ERROR: Unrecognized attribute string flag '?' in attribute string "T@"NSString",?,R,C" for property debugDescription
Hello, I'm seeing many errors like this in the Xcode debug console when I build and run my app: ERROR: Unrecognized attribute string flag '?' in attribute string "T@"NSString",?,R,C" for property debugDescription The app project makes heavy use of Logger(), and I suspect it is related to that logging in some way, but I haven't been able to narrow down the issue to specific log calls. I have Category, Subsystem and Timestamp enabled in the Xcode console, but none of those are displayed for this output. What causes this? Or how can I better narrow down the source?

Can't renew, can't update contact info
I originally created my Apple Developer account when I was living in Canada (years ago). Now that I live in the U.S. I want to renew it, but I can't - because it thinks I'm still in Canada. When I go to change my contact information, I get a screen that says: "Unauthorized Your account can’t access this page. There may be certain requirements to view this content. If you’re a member of a developer program, make sure your Account Holder has agreed the latest license agreement." What do I do?

What exactly an Xcode framework does?
I created 2 iOS projects in Xcode: Project 1: 4 targets (main app + 3 app extensions) 4 static libraries the main app's target dependencies include - 3 app extensions and the 4 libs. the main app's binary is linked to all 4 libs similarly, each extension is linked to all 4 libs Project 2: 5 targets (main app + 3 app extensions + 1 framework) 4 static libraries the main app's target dependencies include - 3 app extensions and the framework each extension is dependent only on the framework the framework's target dependencies include all the 4 static libs As per my understanding, the app bundle size for Project 2 should be less than that of Project 1, since we eliminate duplicating the static libs for each target by using a framework instead. However, I have found that the bundle size is more for Project 2 as compared to the bundle size of project 1. I do not understand, why?

FileProvider fails to trigger re-enumeration
I'm working on a FileProvider which allows access to encrypted files in Dropbox; I can successfully read and present the decrypted files, so I know it's basically working. But I'm having problems getting FileProvider to re-enumerate a folder when its encryption status changes. When the FileProvider receives an update notification saying a folder is now encrypted, I use signalEnumerator to re-enumerate the folder: FileProviderExtension.manager?.signalEnumerator(for: existingItem.itemIdentifier, completionHandler: { (ourError : Error?) -> Void in       if let ourError = ourError {           log("notifyCallback: mount / unmount failed re-enumeration: \(ourError)")       } else {           log("notifyCallback: mount / unmount signalled re-enumeration; pending")       } }) The log reports that the re-enumeration is pending... but as far as I can tell, neither enumerateItems nor enumerateChanges is called on the folder's item unless a Finder window is actually open for that folder. This means that, when an app other than Finder tries to access the files through the filesystem, it doesn't see the updated set of filenames. (For further reference: I've added code to both enumerateItems and enumerateChanges, so that if the call has been triggered by a recent folder-encryption notification, it retrieves a complete set of items from the Dropbox folder. If a retrieved file has an encrypted filename, it reports it as a modified item and returns its filename in-clear; if the filename isn't encrypted, it doesn't return the item (for enumerateItems) or returns it as a deleted item (for enumerateChanges). This approach seems to work successfully for listing folders with a constant state; it's only if the user encrypts / decrypts a folder without currently having a Finder window open inside that folder that I'm not seeing a refresh.) Any advice on how I can force a re-enumeration without a Finder window currently being displayed?

Xcode 26 beta 5 - actool version decode error killing CI builds
Getting a weird build failure with Xcode 26 beta 5 that I haven't seen before. Build works fine locally but fails in CI when building with xcodebuild with this error: build description signature: 7cb0bf47dd6decc14090f5ae23d66594 Build description path: /Users/user/Library/Developer/Xcode/DerivedData/ProjectName-dpklhpaqruhpwdbkihszqtqogzfb/Build/Intermediates.noindex/XCBuildData/7cb0bf47dd6decc14090f5ae23d66594.xcbuilddata error: Failed to decode version info for '/Applications/Xcode-beta.app/Contents/Developer/usr/bin/actool': The data couldn’t be read because it is missing.

This error repeats like 15 times in the build log. Build command: set -o pipefail && xcodebuild -workspace "ProjectName/ProjectName.xcworkspace" -scheme "ProjectNameDeviceTests" -configuration "Debug" -destination "generic/platform=iOS" -resultBundlePath "Build for device/result_bundle.xcresult" -verbose TREAT_WARNINGS_AS_ERRORS=YES COMPILER_INDEX_STORE_ENABLE=NO -IDEBuildLocationStyle=Custom -IDECustomBuildLocationType=Absolute -IDECustomBuildProductsPath="$PWD/test_package" OTHER_SWIFT_FLAGS='${inherited} -Xfrontend -debug-time-function-bodies -Xfrontend -debug-time-expression-type-checking' SWIFT_COMPILATION_MODE=wholemodule clean build-for-testing The issue seems to come and go, sometimes cleaning the derived data and/or reset helps, sometimes it doesn't. Anyone else hitting this? Seems like a parsing bug in the beta where it can't read its own version info properly.

