How to use the WebAssembly (wasm) binary module in macos App
During the release of our macOS App, we encountered the following issue: We need to support dynamic code loading of WebAssembly (wasm) inside our App, mainly by loading WebAssembly (wasm) binary modules. We discovered a problem: a wasm file is neither an executable nor a bundle, so it cannot be code-signed. Since our App needs to pass notarization, we have not set the com.apple.security.cs.allow-unsigned-executable-memory entitlement. Without setting com.apple.security.cs.allow-unsigned-executable-memory, loading a wasm module results in an “unsigned code” error that causes the process to crash. Could you please advise on what we should do to avoid this problem? Is it possible to apply for a special entitlement to allow com.apple.security.cs.allow-unsigned-executable-memory?

App ID Prefix Mismatch When Updating Old iOS App (2010) - "An App ID with Identifier is not available"
Hi all, I'm a solo iOS developer trying to update an app I released in 2010. My current Team ID is Q37598Q8GE, but the app's original App ID uses an old prefix, YHX995W43P. When I try to create a new App ID with the original Bundle ID (eu.andela.woordenes) to generate a new distribution provisioning profile, I get the error:An attribute in the provided entity has invalid value An App ID with Identifier 'eu.andela.woordenes' is not available. Please enter a different string. I understand this might be due to the old prefix from pre-2011, when Apple allowed multiple prefixes per account. I still have access to the app in App Store Connect and want to push an update, not create a new app. How can I resolve this?Can I reuse the existing App ID (eu.andela.woordenes with prefix YHX995W43P) for a new provisioning profile, or do I need to match my current Team ID (Q37598Q8GE)? If the Bundle ID is already taken by my current app, how do I update the app without changing the Bundle ID? Any steps to fix the prefix mismatch in Xcode or App Store Connect?

App Packaging: Error: HTTP status code: 403
Coming from Windows, I'm finding Mac app packaging farcically complicated, to the level of a Python sketch. I mastered Windows packaging, via Inno, in an hour or so, but it has taken me, on and off, the best part of a week to get to the point I am at with the Mac OS, and I'm nowhere near finished (rather, it hasn't finished with me). Every time I surmount one hurdle, another pops up, seemingly just for the jollies. I'm currently stuck at: 'Error: HTTP status code: 403. A required agreement is missing or has expired. This request requires an in-effect agreement that has not been signed or has expired. Ensure your team has signed the necessary legal agreements and that they are not expired.' My account lists no agreements in this category. I understand the need for security, but not the labyrinthine nature of the process. An inner-party member in the former Soviet Union overheard a drunken Stalin say, “I trust no one; not even myself". Apple trusts no one, but has true contempt for developers. Is there a simple way to work through the packaging process? Let me rephrase that: please God, let there be a simpler way of working through the process! Regards, in extremis, Richard

Unable to test my apps, crashing with provisioning profile validation
Since around September (iOS 26 release), i'm unable to test my app normally. It says "internet connection is required to verify [my certificate id]", or just crashing. All terms and conditions accepted, everything is valid, certificates are OK. Reinstallation via xcode does not help. Removal of provisioning profile, generating new does not help. Revoking of certificate and generating new does for around week, then it happens again, but do i need to do it every week now? In logs i see the following: default amfid validation failed because of missing trust and/or authorization (0xe8008026) error amfid not valid: 0xe8008026: The provisioning profile requires online authorization. error amfid Unexpected MISError (0xe8008026): The provisioning profile requires online authorization. default +0300 amfid /private/var/containers/Bundle/Application/5B8E560E-75B2-46EF-8606-02072D99E9CF//Frameworks/oss.dylib not valid: Error Domain=AppleMobileFileIntegrityError Code=-400 "An unknown error was encountered" UserInfo={NSURL=file:///private/var/containers/Bundle/Application/5B8E560E-75B2-46EF-8606-02072D99E9CF//Frameworks/oss.dylib, NSLocalizedDescription=An unknown error was encountered} default kernel AMFI: code signature validation failed. It looks like apple validation servers are not working, or is it iOS bug? All provisioning profiles are showing like "valid" in apple developer center. My network is not behind a proxy, connection is direct. If use EXACTLY the same app, signed with the same provisioning, same signature, on another test device, it works! When i reset current device to default settings and installing the EXACTLY same app after it, it works as well. Looking for a help from apple developer support

