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.

I’m having an issue with my Credential Provider Extension for passkey registration. On the browser I click on registration, in IOS i can select my App for passkey registration with a continue button. Wenn I click the continue button the prepareInterface(forPasskeyRegistration:) function is called but the MainInterface is not shown —it only appears when I click the continue button a second time.
Here’s a simplified version of my prepareInterface method:
override func prepareInterface(forPasskeyRegistration registrationRequest: ASCredentialRequest) {
guard let request = registrationRequest as? ASPasskeyCredentialRequest,
let identity = request.credentialIdentity as? ASPasskeyCredentialIdentity else {
extensionContext.cancelRequest(withError: ASExtensionError(.failed))
return
}
self.identity = identity
self.request = request
log.info("prepareInterface called successfully")
}
In viewDidAppear, I trigger FaceID authentication and complete the registration process if register is true. However, the UI only shows after a second “Continue” tap.
Has anyone encountered this behavior or have suggestions on how to ensure the UI appears immediately after prepareInterface is called? Could it be a timing or lifecycle issue with the extension context?
Thanks for any insights!
I have a project with a single app target that serves two environments, and two schemes, one for each env, using xcconfig files for defining environment-specific stuff.
I'm trying to figure this out for months, so I've tried multiple approaches throughout this period:
Have a single domain in "Associated domains" in Xcode, defined as webcredentials:X where X gets replaced using a value from xcconfig.
Have two domain entries in "Associated domains" webcredentials:PROD_DOMAIN and webcredentials:STAGING_DOMAIN.
Have a different order of domains
Results are very interesting: whatever I do, whatever approach I take, password autofill works on staging, but doesn't work on production. I'm aware that we need to test production on Test Flight and AppStore builds. That's how we're testing it, and it's not working. Tested on multiple devices, on multiple networks (wifi + mobile data), in multiple countries.. you name it.
The server side team has checked their implementation a dozen times; it's all configured properly, in the exact same way across environments (except bundle ID, ofc).
We tried a couple websites for validating the apple-app-site-association file, and while all of those are focused on testing universal links, they all reported that the file is configured properly. Still, password autofill doesn't work.
I prefer not to share my app's domains publicly here. Ideally I would contact Apple Developer Support directly, but they now require a test project for that, and since 'a test project' is not applicable to my issue, I'm posting here instead.
We have a crash on DCDevice.current.isSupported
We want to try to make a serial queue to generate tokens but the side effect would be the same token would be used on multiple server API requests that are made within a few ms of each other?
Is this safe or will the Apple server immediately reject the same token being reused?
Can you share how long tokens are safe to use for?
Here is the code we want to try
final actor DeviceTokenController: NSObject {
static var shared: DeviceTokenController = .init()
private var tokenGenerationTask: Task<Data?, Never>?
var ephemeralDeviceToken: Data? {
get async {
// Re-using the token for short periods of time
if let existingTask = tokenGenerationTask {
return await existingTask.value
}
let task = Task<Data?, Never> {
guard DCDevice.current.isSupported else { return nil }
do {
return try await DCDevice.current.generateToken()
} catch {
Log("Failed to generate ephemeral device token", error)
return nil
}
}
tokenGenerationTask = task
let result = await task.value
tokenGenerationTask = nil
return result
}
}
}
I am trying to setup remote Java debugging between two machines running macOS (15.6 and 26).
I am able to get the Java program to listen on a socket. However, I can connect to that socket only from the same machine, not from another machine on my local network. I use nc to test the connection. It reports Connection refused when trying to connect from the other machine.
This issue sounds like it could be caused by the Java program lacking Local Network system permission. I am familiar with that issue arising when a program attempts to connect to a port on the local network. In that case, a dialog is displayed and System Settings can be used to grant Local Network permission to the client program. I don't know whether the same permission is required on the program that is receiving client requests. If it is, then I don't know how to grant that permission. There is no dialog, and System Settings does not provide any obvious way to grant permission to a program that I specify.
Note that a Java application is a program run by the java command, not a bundled application. The java command contains a hard-wired Info.plist which, annoyingly, requests permission to use the microphone, but not Local Network access.
Hello,
I’m storing some values in the Keychain with the attribute ‘ksecattraccessibleafterfirstunlockthisdeviceonly’ (https://developer.apple.com/documentation/security/ksecattraccessibleafterfirstunlockthisdeviceonly).
When I migrate user data between iPhones via iCloud, this behaves as expected and the keys are not preserved.
However, when I migrate using a direct connection between two devices, the keys are preserved, which seems to contradict the attribute’s intent.
Is this a known behavior, and if so, is there a workaround?