How to refresh local Swift Package after adding files in Xcode 16?
Since upgrading to Xcode 16, I've noticed that when I add new files to my local Swift packages, the "Update Package" option is no longer available when I right-click on my local package. In previous versions of Xcode, I used this feature to make Xcode recognize newly added files without any issues. Now, with Xcode 16, the only way I've found to get Xcode to recognize new files is to remove and re-add the entire package, which is obviously not ideal. I've tried cleaning the build folder and rebuilding the project, but it doesn't seem to help. Is there a new workflow or method in Xcode 16 to refresh or update local Swift packages without needing to remove and re-add them every time? Any suggestions or workarounds would be greatly appreciated! What I’ve tried so far: Cleaning and rebuilding the project Looking for any options under "File > Packages" menu Environment: Xcode 16 Local Swift Package Thanks in advance!

It takes a long time to create a developer account as a company.
We registered as a developer company (NGO) more than 50 days ago and it's still under review. We've already sent the documents, we've confirmed by phone, and every time we contact them we receive no information. They just tell us it's under review and there's no deadline for when this review will be completed. On the same day we registered with Apple, we registered with Google and our app has been published on Google for more than 30 days. We have no support or answers. Could someone help us to at least know a deadline for this review?

Random exportArchive 70 Error Code When Using Xcode Cloud for Build
Recently, I’ve noticed that the Archive workflow on Xcode Cloud frequently fails randomly with the following error: ❌ Exporting for App Store Distribution failed. Please download the logs artifact for more information I’m not sure if this issue is on my side or if it’s related to Xcode Cloud itself. Has anyone encountered a similar problem?

Xcode 16.2 Framework Signing Issues with Cloud Managed Developer ID in Automated Builds
Xcode 16.2 Framework Signing Issues with Cloud Managed Developer ID in Automated Builds Issue Description After upgrading from Xcode 15.4 to 16.2, our macOS app's frameworks are failing notarization with the error "The binary is not signed with a valid Developer ID certificate" for embedded frameworks when building through fastlane. This worked correctly in Xcode 15.4. Importantly, manually archiving and notarizing through the Xcode GUI still works correctly - the issue only occurs during automated builds. Build Configuration We use fastlane to build and notarize our macOS app: build_mac_app( scheme: 'Runner', export_method: "developer-id", xcargs: '-allowProvisioningUpdates' ) This generates the following xcodebuild commands: Archive: xcodebuild -workspace ./Runner.xcworkspace -scheme Runner -destination 'generic/platform=macOS' -archivePath /path/to/archive -allowProvisioningUpdates archive Export with plist: xcrun -exportArchive -exportOptionsPlist '/path/to/plist' -archivePath /path/to/archive -exportPath '/output/path' -allowProvisioningUpdates Export options plist contents: &amp;lt;?xml version="1.0" encoding="UTF-8"?&amp;gt; &amp;lt;!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"&amp;gt; &amp;lt;plist version="1.0"&amp;gt; &amp;lt;dict&amp;gt; &amp;lt;key&amp;gt;installerSigningCertificate&amp;lt;/key&amp;gt; &amp;lt;string&amp;gt;Developer ID Installer: Company Inc (1234567891)&amp;lt;/string&amp;gt; &amp;lt;key&amp;gt;method&amp;lt;/key&amp;gt; &amp;lt;string&amp;gt;developer-id&amp;lt;/string&amp;gt; &amp;lt;key&amp;gt;signingStyle&amp;lt;/key&amp;gt; &amp;lt;string&amp;gt;automatic&amp;lt;/string&amp;gt; &amp;lt;/dict&amp;gt; &amp;lt;/plist&amp;gt; Notarization: ditto -c -k --rsrc --keepParent "My App.app" "My App.app.zip" xcrun notarytool submit "My App.app.zip" --output-format json --wait --key /path/to/key --key-id ABCDEFGHIJ --issuer 12345678-abcd-1234-5678-fc2d96b1735a Error Output Notarization fails with the following errors: { "severity": "error", "code": null, "path": "My App.app.zip/My App.app/Contents/Frameworks/some_package.framework/Versions/A/some_package", "message": "The binary is not signed with a valid Developer ID certificate.", "docUrl": "https://developer.apple.com/documentation/security/notarizing_macos_software_before_distribution/resolving_common_notarization_issues#3087721", "architecture": "arm64" } Key Details Using Xcode Cloud managed Developer ID certificates (not local certificates) ✅ Building, archiving, and notarizing through Xcode GUI works correctly Automatic signing is enabled Expected Behavior Frameworks should be automatically signed with the cloud managed Developer ID certificate during the export process, as they were in Xcode 15.4. Has there been a change in how framework signing is handled with cloud managed certificates in Xcode 16.2's command line tools? Any guidance on how to ensure frameworks are properly signed during automated builds when using automatic signing with cloud managed Developer ID certificates would be appreciated.

