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.

I would like to confirm about fraud prevention using Device Check when publishing multiple apps.
If the Team ID and Key ID are the same, will the values be shared across all apps with Device Check?
With Device Check, only two keys can be created per developer account, and these two are primarily intended for key renewal in case of a leak, rather than for assigning different keys to each app, correct?
If both 1 and 2 are correct, does that mean that Device Check should not be used to manage "one-time-only rewards per device" when offering them across multiple apps?
Thank you very much for your confirmation.
During internal testing, we observed the following behavior and would appreciate clarification on whether it is expected and supported in production environments.
When generating an elliptic-curve cryptographic key pair using "kSecAttrTokenIDSecureEnclave", and explicitly specifying a "kSecAttrAccessGroup", we found that cryptographic operations (specifically encryption and decryption) could be successfully performed using this key pair from two distinct applications. Both applications had the Keychain Sharing capability enabled and were signed with the same provisioning profile identity.
Given the documented security properties of Secure Enclave, backed keys, namely that private key material is protected by hardware and access is strictly constrained by design, we would like to confirm whether the ability for multiple applications (sharing the same keychain access group and signing identity) to perform cryptographic operations with the same Secure Enclave–backed key is expected behavior on iOS.
Specifically, we are seeking confirmation on:
Whether this behavior is intentional and supported in production.
Whether the Secure Enclave enforces access control primarily at the application-identifier (App ID) level rather than the individual app bundle level in this scenario.
Whether there are any documented limitations or guarantees regarding cross-application usage of Secure Enclave keys when keychain sharing is configured.
Any guidance or references to official documentation clarifying this behavior would be greatly appreciated.

Hey there,
I’m currently exploring the possibility of integrating Sign in with Apple into my iOS app and backend.
Regarding the iOS app, I’ve read that when a user is signed in, you always need to call getCredentialState on the app’s launch. Is this true? If so, how is it possible to sign the user out then?
I intend to incorporate SwiftData and CloudKit into my application. In light of this, I’m curious about your approach to user management. Specifically, I’m wondering if you would store the user’s data in a Redis database after successful authentication on the backend. Or, would you separate the user data and save it using SwiftData/ CloudKit?
Hey everyone, I'm hitting a really frustrating issue with App Attest. My app was working perfectly with DCAppAttestService on October 12th, but starting October 13th it started failing with DCError Code 2 "Failed to fetch App UUID" at DCAppAttestController.m:153. The weird part is I didn't change any code - same implementation, same device, same everything.
I've tried switching between development and production entitlement modes, re-registered my device in the Developer Portal, created fresh provisioning profiles with App Attest capability, and verified that my App ID has App Attest enabled. DCAppAttestService.isSupported returns true, so the device supports it. Has anyone else run into this? This is blocking my production launch and I'm not sure if it's something on my end or an Apple infrastructure issue.
Hi Apple Developer Team,
I am encountering an issue with the “Sign in with Apple” feature. While implementing this functionality in my dotnet application, I noticed that the user’s first name and last name are not being returned, even though I have explicitly requested the name scope. However, the email and other requested information are returned successfully.
Here are the details of my implementation: 1. Scope Requested: name, email 2. Response Received: Email and other data are present, but fullName is missing or null. 3. Expected Behavior: I expected to receive the user’s first and last name as per the fullName scope.
I have verified the implementation and ensured that the correct scopes are being passed in the request.
Could you please help clarify the following? 1. Are there specific conditions under which Apple may not return the user’s fullName despite the scope being requested? 2. Is there a recommended approach or fallback mechanism to handle this scenario? 3. Could this behavior be related to a limitation or change in the API, or might it be an issue on my end?
I also came to know that for initial sign in the user details will be displayed in the signin-apple payload as Form data but how do I fetch those form-data from the signin-apple request, please suggest
I would greatly appreciate any guidance or solutions to resolve this issue.
Thank you for your support!
Hello! Few month ago i did get hacked on my pc and then my android and iphone. Did get at notice that payments couldent draw. lucky I only had 240kr on lunar card that it did draw 200kr to a gift card. Did get mail from skrill that a account whas created with one of my Gmail’s. Tryed to log them out but window did keep close. Gmail did flag like crazy and wanted me to change pw. how the fuck when I lost control of my phone?!?!??! Just lock it god Damn. let’s make it short! I shared network to pc from my phone With usb. I don’t just think it whas a attacker program as Gmail did flag. I think I did get mirror linked on my android and maybe my iphone. Had a real struggle to reset my pc and phones before it worked. My iPhone drains battery like crazy and feels laggy sometimes. A non registered number whas added to two Gmail’s that they did try to change pw multiple times. did notice I Linux pc activity on my fb and some other stuff. My iphone do reboot still sometimes and every second reboot wifi/bluet can’t be activated and mobile share change pw as the original one did look. Next reboot all work and are the same again. Iam scared that iam still hacked or havent removed him from everything. How can I make sure that Iam still not mirror linked and that he or she can’t access anything? Sorry for the long text but iam scared as fuck.

