Failed Registering Bundle Identifier of watch app
Hi, after 2 years of not updating my app on appstore i wanted to submit an update for my iOS app which also containts a watch app target. When i try to submit it to upload it i get the following errors: Failed registering bundle identifier The app identifier "(myappBundleID).watchkitapp" cannot be registered to your development team because it is nit available. Change your bundle identifier to a unique string to try again. No Profiles for "(myappBundleID).watchkitapp" were found. Xcode culdn't find any iOS App Store provisining profiles matching "(myappBundleID).watchkitapp" Since i have my app already in store with that bundle identifier i don't know why it can not be registered to my team. Also i don't want to change the bundle identifier because then i can not publish it as update to store.

First app for me - stuck on Notarization
Hey there! Thanks so much for all the great posts about this topic! I'm fairly new to Mac development since a few months back, and I've been really impressed with Apple's developer tools and ecosystem so far. It's been an exciting journey building for macOS! However, I've hit a bit of a roadblock with the notarization process via direct download and would really appreciate some guidance from you more experienced developers. I understand that Apple has built a well-designed automated system to maintain high security for users, but I'm wondering: What's the normal timeframe for notarization to complete? What are usually the most common reasons if it takes longer than expected? Is there anyone at Apple who can help if the process gets stuck? I'm really excited to launch my app and continue developing for this amazing platform, so any tips from experienced Apple developers would be hugely appreciated! Thanks in advance! 🙏

notarytool is giving me HTTP status error
I am using the xcrun notarytool submit --apple-id xxxxx@gmail.com --password xxxxx--team-id xxxxxx --output-format json --wait --no-progress /my/dmg/file to notarize my DMG file. But it always gives me back the error, 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. I did log in my developer account and found no place to sign any agreement. Actually in the morning when I logged in the developer account, it indeed pop up the agreement for me to sign and I did sign it. But now it seems I don't have any more agreements to sign. So, any ideas about what I should do?

Notarization Rejection - The binary is not signed with a valid Developer ID certificate
Notarization Rejects Valid Developer ID Certificates - Apple Infrastructure Issue? Environment macOS: 15.6.1 Xcode: 26.0.1 Architecture: arm64 (Apple Silicon) Team ID: W---------- Certificate Status: Valid until 2030 (verified on developer.apple.com) Problem Apple's notarization service consistently rejected properly signed packages with error: "The binary is not signed with a valid Developer ID certificate." Despite: ✅ Valid certificates on developer.apple.com ✅ Local signing succeeds (codesign --verify passes) ✅ Proper certificate/key pairing verified ✅ Package structure correct Failed Submission IDs September 2025: adeeed3d-4732-49c6-a33c-724da43f9a4a 5a910f51-dc6d-4a5e-a1c7-b07f32376079 3930147e-daf6-4849-8b0a-26774fd92c3c b7fc8e4e-e03c-44e1-a68e-98b0db38aa39 d7dee4a1-68e8-44b5-85e9-05654425e044 da6fa563-ba21-4f9e-b677-80769bd23340 What I've Tried Re-downloaded fresh certificates from Apple Developer Portal Verified certificate chain locally Tested with multiple different builds Confirmed Team ID matches across all configurations Verified no unsigned nested components Waited 3 months for potential propagation delays Verified all agreements are current and accepted Re-tested with minimal test package - same error persists Local Verification # Certificates present and valid security find-identity -v -p codesigning | grep "Developer ID" 1) XXXXXXXXXX "Developer ID Application: <<REDACTED>> (W----------)" 2) XXXXXXXXXX "Developer ID Installer: <<REDACTED>> (W----------)" # Signing succeeds codesign --verify --deep --strict --verbose=2 [app] → Success Question This appears similar to thread #784184. After 3 months and ensuring all agreements are signed, the issue persists with identical error. The certificates work for local signing but Apple's notarization service rejects them. Could this be: Backend infrastructure issue with Team ID W----------? Certificate not properly registered in Apple's notarization database? Known issue requiring Apple Support intervention? Has anyone else experienced valid Developer ID certificates being rejected specifically by the notarization service while working locally?

Can't Provision A Device
Hi First, I hope I'm in the right place, I'm not certain. I'm having my first attempt at IOS development and want to see the progress I've made on my phone. I plugged it in to my Mac and selected it as a preview device and got the following messages in the Signing & Capabilities screen: Your team has no devices from which to generate a provisioning profile. Connect a device to use or manually add device IDs in Certificates, Identifiers & Profiles. https://developer.apple.com/account/ No profiles for '...' were found: Xcode couldn't find any iOS App Development provisioning profiles matching '...'. My account and personal team are shown in the Xcode settings, but it says 0 Provisioned Devices. I also tried restarting, and enabled developer mode on the phone. I checked the provided link, but saw nowhere to add a device ID. Clearly I don't understand what I'm doing. Can anyone help me make sense of this?

