API to query for Guest User Mode on VisionOS?
Hi! Is there currently any public API for product engineers to query for Guest User mode?^1 Is there an API product engineers can query at runtime to determine if their app is running as a Guest User on visionOS? I am not able to find any API that directly returns this information. But it does look some APIs can indirectly return this. HealthKit can condition some of its response values on Guest User mode.^2 It is possible that querying through HealthKit might be a workaround. But it would require asking for health data even in Vision Apps that do not really need health data. I would still be looking for something like a direct Guest User API if that was available. Thanks!

TKTokenDriverConfiguration becomes permanently unusable after ctkd process restart
Background We're building a macOS application that acts as a CryptoTokenKit software token. The architecture follows the documented pattern: a container app (a long-running agent process) manages token registration and identity updates via TKTokenDriverConfiguration, and a separate appex extension process handles the actual signing operations for client sessions. What we're doing At agent startup, the container app calls [TKTokenDriverConfiguration driverConfigurations] to obtain our token driver, then registers a token instance ID: NSDictionary<TKTokenDriverClassID, TKTokenDriverConfiguration *> *driverConfigurations = [TKTokenDriverConfiguration driverConfigurations]; TKTokenDriverConfiguration driver = / first value from driverConfigurations */; [driver addTokenConfigurationForTokenInstanceID:@"setoken"]; When the agent renews a certificate, it pushes updated TKTokenKeychainItem objects to ctkd by setting keychainItems on the TKTokenConfiguration: TKTokenConfiguration *tokenCfg = driver.tokenConfigurations[@"setoken"]; tokenCfg.keychainItems = updatedItems; This works correctly during normal operation. The failure When ctkd is restarted (e.g., killall ctkd, or the system restarts the daemon), all subsequent calls through the existing TKTokenDriverConfiguration reference silently fail. Specifically: [TKTokenDriverConfiguration driverConfigurations] returns the same stale object - it does not establish a new connection to the newly-started ctkd process. There is no error, no exception, and no indication the returned object is invalid. driver.tokenConfigurations[@"setoken"] still returns a non-nil value reflecting the pre-restart state - so any nil check intended to detect "token not registered with ctkd" does not fire. [driver addTokenConfigurationForTokenInstanceID:@"setoken"] appears to succeed (no error) but the token is not actually registered with the new ctkd instance. Setting tokenCfg.keychainItems = updatedItems appears to succeed but the new ctkd instance has no knowledge of the update. The only reliable recovery we've found is restarting the container app process itself, at which point [TKTokenDriverConfiguration driverConfigurations] returns a fresh object connected to the new ctkd instance. What we've investigated There is no public API on TKTokenDriverConfiguration to invalidate or refresh the internal XPC connection to ctkd TKTokenWatcher can observe token insertions/removals, but we found no documented way to use it to detect a ctkd process restart specifically The NSXPCConnection invalidation handler pattern is not accessible through the TKTokenDriverConfiguration abstraction Moving credential management into the appex extension. Since the appex extension is recreated when the ctkd process restarts, we are able to update keychainItems from the extension. However, this comes with it's own set of problems: the extension is ephemeral and using the keychain APIs directly from the extension is not well documented and does not appear to be a supported pattern. Questions Is there a supported API to detect that ctkd has restarted and that the existing TKTokenDriverConfiguration reference is no longer valid? Is there a supported way to obtain a fresh TKTokenDriverConfiguration without restarting the container app? Should the container app be re-architected to avoid holding long-lived TKTokenDriverConfiguration references?

