Upload failed Validation Issue WKApplication or WKWatchKitApp is required
I added a watchkit extension to an existing app. I get this error when uploading to App Store Connect. Building the archive itself is fine: Prepared archive for uploading Upload failed error: Validation failed Missing Info.plist value. A value for the key “WKApplication”, or “WKWatchKitApp” if your project has a WatchKit App Extension target, is required in “Runner.app/Watch/watch_Watch_App.app” bundle. For details, see: https://developer.apple.com/documentation/watchkit/creating_independent_watchos_apps/setting_up_a_watchos_project have the exact same issue when bundling. I added the flag manually in a additional plist fields entry with WKApplication=1 because my Info.Plist is generated and it didn't help. I wrote a custom Run Script Phase that added the flag and that didn't help as well. I need a reply from someone from Apple here. This needs to be fixed.

The specified iOS provisioning profile '' could not be found.
I have developed multiple applications in the past using windows Visual studio 2022 and have never had any issues during development. However this time I am receiving the same error The specified iOS provisioning profile '{profile}' could not be found. Please enable Automatic Provisioning from the iOS Bundle Signing page. Everytime I try to deploy even though I can see that all the appropriate entries are in my apple developer portal, and I can see the profiles have been automatically downloaded to my computer. (The App identifier also matches the one establisehd in the apple developer portal and is linked to the profile). The only thing I can think of, is that my renewal of my developer account got rejected by my bank at first, but on another attempt (about 2 weeks ago) it all went through fine.

Investigating Third-Party IDE Code-Signing Problems
I regularly see questions from folks who’ve run into code-signing problems with their third-party IDE. There’s a limit to how much I can help you with such problems. This post explains a simple test you can run to determine what side of that limit you’re on. If you have any questions or comments, please put them in a new thread here on DevForums. Put it in Code Signing > General topic area and apply whatever tags make sense for your specific situation. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Investigating Third-Party IDE Code-Signing Problems DTS doesn’t support third-party tools. If you’re using third-party tooling and encounter a code-signing problem, run this test to determine whether you should seek help from Apple or from your tool’s vendor. IMPORTANT Some third-party tools create Xcode projects that you then build and run in Xcode. While that approach is understandable, it’s not something that DTS supports. So, the steps below make sense even if you’re already using Xcode. To check that code-signing is working in general: Launch Xcode. In Xcode > Settings > Accounts, make sure you’re signed in with your developer account. Create a new project from the app project template for your target platform. For example, if you’re targeting iOS, use the iOS > App project template. When creating the project: Select the appropriate team in the Team popup. Choose a bundle ID that’s not the same as your main app’s bundle ID. Choose whatever language and interface you want. Your language and interface choices are irrelevant to code signing. Choose None for your testing system and storage model. This simplifies your project setup. In the Signing & Capabilities editor, make sure that: "Automatically manage signing” is checked. The Team popup and Bundle Identifier fields match the value you chose in the previous step. Select a simulator as the run destination. Choose Product > Build. This should always work because the simulator doesn’t use code signing [1]. However, doing this step is important because it confirms that your project is working general. Select your target device as the run destination. Choose Product > Build. Then Product > Run. If you continue to have problems, that’s something that Apple folks can help you with. If this works, there’s a second diagnostic test: Repeat steps 1 through 10 above, except this time, in step 4, choose a bundle ID that is the same as your main app’s bundle ID. If this works then your issue is not on the Apple side of the fence, and you should escalate it via the support channel for the third-party tools you’re using. On the other hand, if this fails, that’s something we can help you with. I recommend that you first try to fix the issue yourself. For links to relevant resources, see Code Signing Resources. You should also search the forums, because we’ve helped a lot of folks with a lot of code-signing issues over the years. If you’re unable to resolve the issue yourself, feel free to start a thread here in the forums. Put it in Code Signing > General topic area and apply whatever tags make sense for your specific situation.