Hi,
We are trying to open an application "xyz.app"
It worked fine until 15.1.1 versions. But facing issues with 15.2 and 15.3
The application is working fine when we navigate to xyz.app/Contents/MacOS/ and run applet in this directory.
But the error ""Not authorized to send Apple events to Finder"" occurs when we are trying to open the app directly.
Could someone please help me understand what might be causing this issue and how to resolve it?

My app has been rejected by App Store review because the sign in with Apple functionality is not working properly. I'm able to reproduce the issue on my end but I don't understand why it's happening.
I have two other apps that implement the same OAuth flow in an identical manner, and those apps have no issues signing in with Apple.
I've copied my OAuth flow to a fresh project to see if that would make a difference, and it gives me the exact same error. In the simulator I get "invalid_request, invalid web redirect URL", and on-device the FaceID authentication fails with a very non-specific "Sign Up Not Completed" error.
I'm completely out of ideas here, so any guidance would be appreciated. Thanks!
I am using Auth0 as a login manager for our app. The way Auth0 handles login is that their SDK will create a web view where the login is actually handled. Once the login is finished the session will end and the app will gain control. We are not set up for passkeys in their system and can't set up quickly to do that. Unfortunately with the new iOS "passkey is the primary login" way iOS is set up now, users are asked to use passkey when it's not supported on the backend. I don't have direct control of the login screens. Is there any way, at the app level, to tell the app to not use passkeys so that it quits showing up as an option for the users? I can't find any documentation on doing this. How can I stop passkey in my app entirely?

An ITMS-91061: Missing privacy manifest rejection email looks as follows:
ITMS-91061: Missing privacy manifest- Your app includes
"<path/to/SDK>", which includes , an SDK that was identified in the documentation as a privacy-impacting third-party SDK. Starting February 12, 2025, if a new app includes a privacy-impacting SDK, or an app update adds a new privacy-impacting SDK, the SDK must include a privacy manifest file. Please contact the provider of the SDK that includes this file to get an updated SDK version with a privacy manifest. For more details about this policy, including a list of SDKs that are required to include signatures and manifests, visit: https://developer.apple.com/support/third-party-SDK-requirements.
Glossary
ITMS-91061: Missing privacy manifest: An email that includes the name and path of privacy-impacting SDK(s) with no privacy manifest files in your app bundle. For more information, see https://developer.apple.com/support/third-party-SDK-requirements.
: The specified privacy-impacting SDK that doesn't include a privacy manifest file.
If you are the developer of the rejected app, gather the name of the SDK from the email you received from Apple, then contact the SDK's provider for an updated version that includes a valid privacy manifest. After receiving an updated version of the SDK, verify the SDK includes a valid privacy manifest file at the expected location. For more information, see Adding a privacy manifest to your app or third-party SDK.
If your app includes a privacy manifest file, make sure the file only describes the privacy practices of your app. Do not add the privacy practices of the SDK to your app's privacy manifest.
If the email lists multiple SDKs, repeat the above process for all of them.
If you are the developer of an SDK listed in the email, publish an updated version of your SDK that includes a privacy manifest file with valid keys and values.
Every privacy-impacting SDK must contain a privacy manifest file that only describes its privacy practices.
To learn how to add a valid privacy manifest to your SDK, see the Additional resources section below.

Hi Apple Devs,
For our app, we utilize passkeys for account creation (not MFA). This is mainly for user privacy, as there is 0 PII associated with passkey account creation, but it additionally also satisfies the 4.8: Login Services requirement for the App Store.
However, we're getting blocked in Apple Review. Because the AASA does not get fetched immediately upon app install, the reviewers are not able to create an account immediately via passkeys, and then they reject the build.
I'm optimistic I can mitigate the above. But even if we pass Apple Review, this is a pretty catastrophic issue for user security and experience. There are reports that 5% of users cannot create passkeys immediately (https://developer.apple.com/forums/thread/756740). That is a nontrivial amount of users, and this large of an amount distorts how app developers design onboarding and authentication flows towards less secure experiences:
App developers are incentivized to not require MFA setup on account creation because requiring it causes significant churn, which is bad for user security.
If they continue with it anyways, for mitigation, developers are essentially forced to add in copy into their app saying something along the lines of "We have no ability to force Apple to fetch the config required to continue sign up, so try again in a few minutes, you'll just have to wait."
You can't even implement a fallback method. There's no way to check if the AASA is available before launching the ASAuthorizationController so you can't mitigate a portion of users encountering an error!!
Any app that wants to use the PRF extension to encrypt core functionality (again, good for user privacy) simply cannot exist because the app simply does not work for an unspecified amount of time for a nontrivial portion of users.
It feels like a. Apple should provide a syscall API that we can call to force SWCD to verify the AASA or b. implement a config based on package name for the app store such that the installation will immediately include a verified AASA from Apple's CDN. Flicking the config on would require talking with Apple. If this existed, this entire class of error would go away.
It feels pretty shocking that there isn't a mitigation in place for this already given that it incentivizes app developers to pursue strictly less secure and less private authentication practices.

