I was experiencing a weird sign in error when using apple sign in with my app and wanted to put it here for anyone else who might experience it in the future, and so apple can make this requirement more clear.
I was using CloudKit and apple sign in. If you are not using both this probably does not apply to you.
Every time I would go to sign in in the iOS simulator I would enter my password, hit "sign in", and everything just froze.
The very odd reason for this is if you are using iCloudKit and apple sign in you need to go to specifically the "identifiers" in the "Certificates, Identifiers & Profiles" menu (https://developer.apple.com/account/resources/identifiers/list). And from there you specifically need an App ID Configuration with apple sign in enabled.
From there you have to have the same exact bundle identifier in Xcode under project settings(not an upper tab just click your project in the left panel). And that should allow you to both pass validation and have your sign in work.
Hope this helps!

Trying to apply 'always trust' to certificate added to keychain using both SecItemAdd() and SecPKCS12Import() with SecTrustSettingsSetTrustSettings().
I created a launchdaemon for this purpose.
AuthorizationDB is modified so that any process running in root can apply trust to certificate.
let option = SecTrustSettingsResult.trustRoot.rawValue
// SecTrustSettingsResult.trustAsRoot.rawValue for non-root certificates
let status = SecTrustSettingsSetTrustSettings(secCertificate, SecTrustSettingsDomain.admin, [kSecTrustSettingsResult: NSNumber(value: option.rawValue)] as CFTypeRef).
Above code is used to trust certificates and it was working on os upto 14.7.4.
In 14.7.5 SecTrustSettingsSetTrustSettings() returns errAuthorizationInteractionNotAllowed.
In 15.5 modifying authorization db with AuthorizationRightSet() itself is returning errAuthorizationDenied.Tried manually editing authorization db via terminal and same error occurred.
Did apple update anything on Security framework?
Any other way to trust certificates?
My high-level goal is to add support for Game Mode in a Java game, which launches via a macOS "launcher" app that runs the actual java game as a separate process (e.g. using the java command line tool).
I asked this over in the Graphics & Games section and was told this, which is why I'm reposting this here.
I'm uncertain how to speak to CLI tools and Java games launched from a macOS app. These sound like security and sandboxing questions which we recommend you ask about in those sections of the forums.
The system seems to decide whether to enable Game Mode based on values in the Info.plist (e.g. for LSApplicationCategoryType and GCSupportsGameMode). However, the child process can't seem to see these values. Is there a way to change that?
(The rest of this post is copied from my other forums post to provide additional context.)
Imagine a native macOS app that acts as a "launcher" for a Java game.** For example, the "launcher" app might use the Swift Process API or a similar method to run the java command line tool (lets assume the user has installed Java themselves) to run the game.
I have seen How to Enable Game Mode. If the native launcher app's Info.plist has the following keys set:
LSApplicationCategoryType set to public.app-category.games
LSSupportsGameMode set to true (for macOS 26+)
GCSupportsGameMode set to true
The launcher itself can cause Game Mode to activate if the launcher is fullscreened. However, if the launcher opens a Java process that opens a window, then the Java window is fullscreened, Game Mode doesn't seem to activate. In this case activating Game Mode for the launcher itself is unnecessary, but you'd expect Game Mode to activate when the actual game in the Java window is fullscreened.
Is there a way to get Game Mode to activate in the latter case?
** The concrete case I'm thinking of is a third-party Minecraft Java Edition launcher, but the issue can also be demonstrated in a sample project (FB13786152). It seems like the official Minecraft launcher is able to do this, though it's not clear how. (Is its bundle identifier hardcoded in the OS to allow for this? Changing a sample app's bundle identifier to be the same as the official Minecraft launcher gets the behavior I want, but obviously this is not a practical solution.)

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!