Problem adding Call Directory capability
I added a extension called Call Directory to an IOS app as we want to call blocking and caller id. I was able to add App Groups to both runner and CallDirectory. I cannot see of add Call Directory capability. Am I missing something. I added the extension through the Call Directory Target template. If I try to add this to CallDirectory.enitlements manually com.apple.developer.callkit.call-directory call-blocking caller-identification i recieve this signing error. Provisioning profile "iOS Team Provisioning Profile: "" doesn't include the com.apple.developer.callkit.call-directory entitlement. I cannot add Call Directory to an identifier in Apple Developer either.

Dynamic Library cannot call exposed C function
This is a lengthy one. I have basically compiled a Rust binary into a dylib and packaged into a .xcframework that contains per arch .frameworks. This loads correctly when run from Xcode into a real iOS device. However, when deployed to TestFlight the app crashes. Here is what is a bit different, the dylib is not fully self-contained. It tries to reach in an use C functions I have exposed in my library code. Calling functions that are just within the dylib and just return works fine, but the moment it tries to call one of the exposed functions it crashes. A full in-depth step by step of how I packaged the binaries can be found in my website: https://ospfranco.com/complete-guide-to-dylibs-in-ios-and-android When I look at the TestFlight crash report there are no symbols but the termination cause via WatchDog is: Termination Reason: CODESIGNING 2 Invalid Page I have declared my functions as such: OBJC_EXTERN void ios_prepare_request(const char *url) #define EXPORT __attribute__((visibility("default"), used, retain)) extern "C" { EXPORT void ios_prepare_request(const char *url) { NSString *urlString = [NSString stringWithUTF8String:url]; request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]]; } } // Function used to prevent optimization void force_symbol_registration() { // Force these symbols to be included in the binary by referencing them volatile void *ptrs[] = {(void *)ios_prepare_request,}; // Prevent compiler from optimizing away the array (void)ptrs; } And I load my framework as: opacity::force_symbol_registration(); // NSBundle *dylib_bundle = // [NSBundle bundleWithIdentifier:@"com.opacitylabs.sdk"]; // NSString *dylib_path = [dylib_bundle pathForResource:@"sdk" ofType:@""]; // // Load the dynamic library // void *handle = dlopen([dylib_path UTF8String], RTLD_NOW | RTLD_GLOBAL); // if (!handle) { // NSString *errorMessage = [NSString stringWithUTF8String:dlerror()]; // *error = // [NSError errorWithDomain:@"OpacitySDKDylibError" // code:1002 // userInfo:@{NSLocalizedDescriptionKey : // errorMessage}]; // return -1; // or appropriate error code // } // Make sure the main executable's symbols are available dlopen(NULL, RTLD_NOW | RTLD_GLOBAL); NSBundle *frameworkBundle = [NSBundle bundleWithIdentifier:@"com.opacitylabs.sdk"]; if (![frameworkBundle isLoaded]) { BOOL success = [frameworkBundle load]; if (!success) { NSString *errorMessage = @"Failed to load framework"; *error = [NSError errorWithDomain:@"OpacitySDKDylibError" code:1002 userInfo:@{NSLocalizedDescriptionKey : errorMessage}]; return -1; } } As you can see, I have also tried dlopen both work when run from Xcode but crash when deployed on testflight. I have tried re-signing the xcframework/frameworks on a pre build step but it doesn't work As stated, I can call the functions inside the dylib, but once they try to call my exposed code it crashes Is this achievable at all or just a limitation of the iOS sandbox?

Provisioning Profile, Automatic Sign In Failures
Hello, I'm working in Xcode Version 16.4. I have not been able to sign in without errors. I've paid for the dev account. I've created certificates. Downloaded and uploaded CSRs. Use background mode, not used background mode. Nothing seems to work. Thank you for looking into this! Hopefully you can point me in the right direction or find a solution. Attached screenshots with errors.

