Issue with "NSUserTrackingUsageDescription" Blocking App Update Submission
Hi everyone, I’m currently facing an issue while trying to submit an update for my app to the App Store. The review process is blocking the update due to a "Privacy - Data Use and Sharing" warning, stating that our app requests "tracking purchase history for tracking purposes." However, we have already removed this functionality and deleted the NSUserTrackingUsageDescription key from our latest build. Despite this, the warning persists, and we are unable to proceed with the update. I have already contacted Apple Support, but in the meantime, I wanted to ask the community: Has anyone else encountered this issue, and if so, how did you resolve it? Is there a way to force a refresh of privacy-related settings in App Store Connect? Are there any additional steps we need to take to completely remove this tracking flag from our app submission? Any insights or guidance would be greatly appreciated! Thanks in advance for your help.

Handling ITMS-91061: Missing privacy manifest
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.

iOS 18.3.1 - App shows multiple Face ID checks issue when launched
Our app uses Face ID to optionally secure access to the app for device owner. This not the new 'Require Face ID' feature of iOS 18 - this is our own custom implementation that has some other related logic for authentication handling. Starting in iOS 18.3.1, starting the app results in multiple Face Id checks being fired - sometimes just a couple but sometimes many more. Curiously, this is happening even when I completely disable any code we have that prompts for Face ID. It appears to come from nowhere. This does not happen on prior iOS 18 releases so, while I might be doing something improper in the code, something specific has changed in iOS 18.3.1 to cause this issue to manifest. I'm looking for advice as to what could be occurring here, how to debug a Face Id check that appears to come from nowhere, and what, if any, workarounds exist.

Sign in with Apple Sync Issues Across Teams
We have 2 developers: Developer A created a Bundle ID and configured Sign in with Apple, but didn't create a corresponding App. This Bundle ID is only used for login on our official website. Developer B created a Bundle ID, configured Sign in with Apple, and has a corresponding App. The issue we're encountering is that because these two Bundle IDs are under different teams, when using the same Apple ID to log into these two applications, different accounts are generated. (We've tested that when creating Service IDs under the same team, logging in with Bundle IDs under the same team generates the same account.) Since Developer A's Bundle ID doesn't have a created app, it cannot be transferred to Developer B. Therefore, we'd like to know if there's any way to make the accounts generated from logging in with the same Apple ID be identical across these two teams?

App auto PopUps stopping a text out and call out
Hello, I have created an app for both iOs and Android where upon speaking two trigger words, the listening app sends a text and then calls to an inputted designated phone contact. The Android version works perfectly. The iOs version also works perfectly but the iOs app emiits a PopUp for each, the text and then the call asking "Do you really want to send the text -or- make the call". Basically, I input the contact info and I spoke the trigger words. So, yes I want to send the text and make the call. So, I have to click the two PopUps then the device sends and calls. Is there a way to suppress the PopUps in any way? The app is designed for emergencies. So, a dely to anser a popup is not at all good. Maybe by telling the device to allow auto calls and texts from my app? Any and all help on this issue will be very welcomed... Thanks :)

Issues after app transfer
We recently transferred two applications to a different account, both of which utilize Keychain and shared app containers. Before transferring the first application, we anticipated losing access to the Keychain and took proactive measures by backing up data to the app’s private container in the final release prior to the transfer. During the app transfer process, we removed the shared container group ID from the old account and recreated it under the new account. In our testing, Keychain restoration from the local backup was successful, and users experienced no disruptions. However, after releasing the application, we observed that approximately 25% of our users not only lost their Keychain data as expected but also their shared app container data. As we have been unable to reproduce this issue internally, we are seeking your guidance on how to prevent a similar situation when transferring our second application. At this stage, we have not yet released any updates from the new account, and the Keychain data remains backed up in the app’s private container. We would appreciate any insights or recommendations you can provide to ensure a smooth transition for our users and make sure we can keep the data in shared container.