App Attest assertions rejected as invalid by downstream validator on iOS 26.x — fleet-wide, pristine first-install devices
Symptom Production iOS app (TestFlight) using App Attest. Devices generate assertions via DCAppAttestService (through Firebase App Check, which forwards to Apple's validation infrastructure). The fleet was attesting cleanly at ~100% verified for the first ~7 days post-first-install per device — then collapsed to ~0% verified once the initial token's natural TTL expired and devices were forced to re-attest. Has stayed at ~0% for 3+ days. Affects all 4 physical TestFlight devices; not reproducing on simulators (which is expected — App Attest unavailable there). The downstream validator's metric specifically categorizes these as "invalid" — meaning a token reached it and was rejected as cryptographically invalid — not as "no token sent" / "unrecognized origin" / "outdated SDK." Environment iOS 26.x (26.3.1 confirmed on multiple devices). Team ID T68SS8UY5J, bundle com.calimento.app, App ID has App Attest capability checked. Entitlements signed into binary: com.apple.developer.devicecheck.appattest-environment = production. Xcode would refuse this embed if the App ID lost the capability — so capability state is verifiably intact. Provisioning profile UUID byte-identical between the last verified-traffic build and the first invalid-traffic build (confirmed via Xcode build logs). Same code-signing identity hash across both builds. TestFlight builds approved by Apple Beta Review. What's been ruled out Provisioning / signing / certificate drift (UUID and cert hash unchanged across builds). App ID capability revocation (entitlement embed succeeded). Firebase iOS app config drift (GoogleService-Info.plist byte-identical across vault, local working tree, and Firebase Console download). Token attachment / SDK init race (0% of requests in the "no token" or "outdated client" buckets). Pod / dependency drift (package-lock byte-identical between verified and failing builds). The integration was producing valid assertions for ~7 days post-install per device — code-side bugs would have manifested from day one, not synchronized to the TTL boundary. Questions Are there known iOS 26.x server-side issues with App Attest assertion validation that would cause hardware-generated assertions to be rejected as cryptographically invalid? Is there a documented or undocumented abuse-mitigation behavior that downgrades or invalidates assertions for an App ID under specific conditions — e.g., after a volume threshold within a window, or after a fingerprint anomaly? Looking specifically at whether high attestation churn during development can leave an App ID's attestation state in a degraded mode. Is there any way to inspect Apple's reason for rejecting a specific assertion — through a developer tool, console log, or feedback channel? The downstream validator only surfaces"invalid"; it doesn't report Apple's underlying rejection reason. Recovery semantics: if a device's keyId ends up internally blocklisted, does it age out, or is the device permanently unable to produce valid assertions for that App ID? appattest-environment = production validation flow: any way the production environment validator could differ from development in a way that produces this signature? Why I'm filing here rather than only with the SDK maintainer: The SDK is reliably attaching tokens (0% in the "no token" bucket). Origin is being recognized (0% in the "unknown origin" bucket). The rejection is happening at signature validation — which is downstream of any client-SDK behavior. Cross-filed with the React Native Firebase maintainers at [https://github.com/invertase/react-native-firebase/issues/9008]; if the root cause turns out to be on the wrapper's side, that thread will be closed. Happy to provide raw build logs, validator metric exports, or a build for a test device on Apple's side privately.

way to attest that a Secure Enclave key is hardware-bound on macOS
We generate Secure Enclave keys via SecKeyCreateRandomKey with kSecAttrTokenIDSecureEnclave on macOS. We need to prove to a remote server that the key is genuinely hardware-bound, not a software key claiming to be one. Is there any API on macOS for an app to obtain an Apple-signed certificate or attestation statement for such a Secure Enclave key, similar to how ASAuthorizationProviderExtensionLoginManager.attestKey() works within Platform SSO but available to general apps? Or other possible workaround for this? Thank you!