We are developing an app that uses Authentication Services to authenticate users. According to the documentation, this framework will open the default web browser if it supports auth session handling, and Safari otherwise. This is not entirely true, and users will be frustrated!
macOS version: Sequoia 15.5; Safari version: 18.5.
When:
The default browser is not Safari, and supports auth session handling (Google Chrome and Microsoft Edge as examples); and -
The Safari app is already running;
The auth flow will:
Present the confirmation dialog box with the default browser icon. Good!
Open a Safari window, instead of the default browser's one. Bad!
Respond with "User Cancelled" error to the app, after making the end user believe the auth was good. Very Bad!!
If the app retries the auth session, the default browser window will open as expected, and it will work as expected.
However, requiring users to authenticate twice is a very bad users experience...
This issue does not reproduce, when either:
Safari is not running at the moment of auth session start;
The default browser does not support auth session handling; or -
Safari is the default browser.
Fellow developers, be warned!
Apple engineers, feedback #18426939 is waiting for you.
Cheers!
Recently, we received an user enquiry regarding the inability to perform bookings for the app.
After investigation, we found that the issue appears to be caused by the failure of the Apple DeviceCheck service.
Based on our checks, approximately 0.01% of requests fail each day (e.g., on 26 June: 6 failures out of 44,544 requests) when using Apple DeviceCheck.
Could you please assist in raising the following enquiries with Apple Support?
What is the typical failure rate of Apple DeviceCheck? Are there any reliability metrics or benchmarks for its performance?
How can the failures be prevented, or is there a recommended retry mechanism to handle such failures?
Does the iOS version affect the performance or reliability of Apple DeviceCheck? Are there known issues or limitations with specific iOS versions?
How long does the token remain valid, and when should a new one be retrieved?
Does using a jailbroken device affect the functionality of Apple DeviceCheck?
Hi,
We are using the MSAL library to authenticate users, with SSO authentication implemented through the Microsoft Authenticator app.
The problem is that once or twice a day, a prompt for forced authentication appears, indicating that silent token acquisition is failing and resulting in a requirement for forced authentication. Below are some of the logs:
=================================================
2025-08-28 11:00:05.034 [Info] [AppDelegate.swift:121] application(:didFinishLaunchingWithOptions:) > MSAL message: TID=751353 MSAL 1.8.1 iOS 18.5 [2025-08-28 10:00:05 - EC9D1457-2D70-4878-926F-553391EBC9D3] [MSAL] Silent flow finished. Result (null), error: -51115 error domain: MSIDErrorDomain
2025-08-28 11:00:05.034 [Info] [AppDelegate.swift:121] application(:didFinishLaunchingWithOptions:) > MSAL message: TID=751353 MSAL 1.8.1 iOS 18.5 [2025-08-28 10:00:05 - EC9D1457-2D70-4878-926F-553391EBC9D3] [MSAL] acquireTokenSilent returning with error: (MSALErrorDomain, -50002) Masked(not-null)
====================================================
We initially raised this issue with Microsoft, but according to them:
In the app's logs, the single one failure it contains, was when the SSO extension returned the error com.apple.AuthenticationServices.AuthorizationError, -6000 during a silent call. This error code is generated by the system framework (Apple), not by our code. It indicates that the framework encountered an unexpected internal issue before or after calling the SSO extension.
MSAL returning interaction_required to the client app is the most effective way to recover from this error (as you mention, after the user selects the account the app continues working as expected).
Additionally, as you also mention, the interactive call is made by switching to Authenticator (not displaying a "window" without leaving Eva Lite app), which means MSAL is not able to use the SSO extension and is using the fallback to legacy authentication.
The recommended next step is for the customer to request support directly from Apple as this is an issue on their side. Additionally, the customer can also try to update to the latest iOS, in case Apple has already fixed this issue.
=============================================
STEPS TO REPRODUCE
There is no such steps its just that this is an enterprise application which is getting used on managed devices[iPhone 14]. The device are managed using some intune policy.
Platform and Version:
iOS
Development Environment: Xcode 15, macOS 13.6.1
Run-time Configuration: iOS 18
Please let me know if there are any solutions to resolve this problem. Thank you.
Hello everyone,
I'm working on a project where I intend to use Secure Enclave-based, device-bound private keys within a Webauthn flow. I have the following question:
Is it possible to generate private keys in the Secure Enclave with integrated attestation in order to reliably prove to a relying party the authenticity and uncompromised state of the key?
If so, I would appreciate details on the implementation—specifically, any prerequisites, limitations, or particular API calls and configuration options that need to be considered.
I look forward to any advice, best practices, or pointers to further documentation on this topic.
Thank you in advance for your support!
Best regards,
Alex