Keychain Item Invalidation After Interrupted Face ID Reset on iOS 18.3.1
I am working on improving Keychain item storage secured with Face ID using SecAccessControlCreateWithFlags. The implementation uses the .biometryAny flag as shown below: SecAccessControlCreateWithFlags( kCFAllocatorDefault, kSecAttrAccessibleWhenUnlockedThisDeviceOnly, .biometryAny, &amp;error ) While this approach generally works as expected, I encountered a specific edge case during testing. On iOS 18.3.1 with Xcode 15.4, the following sequence causes the Keychain item to become inaccessible: Navigate to Settings &gt; Face ID &amp; Passcode and select Reset Face ID. Before setting up a new Face ID, tap the Back button to exit the setup process. Reopen the Face ID setup and complete the enrollment. Return to the app—previously stored Keychain items protected by .biometryAny are no longer available. This behavior appears to be a change introduced in recent iOS versions. In versions prior to iOS 15, resetting or deleting Face ID entries did not invalidate existing Keychain items protected by .biometryAny. This difference in behavior between iOS versions raises questions about the changes to biometric protection handling. Any suggestions are welcomed that might shine a light on what the best practice to use keychain access control and prevent the data to become unavailable.

How to modify the login right for headless login
Hello -- I am developing an Authentication Plug-in for the purpose of invoking login with no user interaction (headless). There seems to be sufficient documentation and sample code on how to implement a plug-in and mechanism, and debug the same, which is great. What I am trying to understand is exactly how to modify the login right (system.login.console) in order to accomplish my goal. Question 1: I had the idea of installing my mechanism as the first mechanism of the login right, and when invoked to set the username and password into the engine’s context, in the belief that this would negate the system from needing to display the login screen. I didn’t modify or remove any other mechanisms. This did not work, in the sense that the login screen was still shown. Should this work in theory? Question 2: I then tried modifying the login right to remove anything that interacted with the user, leaving only the following: <array> <string>builtin:prelogin</string> <string>builtin:login-begin</string> <string>builtin:forward-login,privileged</string> <string>builtin:auto-login,privileged</string> <string>MyAuthPlugin:customauth,privileged</string> <string>PKINITMechanism:auth,privileged</string> <string>builtin:login-success</string> <string>HomeDirMechanism:login,privileged</string> <string>HomeDirMechanism:status</string> <string>MCXMechanism:login</string> <string>CryptoTokenKit:login</string> </array> The mechanisms I removed were: <string>builtin:policy-banner</string> <string>loginwindow:login</string> <string>builtin:reset-password,privileged</string> <string>loginwindow:FDESupport,privileged</string> <string>builtin:authenticate,privileged</string> <string>loginwindow:success</string> <string>loginwindow:done</string> In place of builtin:authenticate I supplied my own mechanism to verify the user’s password using OD and then set the username and password in the context. This attempt appears to have failed quite badly, as authd reported an error almost immediately (I believe it was related to the AuthEngine failing to init). There’s very little information to go on as to what each of these mechanisms do, and which are required, etc. Am I on the wrong track in attempting this? What would be the correct approach?

Missing privacy manifest
Hi, The email attached states that we need to add GoogleToolboxForMac's missing privacy manifest.

Security Implications of fdesetup authrestart on FileVault-Enabled Macs
I'm looking for confirmation on the security aspects of fdesetup authrestart when used on a FileVault-enabled Mac. As I understand it, this command temporarily stores the decryption key in memory to allow the system to restart without requiring manual entry of the FileVault password. However, I have a few security-related concerns: Storage of the Decryption Key: Where exactly is the key stored during an authenticated restart? Is it protected within the Secure Enclave (for Apple Silicon Macs) or the T2 Security Chip on Intel Macs? Key Lifetime &amp; Wiping: At what point is the decryption key erased from memory? Does it persist in any form after the system has fully rebooted? Protection Against Physical Attacks: If an attacker gains physical access to the machine before the restart completes, is there any possibility that they could extract the decryption key from memory? Cold Boot Attack Resistance: Is there any risk that advanced forensic techniques (such as freezing RAM to retain data) could be used to recover the decryption key after issuing an authenticated restart? Malware Resistance: Could a compromised system (e.g., root access by an attacker) intercept or misuse the decryption key before the restart? I understand that on Apple Silicon and T2-equipped Macs, FileVault keys are tied to hardware-based encryption, making unauthorized access difficult. However, I'd like to confirm whether Authenticated Restart introduces any new risks compared to a standard FileVault-enabled boot process.