Hi Apple Team and Community,
We've encountered a sudden and widespread failure with the App Attest service starting today across multiple production apps and regions. The previously working implementation is now consistently returning the following error on iOS:
The operation couldn’t be completed. (com.apple.devicecheck.error error 4.) (serverUnavailable)
Despite the green status on Apple’s System Status page, this appears to be a backend issue—possibly infrastructure or DNS-related.
Notably:
The issue affects multiple apps.
It is reproducible across different geographies.
No code changes were made recently to the attestation logic.
We previously reported a similar concern in this thread: App Attest Attestation Failing, but this new occurrence seems unrelated to any client-side cause.
Update:
An Apple engineer in this thread(https://developer.apple.com/forums/thread/782987) confirmed that the issue was due to a temporary DNS problem and has now been resolved.
Can anyone else confirm seeing this today? Any insights from Apple would be appreciated to ensure continued stability.
Thanks!
Since Sun 15th Jun 04:30 (UTC+7) we received lots of following error that causes our device test failure. Could Apple please investigate further?
#############################
Operations could not be completed. (com.apple.devicecheck.error error 4.) (serverUnavailable)
Issue Summary
I'm encountering a DCError.invalidInput error when calling DCAppAttestService.shared.generateAssertion() in my App Attest implementation. This issue affects only a small subset of users - the majority of users can successfully complete both attestation and assertion flows without any issues. According to Apple Engineer feedback, there might be a small implementation issue in my code.
Key Observations
Success Rate: ~95% of users complete the flow successfully
Failure Pattern: The remaining ~5% consistently fail at assertion generation
Key Length: Logs show key length of 44 characters for both successful and failing cases
Consistency: Users who experience the error tend to experience it consistently
Platform: Issue observed across different iOS versions and device types
Environment
iOS App Attest implementation
Using DCAppAttestService for both attestation and assertion
Custom relying party server communication
Issue affects ~5% of users consistently
Key Implementation Details
1. Attestation Flow (Working)
The attestation process works correctly:
// Generate key and attest (successful for all users)
self.attestService.generateKey { keyId, keyIdError in
guard keyIdError == nil, let keyId = keyId else {
return completionHandler(.failure(.dcError(keyIdError as! DCError)))
}
// Note: keyId length is consistently 44 characters for both successful and failing users
// Attest key with Apple servers
self.attestKey(keyId, clientData: clientData) { result in
// ... verification with RP server
// Key is successfully stored for ALL users (including those who later fail at assertion)
}
}
2. Assertion Flow (Failing for ~5% of Users with invalidInput)
The assertion generation fails for a consistent subset of users:
// Get assertion data from RP server
self.assertRelyingParty.getAssertionData(kid, with: data) { result in
switch result {
case .success(let receivedData):
let session = receivedData.session
let clientData = receivedData.clientData
let hash = clientData.toSHA256() // SHA256 hash of client data
// THIS CALL FAILS WITH invalidInput for ~5% of users
// Same keyId (44 chars) that worked for attestation
self.attestService.generateAssertion(kid, clientDataHash: hash) { assertion, err in
guard err == nil, let assertion = assertion else {
// Error: DCError.invalidInput
if let err = err as? DCError, err.code == .invalidKey {
return reattestAndAssert(.invalidKey, completionHandler)
} else {
return completionHandler(.failure(.dcError(err as! DCError)))
}
}
// ... verification logic
}
}
}
3. Client Data Structure
Client data JSON structure (identical for successful and failing users):
// For attestation (works for all users)
let clientData = ["challenge": receivedData.challenge]
// For assertion (fails for ~5% of users with same structure)
var clientData = ["challenge": receivedData.challenge]
if let data = data { // Additional data for assertion
clientData["account"] = data["account"]
clientData["amount"] = data["amount"]
}
4. SHA256 Hash Implementation
extension Data {
public func toSHA256() -> Data {
return Data(SHA256.hash(data: self))
}
}
5. Key Storage Implementation
Using UserDefaults for key storage (works consistently for all users):
private let keyStorageTag = "app-attest-keyid"
func setKey(_ keyId: String) -> Result<(), KeyStorageError> {
UserDefaults.standard.set(keyId, forKey: keyStorageTag)
return .success(())
}
func getKey() -> Result<String?, KeyStorageError> {
let keyId = UserDefaults.standard.string(forKey: keyStorageTag)
return .success(keyId)
}
Questions
User-Specific Factors: Since this affects only ~5% of users consistently, could there be device-specific, iOS version-specific, or account-specific factors that cause invalidInput?
