Swift iOS iPadOS app for Smartcard Token PIV using CryptoTokenKit
Please excuse my lack of understanding of what are probably fundamental concepts in iOS/iPadOS development but I have searched far and wide for documentation and haven't had much luck so far. I am not sure that what I want to do is even possible with an iPad iPadOS app. Goals: Develop a Swift iPadOS app that can digitally sign a file using a PIV SmartCard/Token (Personal Identity Verification Card): Insert a PIV SmartCard/Token (such as a Yubikey 5Ci) into the lightning port of an iPadOS device iPad (NOT MacOS) Interface with the SmartCard/Token to access the user's PIV certificate/signature and "use it" to sign a file Question 1: How to get the PIV Certificate from SmartCard/Token/Yubikey into iPadOS keychain?   * Do we need to get the PIV certificate into the iOS keychain? Is there another way to interact with a SmartCard directly?   * This should prompt the user for their PIN? Question 2: How to get our Swift app to hook into the event that the SmartCard/Token is inserted into the device and then interface with the user's certificate?   * When is the user prompted to enter their PIN for SmartCard/Token/Yubikey?   * Do we need to use CyrptoTokenKit to interface with a smartcard inserted into the lightning port of an iOS device?

Entitlement values for the Enhanced Security and the Additional Runtime Platform Restrictions
I recently turned on the enhanced security options for my macOS app in Xcode 26.0.1 by adding the Enhanced Security capability in the Signing and Capabilities tab. Then, Xcode adds the following key-value sets (with some other key-values) to my app's entitlements file. <key>com.apple.security.hardened-process.enhanced-security-version</key> <integer>1</integer> <key>com.apple.security.hardened-process.platform-restrictions</key> <integer>2</integer> These values appear following the documentation about the enhanced security feature (Enabling enhanced security for your app) and the app works without any issues. However, when I submitted a new version to the Mac App Store, my submission was rejected, and I received the following message from the App Review team via the App Store Connect. Guideline 2.4.5(i) - Performance Your app incorrectly implements sandboxing, or it contains one or more entitlements with invalid values. Please review the included entitlements and sandboxing documentation and resolve this issue before resubmitting a new binary. Entitlement "com.apple.security.hardened-process.enhanced-security-version" value must be boolean and true. Entitlement "com.apple.security.hardened-process.platform-restrictions" value must be boolean and true. When I changed those values directly in the entitlements file based on this message, the app appears to still work. However, these settings are against the description in the documentation I mentioned above and against the settings Xcode inserted after changing the GUI setting view. So, my question is, which settings are actually correct to enable the Enhanced Security and the Additional Runtime Platform Restrictions?

Cannot configure Sign in with Apple – Save fails with 501 Not Implemented
Hello, I am unable to configure Sign in with Apple on my developer account. Whenever I try to: Enable/disable the Sign in with Apple capability in my App ID, or Configure a Service ID for web authentication, the portal does not save my changes. In the browser developer console, I consistently see this error: Request URL: https://developer.apple.com/services-account/v1/bundleIds/XXXXXXXX Request Method: PATCH Status Code: 501 Not Implemented This happens across all browsers (Safari, Chrome, Incognito) and even after clearing cache. It affects my entire account, not just one App ID. I have already tried: Creating a new Service ID → still fails. Creating a new App ID → still fails. Re-enabling the capability → save does not work. Different browsers and devices → same result. Has anyone else experienced this issue, and is there a known fix? Or is this something that Apple Developer Support needs to resolve at the account level?