Requesting guidance on Endpoint Security entitlement (com.apple.developer.endpoint-security.client) for per-process network connection telemetry on managed macOS
Hi Apple Developer Forums, We are developing a managed macOS security/monitoring agent for enterprise customers (deployed only to MDM-managed endpoints). Our goal is to collect per-process network connection metadata (e.g., which process initiated a TCP connection, destination IP/port, timestamps). We are not intercepting or collecting network payload/content—only connection metadata for security telemetry/compliance. We previously explored options like: sysctl PCB lists (e.g., net.inet.tcp.pcblist_n) / kernel structs (not stable ABI; appears private/fragile) Aggregate TCP stats (sysctl net.inet.tcp.stats) which are public but system-wide only proc_pidinfo() / PROC_PIDFDSOCKETINFO for per-PID socket snapshots (polling-based; limited / not event-driven) It seems the supported, event-based approach for per-process connection visibility is EndpointSecurity.framework, but it requires the entitlement: com.apple.developer.endpoint-security.client Questions: Is EndpointSecurity.framework the recommended/supported approach for per-process TCP connection events on macOS for a managed enterprise security agent? What is the correct process to request approval for the Endpoint Security client entitlement under an Apple Developer Program team? (We were directed to post here.) Which Endpoint Security event types are appropriate for capturing connect/accept/close style network events per-process, strictly for metadata telemetry? Are there any platform/privacy constraints or best practices Apple expects us to follow for this use case (MDM-managed enterprise deployments)? We can provide additional details (distribution method, signing, MDM deployment model, privacy disclosures) if needed. Thanks!

Contacts permission not requested on production build (iPhone 16/17 Pro Max)
I’m encountering an issue where my app does not show the Contacts permission prompt in the production environment. This has been observed on iPhone 16 Pro Max and iPhone 17 Pro Max devices, while other iPhone models appear to behave correctly. The behavior is consistent across Xcode builds, TestFlight, and the App Store version when using the production bundle identifier. Instead of returning .notDetermined, the app receives the device’s previous Contacts authorization status, so the system permission prompt is never shown. Expected behavior On first launch after install, the app should prompt the user for Contacts access. Actual behavior (Production build) The app does not prompt for Contacts permission and instead appears to reuse the previous permission state: If the user previously had no access → after uninstall/reinstall, still no access (no prompt shown) If the user previously had limited access → after reinstall, access becomes empty (0 contacts), still no prompt If the user previously had full access → after reinstall, still has full access without being prompted Additional observations This issue only occurs in Production Staging and Dev builds (TestFlight + Xcode) behave correctly and prompt for permission If I set my Dev build to use the same bundle identifier as Production, the issue reproduces (no permission prompt) Current workaround The only way for users to change Contacts access is via the Settings app. The permission prompt is never shown in-app. Has anyone encountered this behavior before, or is there something specific to production builds (or bundle identifiers) that could cause the system to skip the permission prompt?

Platform SSO in ADE and login grant type
We are implementing Platform SSO with Secure Enclave–based authentication. In a standard (post-enrollment) flow, everything behaves as expected: Authentication uses urn:ietf:params:oauth:grant-type:jwt-bearer The Secure Enclave–backed credential is used correctly However, when using Automated Device Enrollment (ADE) with Simplified Setup, we observe different behavior: After device registration, Platform SSO triggers a login request to our IdP That request uses grant_type=password Instead of the expected urn:ietf:params:oauth:grant-type:jwt-bearer This occurs even though: The configuration specifies Secure Enclave as the authentication method The same configuration works as expected outside ADE Questions: Is this password grant during ADE / Simplified Setup an expected bootstrap flow? Is there any official documentation describing this? This behavior is currently undocumented, and clarification would help ensure correct IdP implementation.

ASWebAuthentication Issue with using HTTPS callback domain
I'm following up from an old existing post per the recommendation by DTS Engineer I'm referencing that comment specifically because i'm only able to reproduce this issue when using a device through browserstack. (a service that allows remote access to physical ios devices for testing, etc) I haven't been able to reproduce the issue on my physical device. When attempting to launch an ASWebAuthenticationSession using callback: .https(host: path:), The session immediately fails (before even presenting the web modal) with the error: Error Domain=com.apple.AuthenticationServices.WebAuthenticationSession Code=1 NSLocalizedFailureReason=Application with identifier com.builderTREND.btMobileAppAdHoc is not associated with domain test.buildertrend.net. Using HTTPS callbacks requires Associated Domains using the webcredentials service type for test.buildertrend.net. Which doesn't make sense, since our AASA file does specify that url and has the app ID listed in webcredentials Our app's entitlements file also contains webcredentials:*.buildertrend.net So it seems like everything is set up properly, but this issue is persistent.