Key State Validation: Is there any way to validate the state of an attested key before calling generateAssertion()? The key length (44 chars) appears normal for both successful and failing cases.
Keychain vs UserDefaults: Could the issue be related to using UserDefaults instead of Keychain for key storage? Though this works for 95% of users.
Race Conditions: Could there be subtle race conditions or timing issues that only affect certain users/devices?
Error Recovery: Is there a recommended way to handle this error? Should we attempt re-attestation for these users?
Additional Context & Debugging Attempts
Consistent Failure: Users who experience this error typically experience it on every attempt
Key Validation: Both successful and failing users have identical key formats (44 character strings)
Device Diversity: Issue observed across different device models and iOS versions
Server Logs: Our server successfully provides challenges and processes attestation for all users
Re-attestation: Forcing re-attestation sometimes resolves the issue temporarily, but it often recurs
The fact that 95% of users succeed with identical code suggests there might be some environmental or device-specific factor that we're not accounting for. Any insights into what could cause invalidInput for a subset of users would be invaluable.
In my app, I use SecItem to store some data in the Keychain. I’d like to know — when a user sets up a new iPhone and transfers data from the old device, will those Keychain items be migrated or synced to the new device?
we can get token but when send to verity from apple. it reture Error : {"responseCode":"400","responseMessage":"Missing or incorrectly formatted device token payload"}
Can someone please guide me on the entire process of integrating ads in an IOS application using google's admob sdk? Not related to code but things related to Apple's privacy policy. Which options do need to select or specify in my app profile's privacy policy (identifier) section?
I have 2 basic questions related to Launch Constraints:
[Q1] Are Launch Constraints supposed to work when SIP is disabled?
From what I'm observing, when SIP is disabled, Launch Constraints (e.g. Launch Constraint Parent Process) are not enforced. I can understand that. But it's a bit confusing considering that the stack diagram in the WWDC 2023 session is placing the 'Environment Constraints' block under SIP, not above.
Also the documentation only mentions SIP for the 'is-sip-protected' fact.
[Q2] Is the SpawnConstraint key in legacy launchd plist files (i.e. inside /Library/Launch(Agents|Daemons)) officially supported?
From what I'm seeing, it seems to be working when SIP is enabled. But the WWDC session and the documentation don't really talk about this case.
Hi! We are developing an authentication plugin for macOS that integrates with the system's authentication flow. The plugin is designed to prompt the user for approval via a push notification in our app before allowing access. The plugin is added as the first mechanism in the authenticate rule, followed by the default builtin:authenticate as a fallback.
When the system requests authentication (e.g., during screen unlock), our plugin successfully displays the custom UI and sends a push notification to the user's device. However, I've encountered the following issue:
If the user does not approve the push notification within ~30 seconds, the system resets the screen lock (expected behavior).
If the user approves the push notification within approximately 30 seconds but doesn’t start entering their password before the timeout expires, the system still resets the screen lock before they can enter their password, effectively canceling the session.
What I've Tried:
Attempted to imitate mouse movement after the push button was clicked to keep the session active.
Created a display sleep prevention assertion using IOKit to prevent the screen from turning off.
Used the caffeinate command to keep the display and system awake.
Tried setting the result as allow for the authorization request and passing an empty password to prevent the display from turning off.