Notarytool in progress for over 2 days
Whilst waiting for the company developer account I successfully notarised an app/pkg On switching to the company account the app/pkg has been stuck in progress for over 2 days (see below) The initial submission was via Xcode and later via command line. The last one was when I updated bundle ids etc and built with Github Actions. The initial submission did coincide with a service outage, however that is marked as resolved. I would like to cancel all of them now that I have switched the signing account and the bundle ID but there seems no way to do this? Thoughts and comments welcome. Thanks Paul -------------------------------------------------- createdDate: 2025-08-14T11:03:24.837Z id: edf215d0-4d15-4075-aa6f-4755a35b3d45 name: ZenityEndpointAgent.pkg status: In Progress -------------------------------------------------- createdDate: 2025-08-12T21:36:36.345Z id: 9c98de09-d3aa-449b-ad47-7e721b0342c5 name: AIEdgeDeviceAgent.pkg status: In Progress -------------------------------------------------- createdDate: 2025-08-12T16:58:50.891Z id: 9206f9be-0fc4-4c6c-aa66-8fcbe3332155 name: AIEdgeDeviceAgent.pkg status: In Progress -------------------------------------------------- createdDate: 2025-08-12T10:37:35.624Z id: b20d1dd0-084e-441c-87a6-641fb088819e name: AIEdge Device Agent.zip status: In Progress

Invalid Code Signing Entitlements
Hi, I have a .NET MAUI app which I've added subscriptions to using the Plugin.InAppBilling nuget package. When I tested on TestFlight I got an almost immediate crash. After doing some research I followed advice to add an Entitlements.plist file to Platforms > iOS with the following entry: com.apple.developer.in-app-purchase The distribution provisioning profile I'm using to sign my app has the App ID set to an Identifier which has "In-App Purchase" ticked, but greyed out in it's "Capabilities" section on https://developer.apple.com/. I'm not sure why it's ticked and greyed out, but I assume that means that "In-App Purchase" is enabled. The app runs file locally but when I create an IPA file and add it to Transporter for upload to App Store Connect I get the following error: "Validation failed (409) Invalid Code Signing Entitlements. Your application bundle's signature contains code signing entitlements that are not supported on iOS. Specifically, key 'com.apple.developer.in-app-purchase' in 'Payload/[Removed].app/[Removed]' is not supported. (ID: [Removed])". Here is the structure of my csproj code for creating a IPA file for iOS: The command I use: dotnet publish [Removed]/app.csproj -f:net9.0-ios -c:Release ^ /p:PlatformTarget=Arm64 ^ /p:RuntimeIdentifier=ios-arm64 ^ /p:ServerAddress=[Removed] ^ /p:ServerUser=[Removed] ^ /p:ServerPassword=[Removed] ^ /p:ArchiveOnBuild=true ^ /p:BuildIpa=true I'm stuck trying to figure this out. If you could please point out any issues with what I'm doing or if you have any suggestions to resolve the problem I would very much appreciate it. Thanks, Ben

Unsigned macOS app installed in /Applications does not appear in Launchpad
Hello, I have a macOS app built with Flutter’s macOS target (native Xcode project). The app is unsigned (no Developer ID code signing / notarization). The .app bundle looks valid: CFBundlePackageType = APPL Unique CFBundleIdentifier No LSUIElement or LSBackgroundOnly Executable exists and is runnable Placed at /Applications/MyApp.app (top-level), runs fine from Finder However, it does not show up in Launchpad. What I tried: Remove quarantine: xattr -dr com.apple.quarantine "/Applications/MyApp.app" Force Launch Services registration: /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -f "/Applications/MyApp.app" Rebuild LS caches: /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user Reset Launchpad DB and restart Dock: defaults write com.apple.dock ResetLaunchPad -bool true && killall Dock Verified bundle structure/type: mdls -name kMDItemContentType -name kMDItemKind "/Applications/MyApp.app" → shows com.apple.application-bundle / Application Questions Is code signing/notarization required for an app to appear in Launchpad (even if it runs from Finder)? What additional conditions cause Launchpad to skip an otherwise valid, unsigned .app in /Applications? Are there deeper Launch Services or Dock database checks I can run to diagnose why this specific app is excluded?

login item still displays my personal name after migrating to company account
I have a mac app which has a launch agent. I signed it with my account, but it always shows as my personal 'XX XXX" in the login items of mac settings. Actually this is the reason I switched my personal account to a company account. But now it is still shown as 'XX XXX' in the login items after I signed up again with this company account. Do you know how I can change this? The identity I also tried to create a new one with the team, but it does not allow me to create a new one. Chatgpt recommends revoking the current one, but this will affect our old release.