Flutter iOS Widget Extension – CodeSign Failed (ActivityKit entitlement missing, cannot enable in Identifiers)
Hello everyone, I am developing a Flutter iOS application that includes a Widget Extension + Live Activity (ActivityKit). The project runs successfully on the iOS simulator when launched directly from Xcode, but it cannot be signed properly via Flutter and I cannot upload the build to App Store Connect due to the following CodeSign error: Command CodeSign failed with a nonzero exit code Provisioning profile "…" doesn't include the entitlement: com.apple.developer.activitykit.allow-third-party-activity This error never goes away no matter what I try. And the main problem is that my App ID does NOT show any ActivityKit or Live Activity capability in the Apple Developer portal → Identifiers → App ID. So I cannot enable it manually. However: Xcode requires this entitlement Flutter requires this entitlement When I add the entitlement manually in the .entitlements file, Xcode says: “This entitlement must be enabled in your Developer account. It cannot be added manually.” So I am stuck in a loop where: Apple Developer portal does not show ActivityKit capability Xcode demands the ActivityKit entitlement Signing fails App Store upload fails And Live Activity is a critical feature of my app What I have already done ✔ “Automatically manage signing” is enabled ✔ Correct Team is selected for both Runner and the Widget Extension ✔ Bundle IDs are correct: com.yksbuddy.app com.yksbuddy.app.TimerWidgetExtension ✔ Deleted Derived Data completely ✔ Tried removing all ActivityKit-related entitlement keys manually ✔ Deleted Pods, reinstalled, rebuilt ✔ App Group settings match between Runner and Extension ✔ The same Live Activity code works perfectly in a clean Xcode-only project ✔ But fails only inside a Flutter project structure ✔ Xcode builds & runs on simulator, but App Store upload always fails due to missing entitlement Core Problem: In my Apple Developer “Identifiers → App ID” page, the Live Activity / ActivityKit capability does NOT appear at all, so I cannot enable: Live Activities ActivityKit Third-party activity entitlement Without being able to enable this capability, I cannot create a valid provisioning profile that includes: com.apple.developer.activitykit.allow-third-party-activity Flutter + Xcode insists this entitlement must exist, but Apple Developer portal does not give any option to enable it.

Notarization Issue
Hey there, I'm experiencing an issue with notarization of my macOS application, which is blocking a release. We have signing/notarization hooked up to our CI process, both for prior releases as well as development builds (at the trunk tip). The notarization process has typically taken anywhere from a few minutes to a few tens of minutes, but for our most recent release, it's taking an unreasonably long time. I've compiled the submission info for each build (+ reattempted notarizations) below. What's interesting is that the oldest one was accepted- however, it timed out our CI process, so we never actually released it. Subsequent builds are more or less identical in terms of their content, however, they've been stewing in the notarization process for over 13 hours in some cases. % xcrun notarytool info 67413dae-64f5-4372-972d-e0ac158e18e3 Successfully received submission info createdDate: 2025-04-02T16:28:25.999Z id: 67413dae-64f5-4372-972d-e0ac158e18e3 name: Warp Vault.app.zip status: In Progress % xcrun notarytool info 0c72b243-4a8d-4976-a97b-75689d7e2497 Successfully received submission info createdDate: 2025-04-02T05:49:05.861Z id: 0c72b243-4a8d-4976-a97b-75689d7e2497 name: Warp Vault.app.zip status: In Progress % xcrun notarytool info 8e2edfc2-58bc-4b33-bc8e-078155759a81 Successfully received submission info createdDate: 2025-04-02T05:23:28.870Z id: 8e2edfc2-58bc-4b33-bc8e-078155759a81 name: Warp Vault.app.zip status: In Progress % xcrun notarytool info 8fb17b0c-ace4-4b6f-bef8-68d22696814d Successfully received submission info createdDate: 2025-04-02T05:07:48.187Z id: 8fb17b0c-ace4-4b6f-bef8-68d22696814d name: Warp Vault.app.zip status: Accepted At the time of checking, the UTC date was: % TZ="UTC" date Wed Apr 2 18:42:14 UTC 2025 It's interesting to me that the notarization process is taking this long. We've notarized many development builds (with debugging flags enabled) in the time between our last public release and our attempt to notarize this one. What's more, the original build for this release was notarized within the span of about 15 minutes, but subsequent submissions of the same build have hung for tens of hours. My two questions are: How can I get our pending notarizations "unstuck"?, and To prevent these types of hangs in the future, should I also routinely build/sign/notarize non-debug builds of my application during the development process? Best regards and many thanks, Charlton

