When developing and testing using my phone I got prompted for allowing app tracking. I later uploaded a build to TestFlight, deleted the old testing app and installed the TestFlight build. I am now stuck in an infinite loop of not getting prompted for allowing app tracking for the app. When entering the app settings the toggle for tracking never appears which leaves me not able to enter the app's content. My guess is that the prompt can only be shown once for the app bundle, but there has to be a way for me to get prompted again without changing the app bundle id. Help is appreciated since this app is scheduled to be published in a week.

https://developer.apple.com/documentation/apptrackingtransparency/attrackingmanager/authorizationstatus/notdetermined Note: Discussion If you call ATTrackingManager.trackingAuthorizationStatus in macOS, the result is always ATTrackingManager.AuthorizationStatus.notDetermined. So, does macOS support getting ATT?

I am currently unable to enable passkey in my app so I am having to tell my users to skip the prompts for using passkey. We have noticed that after a few times of this the OS will stop asking the user to register their passkey. The question is, how long does this last before the OS asks you to use passkey again? Is it permanent until you re-install the app? Just looking for a time frame if anyone knows.

I have implemented "Sign in With Apple" in my app , but problem is when user logged in initially or first time and email I can retrieve , name and email but after that when i tried to re login it is giving null value for name and email, why it is happening and what should be done here?

Hello Apple Developer Community, We have been experiencing a persistent notification issue in our application, Flowace, after updating to macOS 15 and above. The issue is affecting our customers but does not occur on our internal test machines. Issue Description When users share their screen using Flowace, they receive a repetitive system notification stating: "Flowace has accessed your screen and system audio XX times in the past 30 days. You can manage this in settings." This pop-up appears approximately every minute, even though screen sharing and audio access work correctly. This behavior was not present in macOS 15.1.1 or earlier versions and appears to be related to recent privacy enhancements in macOS. Impact on Users The frequent pop-ups disrupt workflows, making it difficult for users to focus while using screen-sharing features. No issues are detected in Privacy & Security Settings, where Flowace has the necessary permissions. The issue is not reproducible on our internal test machines, making troubleshooting difficult. Our application is enterprise level and works all the time, so technically this pop only comes after a period of not using the app. Request for Assistance We would like to understand: Has anyone else encountered a similar issue in macOS 15+? Is there official Apple documentation explaining this new privacy behavior? Are there any interim fixes to suppress or manage these notifications? What are Apple's prospects regarding this feature in upcoming macOS updates? A demonstration of the issue can be seen in the following video: https://youtu.be/njA6mam_Bgw Any insights, workarounds, or recommendations would be highly appreciated! Thank you in advance for your help. Best, Anuj Patil Flowace Team

News link: https://developer.apple.com/news/?id=12m75xbj If your app offers Sign in with Apple, you’ll need to use the Sign in with Apple REST API to revoke user tokens when deleting an account. I'm not good English. I'm confused about the above sentence Do I have to use REST API unconditionally or can I just delete to the account data?

can i get transferid by /auth/usermigrationinfo api before transfered app? https://developer.apple.com/documentation/sign_in_with_apple/transferring-your-apps-and-users-to-another-team#Generate-the-transfer-identifier

"Our app has absolutely no integration with DiDi login. We only integrate WeChat, QQ, carrier, and Apple ID login, and all related login entry icons are local resources. On an iPhone 16 Pro Max device with iOS system version 18.7, there was one isolated incident where the Apple ID login entry icon mysteriously changed to the DiDi app icon. What could be the possible iOS system-level causes for this?"

I have a macOS package (.pkg) that checks for installed Java versions on the machine during the preinstall phase using a preinstall script. If the required Java version is not found, the script displays a message using osascript as shown below. /usr/bin/osascript -e 'tell application "Finder"' -e 'activate' -e 'display dialog "Java Development Kit (JDK) 11 is required" buttons{"OK"} with title "Myprod Warning"' -e 'end tell' So far, no issues have been observed with the installation of my package on all versions of macOS. However, on macOS 15.2, the installation is failing with a "Not authorized to send Apple events to Finder" error. Could someone please help me understand what might be causing this issue and how to resolve it?

Hi, I'm looking at adding App Attest to an app, and I think I understand the mechanics of the attestation process, but I'm having trouble figuring out how development and testing are supposed to work. Two main questions: The "App Attest Environment" -- the documentation says that attestation requests made in the .development sandbox environment don't affect the app's risk metrics, but I'm not sure how to actually use this sandbox. My understanding is that one of the things App Attest does is to ensure that your app has been appropriately signed by the App Store, so it knows that it hasn't been tampered with. But the docs say that App Store builds (and Test Flight and Developer Enterprise Program) always use the .production environment. Does App Attest actually work for local developer-build apps if you have this entitlement set? Presumably only on hardware devices since it requires the Secure Enclave? Does our headend have to do something different when verifying the public key and subsequent attested requests for an app that's using the .development sandbox? The docs do mention that a headend server should potentially track two keys per device/user pair so that it can have a production and development key. How does the headend know if a key is from the sandbox environment? Thanks!

