Hi Apple Developer： I'm having some problems with iOS15 WebAuthn. Can't found parameter for excludeList at the time of registration.Can‘t found parameter for allowList at the time of authentication. When I use an external authenticator, the registration succeeds, but the authentication prompts that no credentials are available. Related to the interface： ASAuthorizationSecurityKeyPublicKeyCredentialProvider； ASAuthorizationPlatformPublicKeyCredentialRegistration； Best regards；

I have many questions about iOS passkey. I'm using my app extension to implement something similar to an iCloud passkey authenticator. I securely store my self-generated keys in the Secure Enclave (SE). I'd like to know how to make the extension execute the prepareInterfaceToProvideCredentialForRequest method instead of provideCredentialWithoutUserInteractionForIdentity. I need to display a UI to obtain my key. Please provide assistance. Thank you.

Hello, when I attempted to use the passkey, the method - (void)prepareCredentialListForServiceIdentifiers:(NSArray<ASCredentialServiceIdentifier *> *)serviceIdentifiers requestParameters:(ASPasskeyCredentialRequestParameters *)requestParameters API_AVAILABLE(ios(17.0), macos(14.0)) API_UNAVAILABLE(watchos, tvos); didn't execute. Are there any specific prerequisites for this method to run? I would appreciate your assistance. Thank you.

Hi Apple Developers, I'm having a problem with evaluatedPolicyDomainState: on the same device, its value keeps changing and then switching back to the original. My current iOS version is 26.1. I upgraded my iOS from version 18.6.2 to 26.1. What could be the potential reasons for this issue? { NSError *error; BOOL success = YES; char *eds = nil; int edslen = 0; LAContext *context = [[LAContext alloc] init]; // test if we can evaluate the policy, this test will tell us if Touch ID is available and enrolled // success = [context canEvaluatePolicy: LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&error]; if (SystemVersion > 9.3) { // test if we can evaluate the policy, this test will tell us if Touch ID is available and enrolled success = [context canEvaluatePolicy: LAPolicyDeviceOwnerAuthentication error:&error]; } else{ // test if we can evaluate the policy, this test will tell us if Touch ID is available and enrolled success = [context canEvaluatePolicy: LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&error]; } if (success) { if (@available(iOS 18.0, *)) { NSData *stateHash = nil; if ([context respondsToSelector:@selector(domainState)]) { stateHash = [[context performSelector:@selector(domainState)] performSelector:@selector(stateHash)]; }else{ stateHash = [context evaluatedPolicyDomainState]; } eds = (char *)stateHash.bytes; edslen = (int)stateHash.length; } else { eds = (char *)[[context evaluatedPolicyDomainState] bytes]; edslen = (int)[[context evaluatedPolicyDomainState] length]; } CC_SHA256(eds, edslen, uviOut); *poutlen = CC_SHA256_DIGEST_LENGTH; } else { *poutlen = 32; gm_memset(uviOut, 0x01, 32); } }

Hello Apple Developer: I encountered some issues during development. I encrypted the secret key and stored it in the Keychain, but it failed when I tried to read it. I would like to ask if there is any problem with the code I wrote. Below is my code, including the storage and retrieval NSMutableDictionary *query = [[NSMutableDictionary alloc] initWithObjectsAndKeys:(id)kSecClassGenericPassword,(id)kSecClass, serviceID,(id)kSecAttrService, @YES,(id)kSecReturnData,nil]; CFTypeRef dataTypeRef = NULL; NSLog(@"SecItemCopyMatching"); OSStatus status = SecItemCopyMatching((__bridge CFDictionaryRef)(query), &dataTypeRef); NSLog(@"SecItemCopyMatching end status = %d",status); if (status == errSecSuccess) { *privateData = CFBridgingRelease(dataTypeRef); return 0; }else{ return status; } NSMutableDictionary *attributespri = [[NSMutableDictionary alloc] initWithObjectsAndKeys: (id)kSecClassGenericPassword, (id)kSecClass, serviceID, (id)kSecAttrService, outData, (id)kSecValueData, nil]; CFTypeRef dataRef = NULL; OSStatus priStatus = SecItemAdd((__bridge CFDictionaryRef)attributespri, &dataRef); if (dataRef) CFRelease(dataRef); return priStatus == noErr;