Under Xcode 26 beta 3, how to support new glass icons for iOS 26 and old icons for iOS 18?
I know there are several existing threads on this topic but things keep changing. The release notes for Xcode 26 beta 3 have the following statements for a couple of resolved issues: Asset Catalog Fixed: Unable to set Icon Composer icon as alternate iOS icon (153305178) (FB18025356) Icon Composer Fixed: Icon Composer icons back deploy to older versions of iOS, macOS, and watchOS with inconsistent rendering. (152258860) I had a working solution under beta 1 and beta 2 for both of these. But under beta 3, I am now seeing the new glass icons for my app when running on a simulated iOS 18 device. This is happening for both the main app icon and any alternates. This contradicts the statement that beta 3 fixes this issue. There is no documentation (that I can find) describing how you are supposed to support old icons for iOS 18 and new glass icons for iOS 26. There is no documentation for how to support alternate glass icons for iOS 26. What I'm doing at the moment (that worked before beta 3) was to have the normal iOS 18 app icons in the Asset catalog and to have the new glass icons added to the project. The filenames for the glass .icon files have the same name as the app icons in the Assets catalog. This worked under beta 1 and beta 2. And despite the Xcode 26 beta 3 release notes stating that Icon Composer icons no longer back deploy to iOS 18, I'm seeing the opposite. Beta 3 now does the opposite of that statement. Does anyone have a working solution that supports old iOS 18 app icons and new iOS 26 glass icons using Xcode 26 beta 3? Note, all of my testing is with simulated iOS devices and I'm running Xcode 26 beta 3 under macOS 15.5. Maybe that's an issue?

Using alternate app icons with Icon Composer
I've been messing around with converting my app icons to use Icon Composer. My app has multiple app icons, but I've noticed that I cant seem to set .icon files using the alternate app icon api. I believe this is due to the requirement that alternate app icons live in the Assets Catalogue but .icon files go anywhere in your project. Is there any plan to support this? Or am i missing something? I was able to successfully set a .icon file for the primary app icon.

Xcode 26 Beta Rebooting Problems
Hi, I've been running Xcode 26 beta ever since Beta 1 and haven't had rebooting problems. Now with Xcode beta (Version 26.0 beta 4 (17A5285i)) I'll be working on a project when the system (Mac mini 2025) suddenly reboots itself. This has been going on since beta 3. I am also running MacOS 26.0 Beta (25A5316i). I have filed a bug report. Is anyone else having this problem? Thanks, Dan Uff

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?

Unsupported SDK or Xcode version on iOS 26 builds
Since first beta of iOS 26 I've created a workflow where I can deploy to TestFlight the builds compiled using the iOS 26 SDK, and it has worked fine until yesterday when I started receiving this error: Unsupported SDK or Xcode version. Your app was built with an SDK or version of Xcode that isn’t supported. Although you can use beta versions of SDKs and Xcode to build and upload apps to App Store Connect, you need to use the latest Release Candidates (RC) for SDKs and Xcode to submit the app. For details on currently supported SDKs and versions of Xcode, visit: https://developer.apple.com/news/releases. I haven't changed anything in the workflow so I suspect it's a bug on Apple side? Or am I missing something? It is set to use "Latest Beta or Release" for both Xcode and macOS, archive and deploy to TestFlight Internal Testing. Thank you!

Xcode cloud time out issue
We are getting following error in xcode cloud "The step invocation hit a user timeout. The xcodebuild archive invocation timed out. No activity has been detected on stdout, stderr or the result bundle in 30 minutes" We are using following env to create a build. Xcode: 14.2 Macos: Ventura 13.2.1 We didn't face any issue in Ventura 13.2.0 and we are seeing this issue in our first build using ventura 13.2.1. The difference I see between successful and failure build, I don't see "Discovering Swift tasks after 'Compiling { list of swift file " in a failed build. I see compiling { list of swift file } and end of the compilation, the build is failing.

Compiling Swift Package with Dependency on Build Tool Plugin Fails in Xcode 26
Hi, in our Xcode project we have a Tooling package, which defines build tool plugins for generating compile time safe constants for our localization strings as well as assets using swiftgen. This is working very well in Xcode 16, but fails in Xcode 26 beta 1 and beta 2 as well. The failure is specifically: unsupported configuration: the aggregate target 'Localization' has package dependencies, but targets that build for different platforms depend on it. I've reduced this to a minimal sample project, which you can find here.. To reproduce: Open the Repro workspace, that is attached in Xcode. Try to build TestyPackage. You'll see the error. I've filed this bug during WWDC week, but no feedback yet and no solution in Xcode 26 beta 2. Here's the feedback number, in case you have this too and want to file a duplicate: FB17934050. Does anyone else have this issue and perhaps a solution?