In iOS 18, i use CNContactPickerViewController to access to Contacts (i know it is one-time access). After first pick up one contact, the Setting > Apps > my app > Contacts shows Private Access without any option to close it. Is there any way to close it and undisplay it ? I tried to uninstall and reinstall my app, but it didn't work.

Hi, my app is receiving all keyboard events through Input Monitoring preference. It completely stopped to work on macOS 15 Sequoia and I have no idea why. Where can I read what has been changed in Input Monitoring? Thanks!

Trying to make a new developer account but says I cannot. Here are the variables. I have a personal icloud account, it was tied to a developer organization account for an app and company I shut down. I let that developer account expire. Both tied to my mobile number. I can access it but cannot do anything. Trying to setup a new organization developer account using that mobile phone number, but it will not let me create the account. (have a new app/company) Used a different phone number and still got the message that I could not create a new account at this time.

We recently deployed Attestation on our application, and for a majority of the 40,000 users it works well. We have about six customers who are failing attestation. In digging through debug logs, we're seeing this error "iOS assertion verification failed. Unauthorized access attempted." We're assuming that the UUID is blocked somehow on Apple side but we're stumped as to why. We had a customer come in and we could look at the phone, and best we can tell it's just a generic phone with no jailbroken or any malicious apps. How can we determine if the UUID is blocked?

Hi Community, We've implemented Sign In with Apple in our application. Our domains are properly registered in the developer console, but we're experiencing inconsistent email functionality with Apple's privacy email service. Some domains work correctly while others show delivery problems, even though all domains have identical configurations. Apple's console displays green verification status for all domains, yet testing reveals that emails to privacy-protected accounts don't arrive as expected. We're using SendGrid as our email service provider, and all domains have valid authentication records (SPF, DKIM, DMARC) in place. Has anyone encountered similar inconsistencies with Apple's privacy email service? Would appreciate any configuration tips or troubleshooting guidance. Thanks.

I'm trying to use ASWebAuthenticationSession on macOS but there is a weird crash and I have no idea what to do.

Current Setup: Using Secure Enclave with userPresence access control Foreground keychain accessibility: whenPasscodeSetThisDeviceOnly Security Requirement: Our security group wants us to invalidate biometrics and require a username/password if a biometric item is added (potentially by a hostile 3rd party) Need to upgrade from userPresence to biometricCurrentSet to ensure re-authentication when biometric credentials change. Issue: After implementing biometricCurrentSet, authentication cancels after two failed biometric attempts instead of falling back to passcode. Current Detection Method: User completes initial biometric authentication Biometric changes occur (undetectable by app) App attempts Secure Enclave access Access denial triggers re-authentication requirement Cannot revoke refresh token after access is denied Security Concern: Current implementation allows new biometric enrollments to access existing authenticated sessions without re-verification. Question: What's the recommended approach to: Implement biometricCurrentSet while maintaining passcode fallback Properly handle refresh token invalidation when biometric credentials change Looking for guidance on best practices for implementing these security requirements while maintaining good UX.

Hi, A certificate imported on macOS 15 using the security command with the "non-exportable" option was imported in an exportable state. I would like to know how to change this certificate to be non-exportable. Regards, CTJ

I'm experiencing an issue with Sign In with Apple integration in my React Native Expo app (Bundle ID: com.anonymous.TuZjemyApp). Problem Description: When users attempt to sign in using Sign In with Apple, they successfully complete Face ID/password authentication, but then receive a "Sign-Up not completed" error message. The authentication flow appears to stop at this point and doesn't return the identity token to my app. Technical Details: Frontend Implementation: Using expo-apple-authentication. Requesting scopes: FULL_NAME and EMAIL App is properly configured in app.json with: usesAppleSignIn: true Entitlement: com.apple.developer.applesignin Backend Implementation: Endpoint: POST /api/auth/apple Using apple-signin-auth package for token verification Verifying tokens with audience: com.anonymous.TuZjemyApp Backend creates/updates user accounts based on Apple ID Question: I'm not sure why the authentication flow stops with "Sign-Up not completed" after successful Face ID verification. The identity token never reaches my app. Could you please help me understand: What might cause this specific error message? Are there any additional Apple Developer Portal configurations required? Could this be related to app capabilities or entitlements? Is there a specific setup needed for the app to properly receive identity tokens? I set up provisioning profiles, and added Sign in with Apple as a capability and still it doesn't work.

After the App transfer is initiated, will the replacement of the old and new certificates affect user authorization? (Based on some replies from DTS on the forum [Apple login authorization data is generated in combination with the team ID to which the App currently belongs], it is speculated that after the App transfer, during the period when the certificate configuration of the new team ID is not completed, authorization or authentication may not be performed normally, resulting in users being unable to use the Apple login function normally) During the 60-day migration period, if the user authorizes or cancels authorization and then authorizes again in the old app, will the authorized data be different? If so, will transfer_sub be included in the authorization operation?