ITMS-91061: Missing privacy manifest
I have these two pods: Frameworks/GTMSessionFetcher.framework/GTMSessionFetcher Frameworks/GoogleToolboxForMac.framework/GoogleToolboxForMac they are showing this error: ITMS-91061: Missing privacy manifest I've tried manually making privacy files, I've tried updating the SDK's too. I cant update them because firebase depends on GTM Session at a lower version and if I update, MLKit depends on toolbox (even though its deprecating) If I upgrade then the whole project explodes. What do I do. I need help. this is all I get and it doesn't help: https://developer.apple.com/support/third-party-SDK-requirements

Fraud System Detection - variables recognition
I am currently working on Fraud System Detection that will be used by one of the financial institutions. Those tools are related to ensuring user security. Our goal is to identify features that can trigger an early warning system for attempted fraud. We have identified three uncertain variables: Whether the user is having a conversation while using our app, Whether the user has specific screen sharing apps on their phone, Whether the user has enabled VPN connection. Here my doubts appear: Can we check the presence of a telephone conversation if we are not a VOIP application? Can we check the presence of installed programs using Universal Link and canOpenUrl(_:) method? Can we read "SCOPED" key from CFNetworkCopySystemProxySettings() dictionary? I will be glad for any advice and help.

iOS 18 Password Autofill - In-App Enablement API
Hey everyone, I'm working on a password manager app for iOS and I'm trying to implement the new iOS 18 feature that lets users enable autofill directly from within the app. I know this exists because I've seen it in action in another app. They've clearly figured it out, but I'm struggling to find any documentation or info about the specific API. Has anyone else had any luck finding this? Any help would be greatly appreciated! Thanks in advance!

Import PKCS#12 into macOS login keychain or system keychain
Hello. I want to do the following and need your help. I want to import a certificate (pkcs#12) into my macOS keychain with a setting that prohibits exporting the certificate. I want to import the certificate (pkcs#12) into my login keychain or system keychain. I was able to achieve [1] with the help of the following threads, but have the following problems. https://developer.apple.com/forums/thread/677314?answerId=824644022#824644022 how to import into login keychain or system keychain How to achieve this without using the deprecated API To import into the login keychain, I could use the “SecKeychainCopyDefault” function instead of the “SecKeychainCopySearchList” function, However, both of these functions were deprecated APIs. https://developer.apple.com/documentation/security/seckeychaincopysearchlist(_:) https://developer.apple.com/documentation/security/seckeychaincopydefault(_:) I checked the following URL and it seems that using the SecItem API is correct, but I could not figure out how to use it. https://developer.apple.com/documentation/technotes/tn3137-on-mac-keychains Is there any way to import them into the login keychain or system keychain without using these deprecated APIs?

Sign-up not completed error
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!

Share session from ASWebAuthenticationSession with WKWebView
Hello everyone, In my application, i have implemented authentication using ASWebauthenticationSession. However, when redirecting the user to a WKWebView, no cookies are shared, causing the session to be lost and requiring the user to log in again. Is there a way to share cookies between the two? If not, what would be the best approach to set up authentication that ensures SSO when switching to a WebView ? Thank you very much for your help !

if I skip passkey setup, how long will lapse before I am asked by the OS to register for passkey again
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.