Cannot launch an app sucessfully stapled and validated
Hey, when I try to launch my app it prompts me with a "Apple could not verify" popup. The thing is the app has been signed and stapled. xcrun stapler validate .app for my app returns "The validate action worked!" If I also run syspolicy_check distribution .app it returns: "App passed all pre-distribution checks and is ready for distribution" Any idea?

Screen Time API, DeviceActivity, Family Controls, Entitlements, Provisioning Profile
Hello everyone, I'm hoping to find a solution for a critical issue that is blocking my app's submission to the App Store. My app uses the Screen Time API and therefore has a main app and a DeviceActivityMonitor extension. The main app has been successfully granted the Family Controls (Distribution) entitlement. However, the DeviceActivityMonitor extension is stuck with only the Family Controls (Development) entitlement. This mismatch causes my build to fail during the archive/distribution process with the error: "Provisioning profile failed qualification. Profile doesn't support Family Controls (Development)." This is a hard blocker, as the extension is a mandatory part of the API. I have already filled out the entitlement request form and also contacted Developer Support (Case #102666581576), who confirmed they could not assist and directed me here. My question is: What is the correct procedure to escalate or resolve the issue of a required extension not receiving the distribution-level Family Controls entitlement after the main app has already been approved? Has anyone else encountered this specific "Development" vs. "Distribution" mismatch and found a definitive way to resolve it? Any guidance would be greatly appreciated. Thank you!

GateKeeper rejects application bundles with a file name with an NFC/NFD problem by copying with Finder
I made a macOS application using Swift Package and distributed it in dmg format through Apple Notary service. However, we received a report from a user that it can be launched from a disk image mounted from dmg, but when copied to /Applications, the app is broken and does not start. I looked into why this happened, I noticed that the codesign command returned different results when copying the application bundle and /Applications on the volume mounted dmg with Finder. Mounted dmg: OK ❯ codesign --verify --deep --verbose /Volumes/azoo-key-skkserv/azoo-key-skkserv.app /Volumes/azoo-key-skkserv/azoo-key-skkserv.app: valid on disk /Volumes/azoo-key-skkserv/azoo-key-skkserv.app: satisfies its Designated Requirement Copied by Finder: Bad codesign reports that there are 148 added/missing files. ❯ codesign --verify --deep --verbose /Applications/azoo-key-skkserv.app /Applications/azoo-key-skkserv.app: a sealed resource is missing or invalid file added: /Applications/azoo-key-skkserv.app/Contents/Resources/AzooKeyKanakanjiConverter_KanaKanjiConverterModuleWithDefaultDictionary.bundle/Contents/Resources/Dictionary/louds/グ1.loudstxt3 (skip...) file missing: /Applications/azoo-key-skkserv.app/Contents/Resources/AzooKeyKanakanjiConverter_KanaKanjiConverterModuleWithDefaultDictionary.bundle/Contents/Resources/Dictionary/louds/グ1.loudstxt3 (skip...) Copied by ditto: OK ❯ ditto /Volumes/azoo-key-skkserv/azoo-key-skkserv.app /Applications/azoo-key-skkserv.app ❯ codesign --verify --deep --verbose /Applications/azoo-key-skkserv.app /Applications/azoo-key-skkserv.app: valid on disk /Applications/azoo-key-skkserv.app: satisfies its Designated Requirement I made a simple macOS application to explain this problem in an easy-to-understand way. You can download dmg in github releases, mount dmg, copy it in the Finder, and check if there is a problem by running the codesign command. https://github.com/mtgto/example-utf8-mac-notarization As a result, I learned the following two things. Occurs only with resources with file names whose values change due to NFC/NFD normalization No problems occur with the resources of the application itself. Generated by the Swift Package resources that the application depends on I think this is a problem with Finder or Gatekeeper.