500 error on validate_device_token endpoint since around March 4
Since around March 4, 2025 off and on, we've been receiving 500 errors back from the validate_device_token endpoint on development and production. Today (March 6) we are constantly getting 500 error back. https://api.development.devicecheck.apple.com/v1/validate_device_token This was working previously before then. No change has happened on our end since then. This is a critical piece for our infrastructure. Thanks in advance. -Matt

Empty passkey list in ASCredentialIdentityStore
I have been able to save and remove ASPasskeyCredentialIdentities in the ASCredentialIdentityStore. But after saving a ASPasskeyCredentialIdentity, when I retrieve the current identities stored, it always returns an empty list. I check to make sure the store is enabled. I am using this method which is available starting with iOS 17.4: extension ASCredentialIdentityStore { public func credentialIdentities(forService serviceIdentifier: ASCredentialServiceIdentifier? = nil, credentialIdentityTypes: ASCredentialIdentityStore.IdentityTypes = []) async -&gt; [any ASCredentialIdentity] } I have called it like this: store.credentialIdentities(forService: nil, credentialIdentityTypes: .passkey) And this: store.credentialIdentities() Has anyone got this to work?

Invalid web redirect url
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, I have the exact same problem. The newly registered URL is not working after 5 days, while the URL I have deleted from the configuration is still operational. In addition to the above problem, I also get a response of 'invalid_client' when I newly register a service in configuration. Please check it out as it needs to be resolved quickly.

Auth Plugin Timeout Issue During Screen Unlock
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!

Sign-Up Not Complete error in integration of sign in with Apple
I hope this problem could be solved, also in case any other one strugling the same issue could be helpful. We are developing an iOS App which use "sign in with Apple" feature. We found we can not login with this feature, the "sign in with Apple" dialog box always flash an error info "Sign-Up Not Complete". We have double checked configuration of Bundle ID, and xcode capabilities, info.plist, entitlements, etc. We have even changed the developer team, using other bundle ID and demo code to testify this, also got failure of "Sign-Up Not Complete" error. We did even just use Apple official demo code (https://developer.apple.com/documentation/AuthenticationServices/implementing-user-authentication-with-sign-in-with-apple), also got the same failure. Interestingly, we found that using some old Bundle IDs which created before (even we did not use it for App yet), we could get "sign in with Apple" success logged in. Therefore we now can not include "sign in with Apple" feature in our App today, and this is the key feature in our App. Please help. Since there is very little information we could collect, I just put the debug error here: Authorization failed: Error Domain=AKAuthenticationError Code=-7003 "(null)" UserInfo={AKClientBundleID=com.nethawk.flutter.battlebuddy} LaunchServices: store (null) or url (null) was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=72, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} Attempt to map database failed: permission was denied.

Binary executable requires Accessibility Permissions in Tahoe
I have a binary executable which needs to be given Accessibility Permissions so it can inject keypresses and mouse moves. This was always possible up to macOS 15 - when the first keypress arrived the Accessibility Permissions window would open and allow me to add the executable. However this no longer works in macOS 26: the window still opens, I navigate to the executable file and select it but it doesn't appear in the list. No error message appears. I'm guessing that this may be due to some tightening of security in Tahoe but I need to figure out what to change with my executable to allow it to work.

Enhanced Security Capability < iOS 26
Hi, After enabling the new Enhanced Security capability in Xcode 26, I’m seeing install failures on devices running < iOS 26. Deployment target: iOS 15.0 Capability: Enhanced Security (added via Signing & Capabilities tab) Building to iOS 18 device error - Unable to Install ...Please ensure sure that your app is signed by a valid provisioning profile. It works fine on iOS 26 devices. I’d like to confirm Apple’s intent here: Is this capability formally supported only on iOS 26 and later, and therefore incompatible with earlier OS versions? Or should older systems ignore the entitlement, meaning this behavior might be a bug?

App Attest Suddenly Failing in Production — Error 4 (serverUnavailable)
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!