Hi.
We are writing to report a critical issue we've encountered following the recent release of iOS 26 beta 6.
After updating our test devices, we discovered that our application is no longer able to establish HTTPS connections to several of our managed FQDNs. This issue was not present in beta 5 and appears to be a direct result of changes introduced in beta 6.
The specific FQDNs that are currently unreachable are:
d.socdm.com
i.socdm.com
tg.scodm.com
We have reviewed the official iOS & iPadOS 26 Beta 6 Release Notes, particularly the updates related to TLS. While the notes mention changes, we have confirmed that our servers for all affected FQDNs support TLS 1.2, so we believe they should still be compliant.
We have also investigated several of Apple's support documents regarding TLS connection requirements (e.g., HT214774, HT214041), but the information does not seem to apply to our situation, and we are currently unable to identify the root cause of this connection failure.
https://support.apple.com/en-us/102028
https://support.apple.com/en-us/103214
Although we hope this issue might be resolved in beta 7 or later, the official release is fast approaching, and this has become a critical concern for us.
Could you please provide any advice or insight into what might be causing this issue? Any guidance on potential changes in the networking or security frameworks in beta 6 that could affect TLS connections would be greatly appreciated.
We have attached the relevant code snippet that triggers the error, along with the corresponding Xcode logs, for your review.
Thank you for your time and assistance.

Binary code is associated with the NSUserTrackingUsageDescription deleted at present, but in the revised App privacy will contain NSUserTrackingUsageDescription, I feel very confused, don't know should shouldn't solve.
To use passkeys, you need to place the correct AASA file on the web server and add an entry in the Entitlements.plist, for example webcredentials:mydomain.com.
This is clear so far, but I would like to ask if it's possible to set this webcredentials in a different way in the app?
The reason for this is that we are developing a native app and our on-premise customers have their own web servers. We cannot know these domains in advance so creating a dedicated app for each customer is not option for us.
Thank you for your help!