Passkeys in iCloud Keychain
Please help me clarify the current situation regarding the necessity of a privacy manifest file in 3rd party SDKs. It would be nice to have a reply from someone working at Apple, to have a reliable answer.
A quick summery of the events from last year
https://developer.apple.com/support/third-party-SDK-requirements/ : "Starting in spring 2024, you must include the privacy manifest for any SDK listed below when you submit new apps in App Store Connect that include those SDKs, or when you submit an app update that adds one of the listed SDKs as part of the update."
Last autumn, we started receiving warning emails from Apple after initiating app reviews, even when our apps did not have a newly added SDK:
ITMS-91061: Missing privacy manifest - Starting November 12, 2024, if a new app includes a privacy-impacting SDK, or an app update adds a new privacy-impacting SDK, the SDK must include a privacy manifest file. Please contact the provider of the SDK that includes this file to get an updated SDK version with a privacy manifest.
According to this warning message, app updates which do not contain any new SDKs are still not affected.
Since then, at one point in time the deadline changed, as now we have February 12, 2025 in the privacy manifest documentation: https://developer.apple.com/documentation/bundleresources/adding-a-privacy-manifest-to-your-app-or-third-party-sdk
However, this page does not contain any mention of the circumstances, it only states in general that
apps you submit for review in App Store Connect must contain a valid privacy manifest file for a certain number of commonly used third-party SDKs.
My questions
Does the February deadline apply to every app update, even if they do not contain any newly added SDKs? Or does it still affect only the app updates "that adds one of the listed SDKs as part of the update." ? If the former, the 3rd party requirements page should be updated in my opinion. And if the latter, why does the documentation not contain this important piece of information?
We have a basic product which then gets customised for the clients so we upload several different apps based on the same code with the same dependencies. How is it possible that during autumn, Apple sent ITMS-91061: Missing privacy manifest warnings for some of our apps, but did not send it for others? Does Apple not validate all the apps but only some of them randomly? Also, the warning still states that it should be relevant if "an app update adds a new privacy-impacting SDK", but that was not the case for us, we did not add anything newly to our apps - why did we even get these warnings then?
Just in general: when the deadlines change, is there any channel where Apple communicates these, besides the warning emails? I did not see any posts on the Apple Developer site's News page about this February date, I just found it by accident. I don't even remember seeing a notice about the original November deadline, we just started receiving the email warnings without expecting them.
Thank you in advance for anyone sharing an answer.
Pretty much the headline. the func transactionHistory() needs to return the transaction location. This seems so rudimentary, yet it is missing from the docs. Unless I'm missing something, please add this feature or point me in the right direction.
Alternatively, is there a way for my app to get notified of the transaction immediately as it happens? I have to get transactions historically which leaves me with no way to determine where they happened in the past.

Hi,
I've recently tested my custom AuthorizationPlugin on macOS 15 (Sequoia) and I'm seeing a significant change in rendering (or precisely not rendering) the control returned by my SFAuthorizationPluginView's subclass' viewForType method comparing to macOS 14. (I developed and tested my solution on macOS 14 earlier this year).
I use SFAuthorizationPluginView to present a NSView (Custom view) which contains a NSSecureTextField and a NSImageView. I show my custom plugin after the user successfully entered username and password (or only the password if the List of Users is configured in System Settings) into the builtin fields provided by loginwindow:login, so injecting my plugin:mechanism pair into the system.login.console after loginwindow:success. (I need to run my mechanism after builtin:authenticate,privileged since my plugin relies on the authentication result coming from my custom PAM module).
This setup now however doesn't seem to be working: after entering the (username and) password, the circular spinner appears and my NSView never gets rendered. I've found a workaround to place my plugin:mechanism pair after loginwindow:done, so in the end of the whole authorization chain.
I tried to run the good old NameAndPassword bundle, injecting it into the place of the loginwindow:login. Controls are being rendered correctly, but if I place it even right after loginwindow:login it doesn't get rendered as my custom plugin.
Is anybody aware if there's anything has intentionally been changed in macOS 15? Or may it be a bug? I guess the original intention of the SFAuthorizationPluginView class was to overwrite/redefine the UI instead of the builtin username + password field, so if I look at it that way it's expected that the view it contains only gets rendered if we use it instead of loginwindow:login. On the other hand this hasn't been the case until now.
Thanks for any help!