Issue: Plain Executables Do Not Appear Under “Screen & System Audio Recording” on macOS 26.1 (Tahoe)
Summary I am investigating a change in macOS 26.1 (Tahoe) where plain (non-bundled) executables that request screen recording access no longer appear under: System Settings → Privacy & Security → Screen & System Audio Recording This behavior differs from macOS Sequoia, where these executables did appear in the list and could be managed through the UI. Tahoe still prompts for permission and still allows the executable to capture the screen once permission is granted, but the executable never shows up in the UI list. This breaks user expectations and removes UI-based permission management. To confirm the behavior, I created a small reproduction project with both: a plain executable, and an identical executable packaged inside an .app bundle. Only the bundled version appears in System Settings. Observed Behaviour 1. Plain Executable (from my reproduction project) When running a plain executable that captures the screen: macOS displays the normal screen-recording permission prompt. Before granting permission: screenshots show only the desktop background. After granting permission: screenshots capture the full display. The executable does not appear under “Screen & System Audio Recording”. Even when permission is granted manually (e.g., dragging the executable into the pane), the executable still does not appear, which prevents the user from modifying or revoking the permission through the UI. If the executable is launched from inside another app (e.g., VS Code, Terminal), the parent app appears in the list instead, not the executable itself. 2. Bundled App Version (from the reproduction project) I packaged the same code into a simple .app bundle (ScreenCaptureApp.app). When running the app: The same permission prompt appears. Pre-permission screenshots show the desktop background. Post-permission screenshots capture the full display. The app does appear under “Screen & System Audio Recording”. This bundle uses the same underlying executable — the only difference is packaging. Hypothesis macOS 26.1 (Tahoe) appears to require app bundles for an item to be shown in the Screen Recording privacy UI. Plain executables: still request and receive permission, still function correctly after permission is granted, but do not appear in the System Settings list. This may be an intentional change, undocumented behavior, or a regression. Reproduction Project The reproduction project includes: screen_capture.go A simple Go program that captures screenshots in a loop. screen_capture_executable Plain executable built from the Go source. ScreenCaptureApp.app/ App bundle containing the same executable. build.sh Builds both the plain executable and the app bundle. Permission reset and TCC testing scripts. The project demonstrates the behavior consistently. Steps to Reproduce Plain Executable Build: ./build.sh Reset screen capture permissions: sudo tccutil reset ScreenCapture Run: ./screen_capture_executable Before granting: screenshots show desktop only. Grant permission when prompted. After granting: full screenshots. Executable does not appear in “Screen & System Audio Recording”. Bundled App Build (if not already built): ./build.sh Reset permissions (optional): sudo tccutil reset ScreenCapture Run: open ScreenCaptureApp.app Before granting: screenshots show desktop. After granting: full screenshots. App bundle appears in the System Settings list. Additional Check I also tested launching the plain executable as a child process of another executable, similar to how some software architectures work. Result: Permission prompt appears Permission can be granted Executable still does not appear in the UI, even though TCC tracks it internally → consistent with the plain-executable behaviour. This reinforces that only app bundles are listed. Questions for Apple Is the removal of plain executables from “Screen & System Audio Recording” an intentional change in macOS Tahoe? If so, does Apple now require all screen-recording capable binaries to be packaged as .app bundles for the UI to display them? Is there a supported method for making a plain executable (launched by a parent process) appear in the list? If this is not intentional, what is the recommended path for reporting this as a regression? Files Unfortunately, I have discovered the zip file that contains my reproduction project can't be directly uploaded here. Here is a Google Drive link instead: https://drive.google.com/file/d/1sXsr3Q0g6_UzlOIL54P5wbS7yBkpMJ7A/view?usp=sharing Thank you for taking the time to review this. Any insight into whether this change is intentional or a regression would be very helpful.

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!

Full disk access for CLI app
It seems it is not possible to give a CLI app (non .app bundle) full disk access in macOS 26.1. This seems like a bug and if not that is a breaking change. Anybody seeing the same problem? Our application needs full disk access for a service running as a LaunchDaemon. The binary is located in a /Library subfolder.

ASWebAuthenticationSession Async/Await API
Is there any particular reason why ASWebAuthenticationSession doesn't have support for async/await? (example below) do { let callbackURL = try await webAuthSession.start() } catch { // handle error } I'm curious if this style of integration doesn't exist for architectural reasons? Or is the legacy completion handler style preserved in order to prevent existing integrations from breaking?