Notarization submission times out.
I am currently having issues uploading my app to appstoreconnect.apple.com/notary/ for notarization. It times out after hanging for a while. I get the following error. 13:42:04 "LocalDataTask <D84AED32-B05B-4439-8BDC-40C0F89B89F1>.<1>" 13:42:04 ), NSLocalizedDescription=The request timed out., NSErrorFailingURLStringKey=https://appstoreconnect.apple.com/notary/v2/asp?, NSErrorFailingURLKey=https://appstoreconnect.apple.com/notary/v2/asp?, _kCFStreamErrorDomainKey=4})

Notary service down again?
Is the Notary service unavailable again? The system-status page shows it as being green but I am back to receiving the same error as previously which fixed itself once the notary service went green again and I am unable to notarize and staple my Distribution PKG.

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?

Unable to Staple Notarization Ticket – SSL Certificate Mismatch for oscdn.apple.com
Hello Apple Support, While attempting to staple a notarization ticket for our signed installer package, the stapler command fails with Error 65. Upon investigation, we found that connections to oscdn.apple.com present an SSL certificate issued to a248.e.akamai.net, which does not include oscdn.apple.com in its Subject Alternative Name (SAN). This mismatch prevents our macOS environment from validating tickets and completing the stapling process. Steps tried: Verified notarization status (Accepted). DNS flushed, tried different DNS (8.8.8.8, 1.1.1.1). curl to oscdn.apple.com consistently fails with SSL error 60. Please advise on resolving this certificate mismatch. also when I try to run the stapler command with my pkg "xcrun stapler staple/Users/mactest/Desktop/IPMPlus_Macos_Installer.signed.pkg" getting the output like :- Processing: /Users/mactest/Desktop/IPMPlus_Macos_Installer.signed.pkg Could not validate ticket for /Users/mac-test/Desktop/IPMPlus_Macos_Installer.signed.pkg The staple and validate action failed! Error 65. please help Thank you.

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

Can't run app on iPhone after registered UDID
The device UDID was registered to the developer account 40 hours ago, the STATUS column was "processing" in the first 24 hours, then turned to empty. But I still can't run my app (with distribution method "development"), when I try to run it after download it through my OTA URL, it prompts “the app cannot be installed because its integrity could not be verified” but everything runs good on a iPhone which was registered a month ago. What should I do now? keep waiting?

pkgbuild giving signing identity error
The actual error: pkgbuild: error: Could not find appropriate signing identity for “Developer ID installer: My Name (DeveloperID)”. I'm trying to sign a program written with gfortran. The steps worked the last time (Mar 23) I built this code. The steps to error: a) xcrun notarytool store-credentials --apple-id "xxx" --team-id "yyy" Giving Profile Name zzz and App-specific password b) codesign --force --timestamp --options=runtime -s "Developer ID Application: My Name (yyy)" AppName c) pkgbuild --root ROOT --identifier org.aaa.bbb --version "1.1.1" --sign "Developer ID installer: My Name (yyy)" AppName.pkg ROOT contains the package contents At this point I get the error pkgbuild: error: Could not find appropriate signing identity for “Developer ID installer: My Name (yyy)” Are there steps that have changed. Any suggestions? Thanks, David

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?

Developer ID Notary Service - Outage
I’m unable to notarize the executable and the .app — the status has been showing “In Progress” for over an hour. Upon checking the xcrun logs, it indicates that the submission ID was not received. I also noticed there’s an Apple Developer Service outage reported since October 8, 2025. Could you please let me know when this outage is expected to be resolved? It would be very helpful.

Resolving Tap to Pay on iPhone errors when building for App Store or TestFlight distribution
I am receiving an entitlement error from stripe terminal SDK when integrating Tap to Pay from apple in the info.plist. Im hoping that someone can give me their input on my error output rather than diving into the stripe sdk to point me in the right direction of something I may have missed with entitlements. I have been approved for tap to pay entitlement and am following the instructions here from apple: https://developer.apple.com/documentation/proximityreader/setting-up-the-entitlement-for-tap-to-pay-on-iphone com.apple.developer.proximity-reader.tap-to-pay