I also checked the system logs when this issue occurred and found the following messages:
___loginwindow: -[LWScreenLock (Private) askForPasswordSecAgent] | localUser = >timeout
loginwindow: -[LWScreenLock handleUnlockResult:] _block_invoke | ERROR: Unexpected _lockRequestedBy of:7 sleeping screen
loginwindow: SleepDisplay | enter
powerd: Process (loginwindow) is requesting display idle___
These messages suggest that the loginwindow process encounters a timeout condition, followed by the display entering sleep mode. Despite my attempts to prevent this behavior, the screen lock still resets prematurely.
Questions:
Is there a documented (or undocumented) system timeout for the entire authentication flow during screen unlock that I cannot override?
Are there any strategies for pausing or extending the authentication timeout to allow for complex authentication flows like push notifications?
Any guidance or insights would be greatly appreciated. Thank you!

I have been working on integrate sign in with apple. I failed for a while. So I download the demo app from this link:
https://developer.apple.com/documentation/authenticationservices/implementing-user-authentication-with-sign-in-with-apple
And change the bundle id and add it to my paid apple developer account team.
Then run it and test it on my all device. It always failed with showing sign up not completed and the log like below:

We have integrated Sign in with Apple into our iOS project using the recommended implementation from your documentation,However, we are experiencing issues when testing with the following:
Bundle ID: com.app.xxx
Using real certificates from our Apple Developer account
Issue Details:
On real devices, after entering the Apple ID password, we receive a message saying:
"Sign-up not completed"
On simulators, the flow gets stuck after entering the password no further progress occurs.
We are not receiving any explicit error messages in the console or logs.
We also tested with the official Apple sign-in demo code from the documentation link above, and the same issue occurred.
Our team has confirmed that all necessary configurations have been set correctly, and the same implementation works on other accounts.
We would appreciate your assistance in identifying the root cause and helping us resolve this issue.
Thank you,
When implementing Sign In with Apple I created an App ID and a Service ID for my app. I didn't configure the Server-to-Server Notification URL properly there and token revocation didn't work.
Later on I updated the url config and the name of the identifiers. However, when I Sign in with Apple in my app I still see the old identifier name in my iPhone Settings->Apple Account->Sign in with Apple. I would assume that if the name doesn't update, the configuration doesn't update either.
I'm using automatic Xcode signing, I have deleted all the profiles locally, cleaned project, bumped versions, waited for a week, nothing worked.
Token revocation for account deletion doesn't work properly I would assume because of the initial misconfiguration. I want to mention that this is working fine for my development build (another bundleID, AppID, ServiceID)
What am I missing here?

I am implementing Apple Sign-In for a multi-platform application, specifically for the web component using the REST API flow.
I am encountering an invalid_request Invalid web redirect url error when attempting to use a newly registered redirect URL.
Here are the details:
Original Test URL: I initially registered a redirect URL, let's call it [Your Original Test Redirect URL, e.g., https://test.yourdomain.com/auth/callback], for testing purposes. This URL worked correctly.
New Service URL: I then registered a second redirect URL, [Your New Service Redirect URL, e.g., https://www.yourdomain.com/auth/callback], intended for my production service. This URL was registered approximately 5 days ago (including the weekend).
The Problem: The new service URL ([Your New Service Redirect URL]) is still not working and consistently returns the invalid_request Invalid web redirect url error.
Puzzling Behavior: Furthermore, I have since deleted the original test URL ([Your Original Test Redirect URL]) from the Service ID configuration in the Apple Developer portal. However, the deleted test URL still appears to function correctly when I use it.
This situation is highly confusing: The newly registered URL is not working after 5 days, while the URL I have deleted from the configuration is still operational.
The Service ID in question is [Your Service ID, e.g., com.yourdomain.service].
Could you please investigate why the new redirect URL ([Your New Service Redirect URL]) is not becoming active and is returning the invalid_request error, and also explain why the deleted URL ([Your Original Test Redirect URL]) remains functional?
Any guidance or assistance you can provide to resolve this issue with the new URL would be greatly appreciated.
Thank you for your time and support.
Sincerely,