Clarification on when `ASAuthorizationProviderExtensionAuthorizationRequest.isCallerManaged` is `true`
Hi, I’m working with an SSO extension (ASAuthorizationProviderExtension) and am looking for clarification on how Apple determines whether the calling app is considered managed for ASAuthorizationProviderExtensionAuthorizationRequest.isCallerManaged. In my test, the authorization request is triggered from an app that is managed by our organization. We are using Jamf. However, in the SSO extension, I see the following caller metadata isCallerManaged=false I’d like to understand what conditions must be met for isCallerManaged to return true. Thanks.

macOS Sonoma Lock Screen with SFAutorizationPluginView is not hiding the macOS desktop
On Sonoma beta 7, if system.login.screensaver is updated to use “authenticate-session-owner-or-admin”, and then Lock Screen is not hiding the macOS Desktop. Step1. Update system.login.screensaver authorizationdb rule to use “authenticate-session-owner-or-admin”( to get old SFAutorizationPluginView at Lock Screen ). Step 2. Once the rule is in place after logout and login, now click on Apple icon and select “Lock Screen”. Even after selecting Lock Screen, complete macOS Desktop is visible with no control for the user to unlock the screen. To gain access we have to restart the MAC.

Can CLI apps not use SecItemAdd?
tl;dr: The title and/or can I even add a keychain entitlement to a cli app? I'm trying to store a generated private key and certificate properly in a CLI app. The call to SecItemAdd always results in an error with message A required entitlement isn't present. I assume this is errSecMissingEntitlement, and its docs say it happens "when you specify an access group to which your app doesn’t belong". But I'm not even specifying one. Here's a small excerpt (I know it's not a MVCE but the question is pretty general anyway): func storeCert(_ cert: Data) throws { let addQuery = [ kSecClass: kSecClassCertificate, kSecValueRef: cert, kSecAttrLabel: CERT_USER_LABEL, kSecAttrApplicationLabel: CERT_APP_LABEL ] as [String: Any] let status = SecItemAdd(addQuery as CFDictionary, nil) guard status == errSecSuccess else { let msg = SecCopyErrorMessageString(status, nil) as String? ?? "" throw MyErr.generic(message: "Unable to store cert: \(msg)") } } I can't add the keychain entitlement to my CLI target, it doesn't show as an option in the add capability window. Disclaimer: I'm quite new to macOS / Apple development, so if there's something obvious I'm missing, my bad.

Custom right using builtin:authenticate on macOS
When implementing a custom right in macOS authorizationdb, the mechanism array element builtin:authenticate is displaying the message 'Enter the name and password of a user in the "(null)" group to allow this.' on the macOS credential prompt UI popup. I am trying to find a fix to avoid the reference to null group in the message label that is displayed just above the username and password input fields. The current plist uses class as the key and value as the evaluate-mechanisms. The mechanisms array includes mechanism array with elements "builtin:login-begin", "mycustombundle:mycustompreaction", "builtin:authenticate", "mycustombundle:mycustommechanism". I have tried specifying group in the plist, have tried setting hint in the MechanismInvoke for group, username, security, authority, prompt, reason among several other hints into the context duing the execution of mycustombundle:mycustompreaction, but none seem to fix the "(null)" in the message label. Any help is greately appreciated. There is not much of any documentation for developers implementing custom authorization in macOS.

Disable “Save Password” Prompt While Keeping AutoFill Enabled
Hi Apple Developer Community, Quick question — is there currently a way to disable the “Save Password” prompt in iOS while keeping AutoFill enabled? From what I can see, the only available setting under Settings → Passwords → Password Options controls AutoFill as a whole, with no option to turn off just the save prompt. I’m using a third-party password manager and would prefer to keep AutoFill but avoid the repeated prompts to save credentials. Has anyone found a workaround for this, or is this simply not configurable at the moment? Thanks!