Family Controls (Distribution) entitlement missing for Device Activity Monitor extension - blocking TestFlight distribution
Hi Apple Developer Community, I'm experiencing an issue with Family Controls entitlements for my iOS app that I'd like to discuss and see if others have encountered similar problems. Background: My app (BrightStart) uses Family Controls to help users build healthy morning routines by temporarily blocking distracting apps until they complete a sunlight exposure session. The core functionality relies on automatic time-based blocking (e.g., block social media apps from 6-8am daily). The Problem: I have Family Controls working perfectly in development builds, but I'm blocked from distributing via TestFlight due to entitlement issues with my Device Activity Monitor extension. Technical Details: Main app bundle ID: app.brightstart.app ✅ Has both "Family Controls (Development)" and "Family Controls (Distribution)" options available Extension bundle ID: app.brightstart.app.BrightStartMonitorExtension ❌ Only shows "Family Controls (Development)" - no Distribution option Error when archiving for TestFlight: ❌ Provisioning profile failed qualification Profile doesn't support Family Controls (Development). Family Controls (Development) feature is for development only. Please use Family Controls (Distribution) for distribution. Impact: Cannot upload to TestFlight for beta testing Native FamilyActivityPicker falls back to mock UI in distributed builds Automatic scheduled app blocking (via DeviceActivityMonitor) doesn't function in production Questions for the community: Has anyone successfully gotten "Family Controls (Distribution)" enabled for a Device Activity Monitor extension? Is this a known limitation, or should I expect this option to be available? Are there alternative approaches for time-based automatic app blocking that work in distribution builds? Should I contact Apple Support directly about enabling this entitlement for the extension? Btw, Cursor wrote this summary above, so it could be just hallucinating the issue? Would really appreciate anyone's thoughts here.

Xcode Signing and Capabilities
I'm currently befuddled by the entire signing and certificate process. I don't understand what I need, what the team admin needs to do, or how to go about doing it so that I can build the project. We've managed to have this working in the past but I guess the system has changed somewhat. Here's what we have going: A Unity project which hasn't changed from a few years ago. I build the project in unity, open the Xcode project and this: There's an issue with the Signing and Capabilities. If I choose automatic setup it shows an error saying that it requires a development team. I had the account admin add my Apple ID to the team so I'm not sure why that's an issue still. Do I need to pay the 99$ to be able to building Xcode? If I try to do it manually I select the provisioning profile that the account admin sent me and it auto selects the team associated with the provisioning profile I guess but then there's no singing certificate. The error says: There is no signing certificate "iOS Development" found. No "iOS Development" signing certificate matching team ID "V7D5YBZRMV" with a private key was found. So, if someone could explain to me like I'm 5 the entire signing and certificate process is and let me know what we're doing wrong with the team/provisioning profile/certificate setup I would be very much appreciative.

unzip identifier is not unique?
In Swift I'm using unzip by launching a Process to unzip a file. I added a launchRequirement to the process in order to make sure the executable is code signed by Apple and the identifier is com.apple.unzip. After testing out my code on another machines (both physical and virtual), I found out that in some the identifier is actually com.apple.zipinfo, which broke the SigningIdentifier requirement. It's safe to assume that /usr/bin/unzip can be trusted since it's in a System Integrity Protection (SIP) location, but I'm wondering why this executable has different identifiers?

VoIP Entitlement
Good afternoon, Our team is currently developing a mobile application that includes video call functionality, and we are seeking the optimal approach to enable incoming calls on iOS devices. Ideally, we would like calls to be delivered even when the app is completely closed or after the device is restarted. As I understand it, this may require obtaining VoIP permissions; otherwise, calls may only work when the app is open or running in the background. I would appreciate it if you could confirm my understanding and advise me on the steps or requirements for obtaining the appropriate permissions. Currently, when I try to launch the app in XCode, I see an error (screenshot).

com.apple.developer.family-controls Distribution Timeline?
Hi All, Like many others I'm a little confused with gaining access to the family controls capability. Our app is ready to push to testflight, and we sent the request to apple last week. However only learning today that we need to request for the shield extension as well. I wanted to ask what the expected timeline is for being approved? I've seen posts here saying less than a week, and some people having to wait longer than 6 weeks. Any advise or guidance on getting approved smoothly & swiftly would be highly appreciated