iOS App Exists after launch
Hello, my iOS apps are exiting right after launch on a few of our iOS devices. I tried a couple of my apps that are deployed to our fleet and they do the same thing. If I run the app(s) in the Simulator it works fine and if I run the app(s) on the offending devices it works fine as well. Once I stop the run in Xcode the app on the device will not launch. I'm thinking something is missing like a certificate etc. Just not sure. Any ideas on how to troubleshoot this? I would really like to get this fixed.

Automatic Signing failed and Provisioning profile is missing the activitykit
I am a professor at the Mercer University School of Medicine (Macon, GA) and I teach a stress reduction course for first year medical students. I am developing an app to allow the students to trace their mediations as well as time them. Using ChatGPT with Xcode, I was able to get all the features in the app working except that the stopwatch timer would not continue when the iPhone goes to sleep. When ChatGPT made some changes, the build failed because automated signing failed and the com.apple developer.activity kit entitlement is missing I don’t see Live Activities in the capability section of signing & Capabilities and I don’t know how to fix the provisioning profile. How can I get help for this? Thank you!

code signature validation failed fatally - Unsatisfied Entitlements
Hello, We have a working application with several entitlements - com.apple.developer.endpoint-security.client and com.apple.developer.team-identifier. Recently, the Developer ID signing certificate expired and we created a new one according to the instructions on the website. Also the provisioning profile for those entitlements expired so we edited it to use the new certificate. We built using xcodebuild in a script and signed with codesign, We supply the certificate id and the entitlement in a plist file like this : codesign --timestamp --force --sign "${application_signature}" --options=runtime "${obj}" --entitlements "${SR_ENTITLEMENT_PATH}" (those env vars hold the correct values for the cert id and plist path as far as we checked). The signing works and looks ok with "codesign -dvvv": (XXXX replaces the real file name for privacy) Signature size=9050 Authority=Developer ID Application: XXXXXX. (XXXXX) Authority=Developer ID Certification Authority Authority=Apple Root CA Timestamp=16 Oct 2025 at 11:09:53 AM Info.plist=not bound TeamIdentifier=XXXXX Runtime Version=14.5.0 Sealed Resources=none Internal requirements count=1 size=184 [Dict] [Key] com.apple.application-identifier [Value] [String] XXXXX.com.XXXX.XXXX [Key] com.apple.developer.endpoint-security.client [Value] [Bool] true [Key] com.apple.developer.team-identifier [Value] [String] XXXXXX` But when the app need to run it is killed and the console shows the following: amfid: /private/tmp/XXXXX not valid: Error Domain=AppleMobileFileIntegrityError Code=-420 "The signature on the file is invalid" UserInfo={NSURL=file:///private/tmp/XXXXX, NSLocalizedDescription=The signature on the file is invalid} kernel: mac_vnode_check_signature: /private/tmp/CybereasonSensor: code signature validation failed fatally: When validating /private/tmp/XXXXX: Code has restricted entitlements, but the validation of its code signature failed. We didn't change any code or build differently (it's done by a CI jenkins job. So if the file is signed and the and has the entitlements why does it fail? what should be done? Thanks, Boaz