How to reset user preference for crypto token kit access
When an app is trying to access identities put in the keychain by cryptotokenkit extension, the user gets asked a permission pop-up which reads 'Token Access Request" would like access a token provided by: " with 2 options 'Don't allow' and 'OK' I accidently clicked "Don't allow" and now can't access identities put in crypto token kit. How can I reset the preference?

ATT and Google AdMob
Hi, I created an app and want to use Google Admob to show ads. I am a little bit confused how exactly tracking, more specifically, the ATT-framework and Google Admob relate to each other. The current work flow is: ATT-permission given -> show google ad mob consent form However, I am confused what I should do if the ATT permission is denied. Can I still show the consent form of google admobs or is that forbidden? If so what do I need to then? Thank you!

PCC VRE: 403 Forbidden when downloading SW Release 41303
Is anyone else seeing 403 errors for PCC VRE when trying to pull assets for Release 41303? My pccvre audit of the Transparency Log passes (valid root digests for 41385), but the download fails consistently on specific CDN URLs: Failed to download SW release asset... response: 403 I’ve verified csrutil allow-research-guests is active and the license is accepted. Release 41385 seems fine, but 41303 is a brick wall. Is this a known pull-back or a CDN permissions sync issue?

AID A000000308000010000100 seems mandatory to communicate with any smart card through TKSmartCardSlotNFCSession
I am using the CryptoTokenKit API in order to communicate with smart cards through NFC, with TKSmartCardSlotNFCSession. I call the createNFCSlotWithMessage method from TKSmartCardSlotManager, which displays successfuly the NFC dialog. However, when I put any smart card next to the phone, the NFC dialog shuts down instantly. I notice the following log in the system console: -[_NFReaderSession(Entitlement) validateAID:allowsPrefixMatch:]:317 Non-permissible identifier: A000000308000010000100 When I add the A000000308000010000100 AID mentioned in the error message to the Info.plist of my application, the NFC dialog does not shut down anymore and I am able to communicate with the smart card (using TKSmartCard). This behavior has been reproduced on an iPhone 16e, iOS 26.4. This AID does not correspond to anything in the smart card. It seems to be related to PIV, but this behavior also occurs with cards that are not PIV (PKCS#15...). Also, with an implementation using CoreNFC API instead of CryptoTokenKit API, this AID is not needed to be able to communicate with the card, so it seems CryptoTokenKit-specific. I did not find anything related to this in the documentation, have I missed something here ? Is this a special AID that is required all the time to work with NFC through CryptoTokenKit ?

Expected behavior On first launch after install, the app should prompt the user for Contacts access. Actual behavior (Production build) The app does not prompt for Contacts permission and instead appears to reuse the previous permission state: If the user previously had no access → after uninstall/reinstall, still no access (no prompt shown) If the user previously had limited access → after reinstall, access becomes empty (0 contacts), still no prompt If the user previously had full access → after reinstall, still has full access without being prompted Additional observations This issue only occurs in Production Staging and Dev builds (TestFlight + Xcode) behave correctly and prompt for permission If I set my Dev build to use the same bundle identifier as Production, the issue reproduces (no permission prompt) Current workaround The only way for users to change Contacts access is via the Settings app. The permission prompt is never shown in-app. Has anyone encountered this behavior before, or is there something specific to production builds (or bundle identifiers) that could cause the system to skip the permission prompt?