Passkeys in iCloud Keychain
We use Jamf Blueprint to deploy the managed app and identity to the iOS device (iOS 26.3 installed). Our managed app can access the identity via
let identityProvider = ManagedAppIdentitiesProvider()
let identity: SecIdentity
do {
identity = try await identityProvider.identity(withIdentifier: "myIdentity")
} catch { }
However, the app extension cannot access the same identity. Our app extension is notification extension that implemented UNNotificationServiceExtension APIs. We use above code in didReceive() function to access identity that always failed.
The MDM configuration payload is:
"AppConfig": {
"Identities": [
{
"Identifier": "myIdentity",
"AssetReference": "$PAYLOAD_2"
}
]
},
"ExtensionConfigs": {
"Identifier (com.example.myapp.extension)": {
"Identities": [
{
"Identifier": "myIdentity",
"AssetReference": "$PAYLOAD_2"
}
]
}
},
"ManifestURL": "https://example.net/manifest.plist",
"InstallBehavior": {
"Install": "Required"
}
}
Is there any problem in our MDM configuration? Or the notification extension cannot integrate with ManagedApp FM?
Hello Apple Developer Support,
I am experiencing an issue with Apple Sign-In and Private Relay across two separate organizations.
I have a web application that supports Apple Sign-In, configured under organization ID: 62P86SVLK4. Users can log in using their Apple accounts with the Hide My Email (Private Relay) feature enabled. This web application was created a long time ago and initially only had a web component.
Recently, we developed a native mobile version of this application, which also supports Apple Sign-In. However, due to business constraints, the mobile application was created under a different organization ID: T6JT35U9NW.
The Issue
Since the web and mobile applications are registered under different organizations, accounts created using Apple Sign-In with Private Relay are not recognized across both applications.
For example:
A user creates an account in the web app using Apple Sign-In with Private Relay.
When they attempt to log in to the mobile app with Apple Sign-In (also using Private Relay), authentication fails because the generated Private Relay email addresses do not match between the two organizations.
Question
Is there any way to link Private Relay accounts across these two organizations so that users who signed up on the web application can log in to the mobile application seamlessly?
I appreciate any guidance on how to resolve this issue.
Best regards,
Kamil Gronert
I have filed bug reports on this to no avail, so I am bringing it up here hoping someone at Apple will address this. Since the first beta of 26.3, with voice control enabled there are now two icons in the menu bar (*plus an orange dot in full screen) that never go away. That orange microphone isn't serving its intended purpose to notify me that something is accessing my microphone if it is always displayed. I use voice control extensively, so it is nearly always on. In every prior version of macOS, the orange icon was not on for voice control. Even if voice control is not listening but simply enabled in system settings, the orange icon will be there. And there is no need for this icon to be on for a system service that is always listening. This orange icon in the menu bar at all times is incredibly irritating, as it takes up valuable space to the right of the notch, and causes other actual useful menu bar items to be hidden. As well, if some other application on my system were to turn on the mic and start recording me I would never know since that orange icon is always on. It also places an orange dot next to the control center icon taking up even more of the precious little menu bar real estate. Please fix this! Either exempt voice control (as Siri is always listening and it doesn't get the orange icon) or exempt all system services, or give me a way to turn this off. If you cannot tell, I find this incredibly annoying and frustrating.

Hey all,
Question for the masses....
Does the Yubikey authentication have a OS dependency and it only works with a stable, public OS? Does Azure/Okta/Yubikey beta OS26?
My CEO installed iPadOS 26 on his iPad and was not able to authenticate via Yubikey into our company environment. I ran the same scenario on my iPad using iPadOS 26 and I had the same results. Downgrading to iPAdOS doesn't pose these issues.
I'm assuming something isn't fine-tuned yet?
Since release of 18.4. prepareInterfaceToProvideCredential .oneTimeCode case is not called and instead prepareInterfaceForUserChoosingTextToInsert() is called. That is the wrong delegate for this case and it causes confusion for the users.
Also, some TOTP fields are recognised however, the key icon button is not presented above the keyboard next to TOTP suggestions.
I've also tested 18.5 and it has the same issue.
provideOneTimeCodeWithoutUserInteraction works just fine.
Hello Team, We’ve recently started receiving reports from our customer base (Trellix) regarding issues with Full Disk Access (FDA) for Trellix binaries on macOS devices running Tahoe 26.1 (released on November 3, 2025).
The issue occurs when users attempt to add Trellix CLI binaries under FDA to grant the required permissions; the binaries fail to appear under the FDA settings, even after selection.
Upon further investigation, this appears to be a macOS 26.1–specific issue and not observed in earlier versions. Similar reports have been noted across various forums, indicating that the issue affects multiple binaries, not just Trellix:
Some of the discussions on the same issue I see online.

I have also logged FB21009024 for the same. We would like to understand when we can expect this to be fixed, since the issue persists even in 26.2 Beta and also whether the workaround of dragging and dropping the binaries can still be suggested?

We are currently trying to fix a bug when using SignIn with Apple. It appears that on some occasions we are not receiving a user's profile info (name, email) when a new account is created.
After doing some investigation we believe this bug is due to the same Apple login being used as an already deleted account. ASF only appears to send profile info the very first time an Apple login is used. If that account is deleted and another is created with the same apple login we won't receive the profile info.
As a result we are not in compliance with Apple's guidelines requiring that we use the provided profile info with Apple SigIn, and need to prompt users to enter it again.
Is there a process in place to properly "clear" a user after their account is deleted in our system, so that the next time a user creates an account with the same Apple login, we receive their profile info again?
