app, I remove all references to my old email, but they regenerate when trying to build the app. I've tried doing manually signing on the xcode project config, but that gives the same error as well. This is only on old projects. When I run a new project, I do not have any errors building or uploading to App Store Connect. Any help would be greatly appreciated. Thank you

Hello, do the String Catalogs (new in Xcode 15) support Swift Packages? I've tried adding a new Localizable.xcstrings (string catalog) file to my package's resources folder. Great! I then see this screen: All good so far. I then try to go and build my Swift Package... and nothing changes. The string catalog is never populated and I'm left with the same screen as above. So, do string catalogs not support packages at this time or am I doing something wrong? I was really hoping String Catalogs would work and save the day since Export Localizations also does not work for Swift packages that don't support macOS. 😔

I'm building and running from Xcode 26 to macOS 15.5. On launch, app crashes on start dynamic runtime linking with failure to find _LocationEssentials framework.

Hey Apple Team! We recently updated to Xcode 16 and saw a massive memory spike, which caused "Out of memory" Mac warnings in the final stages of our app's build process. We noticed that the process responsible for this is "EmbeddedBinaryValidationUtility" (see screenshot). Is there a workaround to limit its memory usage? This is causing significant anguish for our developers.

In Xcode 16.0 and 16.1 beta 2, running on macOS 15.1 beta 4, Developer Documentation for Objective-C is (at least partially) missing in the Navigator. Many of the entries appear to be for Swift. In Xcode 16.1 beta (i.e. beta 1), the documentation is normal. I did not find any posts in this forum about this, which is surprising and makes me wonder if the issue is isolated to particular configurations. In any event, I would appreciate any information anyone may have about this.

Whan using a tabview set with a tabviewstyle of sidebaradaptable on macOS 15.1 beta 5 the tabs are non responsive and is basically broken. Example code... If you click around on these tabs you will see it is not responsive. When you add a lot more tabs from a for loop for example you really get poor performance. But this is not the case with earlier beta releases. TabView {                 Tab("One", systemImage: "1.circle.fill") {                     Text("Test One")                 }                 Tab("Two", systemImage: "2.circle.fill") {                     Text("Test Two")                 }                 Tab("Three", systemImage: "3.circle.fill") {                     Text("Test Three")                 }             }             .tabViewStyle(.sidebarAdaptable)

I recently compiled my macOS App with Swift 6 in Xcode 16 (was using Swift 5 previously) and noticed that AppKit Integration doesn't appear to be working as before. All my instances of NSHostingView which allow me to add a SwiftUI View to an AppKit NSWindow view controller no longer respond to mouse input anymore. All my NSHostingView instances display but refuse to accept any user interaction. Has anyone else noticed this and is there a workaround to get NSHostingView to once again be able to accept user/mouse events with Swift 6?

Hi! In neither Xcode 16.2 beta 3 nor Xcode 16.2 I am able to get App Shortcuts Preview to recognise my Shortcuts. In either supported language I always get "No Matching Intent" as the result. Flexible matching is enabled, minimum deployment target is iOS 18. The Shortcut phrases do work in the simulator and on device. Is this a known issue or am I missing something?

Our CI process uses XcodeBuild tools. It used to work very well. The shell code is as follows: step 1 "++++++++++++++++clean++++++++++++++++" xcodebuild clean -workspace ${WORKSPACE_NAME}.xcworkspace \ -scheme ${SCHEME_NAME} \ -configuration ${configuration} step 2 "+++++++++++++++++archive+++++++++++++++++" xcodebuild archive -workspace ${WORKSPACE_NAME}.xcworkspace \ -scheme ${SCHEME_NAME} \ -configuration ${configuration} \ -archivePath ${ARCHIVE_PATH} -allowProvisioningUpdates YES step 3 "+++++++++++++++++ipa+++++++++++++++++" xcodebuild -exportArchive \ -archivePath ${ARCHIVE_PATH} \ -exportPath "${IPA_PATH}" \ -exportOptionsPlist ${EXPORT_METHOD_PLIST_PATH} \ -allowProvisioningUpdates YES However, there is a problem after upgrading Xcode16. When it is executed to the third step, there will be an error in the error account. Even if I delete my developer account, and then log in again, the same error will still be reported.

So I have a MacOS application that was working just fine before Xcode 16. The Widgets are not working anymore. The main application and the widgets share a file in a common App Group. The widget app now get a permission error when accessing the file. Also, the Widget Kit simulator keeps crashing. I also try to start a new project in Xcode, add a target with a Widget extension with an App Intent and run it, and it also crashes. Sometimes, it doesn't crash but just display the error: "Failed to load widget. The operation couldn't be completed. (WidgetKit_Simulator.WidgetDocument.Error error 2.). Edited to attach WidgetKit error log widgetKitError.txt