Notarization Incomplete for Github Workflows
Hello, I am new to the apple developer program. I, and my team, are working on porting some medical software that we have written from Windows to MacOS. We obviously want to notarize our app to make it easy for professionals and colleagues to use. The software is entirely written in python and includes ffmpeg for one of the features to export the medical data to video and compiled to a single file with pyinstaller, like so: pyinstaller app_name.py --noconfirm --onefile --add-data "ffmpeg:ffmpeg" chmod +x dist/app_name* We are currently adding the signing and notarization of the app to our github workflow. The workflow build a successful app with the correct structure and is able to be run if we allow it past the MacOS firewall. We are signing the app like so: run: | BINARY_PATH="dist/app_name" IDENTITY=$(security find-identity -p codesigning -v | grep -E 'Developer ID Application|Mac Developer' | head -n1 | awk -F\" '{print $2}') echo "Using identity: $IDENTITY" security unlock-keychain -p "" build.keychain codesign --verbose=4 --force --options runtime --timestamp --entitlements .github/mac_build_tools/entitlements.plist --sign "$IDENTITY" "$BINARY_PATH" codesign --verify --verbose=4 "$BINARY_PATH" We then also move the binary around into an app structure and sign that as well like so echo "Moving contents to SedPlot.app" mkdir -p dist/app_name.app/Contents/MacOS mv "$BINARY_PATH" dist/app_name.app/Contents/MacOS cp .github/mac_build_tools/Info.plist dist/app_name.app/Contents echo -n "APPL????" > dist/app_name.app/Contents/PkgInfo echo "Signing App" codesign --verbose=4 --force --options runtime --timestamp --entitlements .github/mac_build_tools/entitlements.plist --sign "$IDENTITY" dist/app_name.app codesign --verify --verbose=4 dist/app_name.app codesign --display --entitlements :- dist/app_name.app If I upload the artifact and check its properties, everything looks good. It has the correct ID associated with it and shows as valid when I use codesign --verify on it. I start having issues when I move onto notarization, like so: cd dist echo "Zipping and checking the zip" ditto -c -k --keepParent app_name.app app_name.zip zipinfo -1 app_name.zip | head echo "$AC_API_KEY" > AuthKey.p8 SUBMISSION_ID=$(xcrun notarytool submit app_name.zip \ --key AuthKey.p8 \ --key-id "$AC_KEY_ID" \ --issuer "$AC_ISSUER_ID" \ --team-id "TEAM_ID" \ --output-format json | jq -r '.id') echo "Submitted notarization with ID: $SUBMISSION_ID" All of the print statements for errors look good at this point, and the submission ID shows up in my history when I query it. However, all 7 attempts that I have made to notarize this app hang for indefinite amounts of time. We are hoping to submit our tool for publication soon, and it would be helpful to know if there is an issue causing the hang on our end or if this is an issue with new developers. I have been reading around the forums and see some notes about this taking about a week until the system start to "learn" about our development team and our attempts to notarize. I also know that there is limited amounts that can be said about the backend of the notarizations step. What would be helpful is a few things: I would like feedback about if there is a fundamental flaw in our approach for signing and notarizing our application, so that we can identify it. I would appreciate some guidelines about how long to expect this notarization step to take until we can get notarization to finish within 10s of minutes, as we have a hard-coded 30 min wait time for the completion of the notarization in our workflow right now. It would be helpful to know how to check our logs, as requesting the logs for any of our attempts results in being told that the logs are not available yet. In case someone from apple is interested in this and wants to check, the most-recent submission ID (the one that I believe should be most-likely correct and valid) is 9ef24966-42a5-47db-a7e0-c6baf0310ac4 Thank you in advance!