Platform SSO in ADE and login grant type
We are implementing Platform SSO with Secure Enclave–based authentication. In a standard (post-enrollment) flow, everything behaves as expected: Authentication uses urn:ietf:params:oauth:grant-type:jwt-bearer The Secure Enclave–backed credential is used correctly However, when using Automated Device Enrollment (ADE) with Simplified Setup, we observe different behavior: After device registration, Platform SSO triggers a login request to our IdP That request uses grant_type=password Instead of the expected urn:ietf:params:oauth:grant-type:jwt-bearer This occurs even though: The configuration specifies Secure Enclave as the authentication method The same configuration works as expected outside ADE Questions: Is this password grant during ADE / Simplified Setup an expected bootstrap flow? Is there any official documentation describing this? This behavior is currently undocumented, and clarification would help ensure correct IdP implementation.

ASWebAuthentication Issue with using HTTPS callback domain
I'm following up from an old existing post per the recommendation by DTS Engineer I'm referencing that comment specifically because i'm only able to reproduce this issue when using a device through browserstack. (a service that allows remote access to physical ios devices for testing, etc) I haven't been able to reproduce the issue on my physical device. When attempting to launch an ASWebAuthenticationSession using callback: .https(host: path:), The session immediately fails (before even presenting the web modal) with the error: Error Domain=com.apple.AuthenticationServices.WebAuthenticationSession Code=1 NSLocalizedFailureReason=Application with identifier com.builderTREND.btMobileAppAdHoc is not associated with domain test.buildertrend.net. Using HTTPS callbacks requires Associated Domains using the webcredentials service type for test.buildertrend.net. Which doesn't make sense, since our AASA file does specify that url and has the app ID listed in webcredentials Our app's entitlements file also contains webcredentials:*.buildertrend.net So it seems like everything is set up properly, but this issue is persistent.

Clarification on when `ASAuthorizationProviderExtensionAuthorizationRequest.isCallerManaged` is `true`
Hi, I’m working with an SSO extension (ASAuthorizationProviderExtension) and am looking for clarification on how Apple determines whether the calling app is considered managed for ASAuthorizationProviderExtensionAuthorizationRequest.isCallerManaged. In my test, the authorization request is triggered from an app that is managed by our organization. We are using Jamf. However, in the SSO extension, I see the following caller metadata isCallerManaged=false I’d like to understand what conditions must be met for isCallerManaged to return true. Thanks.

macOS Sonoma Lock Screen with SFAutorizationPluginView is not hiding the macOS desktop
On Sonoma beta 7, if system.login.screensaver is updated to use “authenticate-session-owner-or-admin”, and then Lock Screen is not hiding the macOS Desktop. Step1. Update system.login.screensaver authorizationdb rule to use “authenticate-session-owner-or-admin”( to get old SFAutorizationPluginView at Lock Screen ). Step 2. Once the rule is in place after logout and login, now click on Apple icon and select “Lock Screen”. Even after selecting Lock Screen, complete macOS Desktop is visible with no control for the user to unlock the screen. To gain access we have to restart the MAC.

Can CLI apps not use SecItemAdd?
tl;dr: The title and/or can I even add a keychain entitlement to a cli app? I'm trying to store a generated private key and certificate properly in a CLI app. The call to SecItemAdd always results in an error with message A required entitlement isn't present. I assume this is errSecMissingEntitlement, and its docs say it happens "when you specify an access group to which your app doesn’t belong". But I'm not even specifying one. Here's a small excerpt (I know it's not a MVCE but the question is pretty general anyway): func storeCert(_ cert: Data) throws { let addQuery = [ kSecClass: kSecClassCertificate, kSecValueRef: cert, kSecAttrLabel: CERT_USER_LABEL, kSecAttrApplicationLabel: CERT_APP_LABEL ] as [String: Any] let status = SecItemAdd(addQuery as CFDictionary, nil) guard status == errSecSuccess else { let msg = SecCopyErrorMessageString(status, nil) as String? ?? "" throw MyErr.generic(message: "Unable to store cert: \(msg)") } } I can't add the keychain entitlement to my CLI target, it doesn't show as an option in the add capability window. Disclaimer: I'm quite new to macOS / Apple development, so if there's something obvious I'm missing, my bad.

