Application with identifier is not associated with domain
Hi, This issue is happening during Passkey creation. We’ve observed that approximately 1% of our customer users encounter a persistent error during Passkey creation. For the vast majority, the process works as expected. We believe our apple-app-site-association file is correctly configured, served directly from the RP ID over HTTPS without redirects, and is up-to-date. This setup appears to work for most users, and it seems the Apple CDN cache reflects the latest version of the file. To help us diagnose and address the issue for the affected users, we would appreciate guidance on the following: What tools or steps does Apple recommend to identify the root cause of this issue? Are there any known recovery steps we can suggest to users to resolve this on affected devices? Is there a way to force a refresh of the on-device cache for the apple-app-site-association file? Thank you in advance for any input or guidance.

Enquiry about the Apple DeviceCheck service
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?

com.apple.devicecheck.error 0 - DeviceCheck
Dear Apple Developer Support, We are currently encountering a recurring issue with the DeviceCheck API across multiple devices in our production environment. The following error is frequently returned: com.apple.devicecheck.error 0 We would like to ask the following: What are the possible underlying causes that could lead to this specific error code (0) in the DeviceCheck API? Is there any known behavior or condition where Wi-Fi network configurations (e.g., DNS filtering, proxy settings, captive portals) could result in this error? Are there known timeouts, connectivity expectations, or TLS-level requirements that the DeviceCheck API enforces which could fail silently under certain network conditions? Is this error ever triggered locally (e.g., client library-level issues) or is it always from a failed communication with Apple’s servers? Any technical clarification, documentation, or internal insight into this error code would be greatly appreciated. This would help us significantly narrow down root causes and better support our users

Credential Provider Extension UI Appears Only on Second “Continue” Tap
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!

Title: Sporadical - Permissions Not Cleared After App Uninstallation on iOS18
Title: Sporadical - Permissions Not Cleared After App Uninstallation on iOS18 I install and launch my private MAUI App I ask for example Bluetooth permissions (can be any other permission) I tap Allow button on native settings (or Don't Allow) I unistall app from real phone (we can wait for a while) I install and launch My Private MAUI App I ask for example Bluetooth permissions <- here is an issue. Bluetooth is already granted, so I cannot ask for it again. Occurrence: This issue occurs inconsistently: On iOS 18.5: approximately 5 out of 10 times On iOS 17: approximately 1 out of 50 times Tested using my automated system using Appium latest. After each scenario I unistall app using: "mobile: removeApp" with bundleId

prepareInterfaceToProvideCredential .oneTimeCode case is not called
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.

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 !

Can you use App Attest in Enterprise Builds?
I'm a bit confused about if using App Attest is possible in enterprise builds. It shows up under identifiers in the apple dev portal and I can add it to my provisioning file and entitlements file. But if I go to keys I cannot create a key for it. This page implies it can be used for enterprise builds: After distributing your app through TestFlight, the App Store, or the Apple Developer Enterprise Program, your app ignores the entitlement you set and uses the production environment.

Emerging Issue with macOS Tahoe 26.1 – Full Disk Access (FDA) Behaviour
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. https://developer.apple.com/forums/thread/806187 https://developer.apple.com/forums/thread/806156 https://forum.logik.tv/t/macos-26-1-installation-issue-wait-before-updating/13761 https://www.reddit.com/r/MacOS/comments/1os1ph3/cant_add_anything_to_privacy_security_full_disk/ 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?

Why won't my AutoFill Credential Provider show up in the context menu of a generic textfield?
I noticed, that even though my AutoFill Credential Provider Extension works with Safari for both Passwords and Passkeys, it doesn't work in context menus inside arbitrary textfields, meanwhile the same is true for the Apple Passwords app. This is a great hit to AutoFill productivity, as my extension is unable to fill textfields by just going to the context menu and clicking AutoFill > Passwords.. Is this a feature only available to Apple via private APIs, or is this something I can interface with? I checked and the Passwords app does use some undocumented but non-private entitlements: [Key] com.apple.authentication-services.access-credential-identities [Value] [Bool] true I also checked the responsible executable for some hints (AutoFillPanelService) however found nothing that would lead me to believe this is a public extension point. Another idea I had was trying to use a macOS Service for this, however Services in the "General" category won't show up in any context menu, only in the Application's Main Menu.

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 & 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.

Some items appear in keychain but not passwords
Hi. I enter a password using the security command at the command line. It appears in the keychain access app, but not in the passwords app. I don't understand why. rickhedin@Ricks-MacBook-Pro zalando % security add-generic-password -U -s "birds" -a "cats" -w "dogs" rickhedin@Ricks-MacBook-Pro zalando % rickhedin@Ricks-MacBook-Pro zalando % security find-generic-password -s "birds" -wa "cats" dogs rickhedin@Ricks-MacBook-Pro zalando % I'm told the two apps are two views of the same data, so I guess some filter must be being applied?