Building SimpleAudioDriver example
Hi there, I am trying to build the Apple SimpleAudioDriver example but fail with codesign and/or provisioning. I would be ok for now with the local option, but XCode 16.4 doesn't show the option "build to run locally" (SIP is disabled). When using "Automatically manage signing" it ends in a "Please file a bug report". I found that having two different development teams tripped it up, so I deleted all certificates and keys and made sure to be only signed into one account in Xcode. Can anyone give advice? Thanks a ton! Here is the URL to the sample: https://developer.apple.com/documentation/coreaudio/building-an-audio-server-plug-in-and-driver-extension macOS: 15.6.1 XCode: 16.4 Hardware: MacBook Pro M2 Max SIP: disabled

Unable to provision target
I have added an in-app purchase function into my app, and have enabled in-app purchase profile in developer portal(it's on by default and is marked gray in developer portal, I don't know if that's how it supposed to look like). I have issued the agreements and tried signing the app both manually and automatically, but neither of that worked. App can be built successfully in simulator but does not show the simulation window, but cannot build on real device or archive. Errors: Missing com.apple.developer.in-app-purchase, com.apple.developer.in-app-purchase.non-consumable, and com.apple.developer.in-app-purchase.subscription entitlements. Automatic signing failed Xcode failed to provision this target.

Provisioning Profile Defect: App Attest Entitlement (com.apple.developer.app-attest.environment) Missing Despite Enabled Capability
Hello everyone, I'm facing a critical, blocking issue where my developer account (Team ID: K655PX7A46) is unable to generate a valid provisioning profile with the App Attest entitlement. I have confirmed this is a server-side issue and am hoping to get visibility from an Apple engineer who can investigate. The Problem: When I generate a provisioning profile for an App ID with the "App Attest" capability enabled, the resulting profile is defective. It is missing the required com.apple.developer.app-attest.environment key in its entitlements dictionary, causing Xcode to fail the build. What I Have Proven: The issue is not a misconfiguration. The App Attest capability is correctly enabled and saved on the App ID configuration page. The issue is not isolated to one App ID. I created a brand new App ID from scratch, enabled the capability during creation, and the server still generates a defective profile with the same missing entitlement. I have definitive proof by inspecting the downloaded .mobileprovision file. The contents confirm the required key is missing. Steps to Reproduce on My Account: Create a new App ID on the Developer Portal. Enable the "App Attest" capability and save. Generate a new "iOS App Development" provisioning profile for this App ID. Download the profile and inspect its contents via security cms -D -i [profile]. Observe that the com.apple.developer.app-attest.environment key is missing. The Evidence (Contents of the Defective Profile): Here is the output from inspecting the profile for a brand new App ID (com.technology519.linksi.app2). As you can see, the correct entitlement is missing, and an incorrect devicecheck entitlement is present instead. This is a critical bug in the provisioning profile generation service for my account that is blocking all development. I have already filed a support ticket (Case #102721408444) but have so far only received generic, unhelpful responses. Can an Apple engineer please investigate this server-side issue with my account? Thank you.

Notary Tool credentials failing to stay persistently in the keychain
The problem is the following: We create a keychain item called NotaryTool (There are multiple accounts that use Notary tool and we created it for all of them ) This is created in the following way: $ xcrun notarytool store-credentials This process stores your credentials securely in the Keychain. You reference these credentials later using a profile name. Profile name: NotaryTool We recommend using App Store Connect API keys for authentication. If you'd like to authenticate with an Apple ID and app-specific password instead, leave this unspecified. Path to App Store Connect API private key: //AuthKey_ABCDEFGH.p8 App Store Connect API Key ID: <ABCDEFGH> App Store Connect API Issuer ID: ABCDEF-ABCD-1234-1234-1234567 Validating your credentials... Success. Credentials validated. Credentials saved to Keychain. To use them, specify `--keychain-profile "NotaryTool"` The key is downloaded from Apple and some other IDs are provided alongside. These should remain in the keychain for as long as the user process is running (just like any other process) A few runs are successful when we run with the profile that was created. After a few runs we start seeing a failure. Now we are seeing the following issue where the keychain item just vanishes: Error: No Keychain password item found for profile: NotaryTool\n\nRun 'notarytool store-credentials' to create another credential profile.\nError during the not process\nTue Aug 26 06:02:09 2025 Notarization failed with notarytool with exit code 17664: \nTue Aug 26 06:02:09 2025 could not upload for notarization!!!