Custom right using builtin:authenticate on macOS
When implementing a custom right in macOS authorizationdb, the mechanism array element builtin:authenticate is displaying the message 'Enter the name and password of a user in the "(null)" group to allow this.' on the macOS credential prompt UI popup. I am trying to find a fix to avoid the reference to null group in the message label that is displayed just above the username and password input fields. The current plist uses class as the key and value as the evaluate-mechanisms. The mechanisms array includes mechanism array with elements "builtin:login-begin", "mycustombundle:mycustompreaction", "builtin:authenticate", "mycustombundle:mycustommechanism". I have tried specifying group in the plist, have tried setting hint in the MechanismInvoke for group, username, security, authority, prompt, reason among several other hints into the context duing the execution of mycustombundle:mycustompreaction, but none seem to fix the "(null)" in the message label. Any help is greately appreciated. There is not much of any documentation for developers implementing custom authorization in macOS.

Disable “Save Password” Prompt While Keeping AutoFill Enabled
Hi Apple Developer Community, Quick question — is there currently a way to disable the “Save Password” prompt in iOS while keeping AutoFill enabled? From what I can see, the only available setting under Settings → Passwords → Password Options controls AutoFill as a whole, with no option to turn off just the save prompt. I’m using a third-party password manager and would prefer to keep AutoFill but avoid the repeated prompts to save credentials. Has anyone found a workaround for this, or is this simply not configurable at the moment? Thanks!

FIPS140-3 Compliance Intel
Apple's submission for FIPS140-3 (https://support.apple.com/guide/certifications/macos-security-certifications-apc35eb3dc4fa/web) has no mention of review for Intel or Intel T2 in FIPS Compliance on Tahoe. Is there any effort for this or will there be any effort? Has there any been any word that Intel as an architecture is completely out of the picture for FIPS140-3?

ATT and Google AdMob
Hi, I created an app and want to use Google Admob to show ads. I am a little bit confused how exactly tracking, more specifically, the ATT-framework and Google Admob relate to each other. The current work flow is: ATT-permission given -> show google ad mob consent form However, I am confused what I should do if the ATT permission is denied. Can I still show the consent form of google admobs or is that forbidden? If so what do I need to then? Thank you!

PCC VRE: 403 Forbidden when downloading SW Release 41303
Is anyone else seeing 403 errors for PCC VRE when trying to pull assets for Release 41303? My pccvre audit of the Transparency Log passes (valid root digests for 41385), but the download fails consistently on specific CDN URLs: Failed to download SW release asset... response: 403 I’ve verified csrutil allow-research-guests is active and the license is accepted. Release 41385 seems fine, but 41303 is a brick wall. Is this a known pull-back or a CDN permissions sync issue?

AID A000000308000010000100 seems mandatory to communicate with any smart card through TKSmartCardSlotNFCSession
I am using the CryptoTokenKit API in order to communicate with smart cards through NFC, with TKSmartCardSlotNFCSession. I call the createNFCSlotWithMessage method from TKSmartCardSlotManager, which displays successfuly the NFC dialog. However, when I put any smart card next to the phone, the NFC dialog shuts down instantly. I notice the following log in the system console: -[_NFReaderSession(Entitlement) validateAID:allowsPrefixMatch:]:317 Non-permissible identifier: A000000308000010000100 When I add the A000000308000010000100 AID mentioned in the error message to the Info.plist of my application, the NFC dialog does not shut down anymore and I am able to communicate with the smart card (using TKSmartCard). This behavior has been reproduced on an iPhone 16e, iOS 26.4. This AID does not correspond to anything in the smart card. It seems to be related to PIV, but this behavior also occurs with cards that are not PIV (PKCS#15...). Also, with an implementation using CoreNFC API instead of CryptoTokenKit API, this AID is not needed to be able to communicate with the card, so it seems CryptoTokenKit-specific. I did not find anything related to this in the documentation, have I missed something here ? Is this a special AID that is required all the time to work with NFC through CryptoTokenKit ?