Missing privacy manifest
Hi, The email attached states that we need to add GoogleToolboxForMac's missing privacy manifest. I received the attached report after running my app privacy report, however it is different and does not include GoogleToolboxForMac. I'm not sure if we need to add the privacy manifest for GoogleToolboxForMac alone or for both of them. If yes, what should I put in my privacy manifest for GoogleToolboxForMac? IS IT BELOW CODE NEED TO ADD IN PRIVACY MANIFEST OR IS IT BELOW CODE NEED TO ADD IN PRIVACY MANIFEST Please reply ASAP Regards, Viharshitha

Why can’t sandboxed mac app store apps have full disk access available in the system settings for full disk access?
Why can’t sandboxed mac app store apps have full disk access available in the system settings for full disk access? I discovered mac app store apps in release mode cannot access the ai auggie command line program and other command line programs like opengrep on your system. Debug builds fine. I came up with a workaround: Since I have an ssh client built in for connecting to remote servers, why not connect to ssh on the same local machine… Ask the user for their username and password in a popup. To do this, you have to enable remote login on your mac in system settings -> sharing. In addition you must grant full disk access to cli ssh in system settings: add /usr/libexec/sshd-keygen-wrapper It all works, but I don’t see the cli program in mac settings. To remove the cli program you must run a command line program to remove all full disk access support from all apps. No way to just undo ssh. So my question is, even though I got CodeFrog all working for a mac app store release, should I not do it because it’s insecure or too complicated with the system settings? Should I instead sell the app off the store like Panic Nova? Need some advice. I have not implemented in app purchases yet. Should I just have a reality check and sell the app off the store, or try for app store approval? Bummer… Maybe I’m ahead of my time, but perhaps Apple could review the source code for apps requesting full disk access and make sure there’s nothing fraudulent in them. Then, developer tools app store apps could be in the store with the user’s assurance that nothing is happening behind the scenes that is scary. From: https://blog.greenrobot.com/2025/11/10/i-have-a-decision-to-make/ Related post: https://developer.apple.com/forums/thread/806187 I submitted a code level tech support question for this. They directed me here.

FIDO2 USB Monitoring using custom Authorization Plugin
I'm looking to implement USB monitoring for FIDO2 authentication through a custom Authorization Plugin, specifically for the below ones. This plugin applies to the following macOS authorization mechanisms: system.login.console — login window authentication system.login.screensaver — screensaver unlock authentication The goal is to build a GUI AuthPlugin, an authorization plugin that presents a custom window prompting the user to "Insert your FIDO key”. Additionally, the plugin should detect when the FIDO2 device is removed and respond accordingly. Additional Info: We have already developed a custom authorization plugin which is a primary authentication using OTP at login and Lock Screen. We are now extending to include FIDO2 support as a primary. Our custom authorization plugin is designed to replace the default loginwindow:login mechanism with a custom implementation. Question: Is there a reliable approach to achieve the USB monitoring functionality through a custom authorization plugin? Any guidance or pointers on this would be greatly appreciated.

Passwords App is accessing websites from ASCredentialIdentityStore associated with 3rd Party password management app
The Passwords App is accessing websites found in the ASCredentialIdentityStore associated with a 3rd Party password management app (SamuraiSafe). This behaviour appears to be associated with looking up website favicons in order to display in Passwords. However the websites contacted are not stored in the Passwords App/iCloud KeyChain - only the 3rd Party password management app (SamuraiSafe). This is effectively leaking website information stored in the 3rd Party password management app. I first noticed this behaviour on macOS, and it appears to happen every 8 days. Today it was seen on iOS. The behaviour is revealed through the App Privacy Report on iOS (and LittleSnitch on macOS). I would not be surprised to see the Passwords App do this for websites saved in the Passwords App/iCloud KeyChain, however I believe it should not be arbitrarily testing every website found in the ASCredentialIdentityStore as reference to that website url should be entirely under the control of the end user. See attached screenshots from App Privacy Report. Filed bug with Apple: FB16682423

HTTPS Connection Issues Following iOS 26 Beta 6 Update
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. #import "ViewController.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; NSURL *url = [NSURL URLWithString:@"https://i.socdm.com/sdk/js/adg-script-loader-b-stg.js"]; NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:30.0]; [self sendWithRequest:req completionHandler:^(NSData *_Nullable data, NSHTTPURLResponse *_Nonnull response, NSError *_Nullable error) { if (error){ NSLog(@"Error occurred: %@", error.localizedDescription); return; }else{ NSLog(@"Success!

Accessing the key generated by DCAppAttestService
Hi, is it somehow possible to access a key that was generated by the DCAppAttestService generateKey() function? I need to be 100% sure that no actor from within or outside of my app can access the generated key with the DeviceCheck Framework. It would also be helpful to get some official resources to the topic. Thank you in advance, Mike
