Can't generate keypair through SecKeyCreateRandomKey() on macOS Sequoia - internal error
I generate a keys using : let attributes: NSDictionary = [ kSecAttrLabel: label, kSecUseKeychain: getSystemKeychain()!, kSecAttrKeyType: kSecAttrKeyTypeEC, kSecAttrKeyType: kSecAttrKeyTypeECSECPrimeRandom, kSecAttrKeySizeInBits: 256, kSecPrivateKeyAttrs: [ kSecAttrIsPermanent: true, kSecAttrApplicationTag: tag, ] as [CFString : Any] ] var error: Unmanaged<CFError>? // Generate a new private key guard let privateKey = SecKeyCreateRandomKey(attributes, &error) else { logger.error("failed to create a keypair \(String(describing: error))") return (nil, nil) } I keep getting this error : failed to create a keypair Optional(Swift.Unmanaged<__C.CFErrorRef>(_value: Error Domain=NSOSStatusErrorDomain Code=-2070 "internal error" (internalComponentErr) UserInfo={numberOfErrorsDeep=0, NSDescription=internal error})) The above code works absolutely fine on macOS Sonoma and older OS. This looks like a regression in the Apple API SecKeyCreateRandomKey(). What is a good workaround for this ?

Keychain Update Prompt Missing After Password Change on macOS 15.0.1
I've encountered an issue with the keychain on macOS 15.0.1. When an admin account changes the password for a non-admin local account, the system should prompt to unlock the login keychain at the next login, giving the user an opportunity to update the keychain password. However, when I attempted to change a local account password using an admin account through system configuration on macOS 15.0.1, the system did not show such a prompt. Instead, it directly created a new login keychain. In the keychain directory, I could see that the old keychain had been renamed to login_rename_X.keychain-db. Additionally, this operation caused the Touch ID and passwords saved in the keychain to be cleared. Does anyone know how to handle this issue so that the local account is prompted to update the keychain password during login?

Question about the November 12 deadline
We noticed a change in the page Adding a privacy manifest to your app or third-party SDK that adds a deadline of November 12 past which invalid manifests will not be allowed in store submissions. Does this mean we can no longer use old versions of third-party SDKs which lack a manifest? (The ones that were allowed because we had already shipped with them.)

Can not Read Keychain On TestFlight
I have a sdk which reads and writes data to keychain everything works fine on local machine. But on testflight it can not read the data it previously wrote. every time app starts it tries to read but fails. I have other apps they works fine with the same sdk and same code on testflight and local. There is keychain access groups in entitlement file. the reason is not entitlement file. Any ideas?

Sign in with Apple
When we develop 'Sign in with Apple' function on our app, we visited https://appleid.apple.com to verify the account. However, appleid.apple.com is mapped to an American IP, and it is not suitable for our app which is operated in China. I wonder whether there is a China Mainland IP available for the verification? Thanks very much.

Sign in with Apple Credential State Failing on watchOS for Existing Users
Hello everyone, I’m encountering an issue with Sign in with Apple in my watchOS app and would appreciate any guidance. Background: Initially, I did not have the Sign in with Apple capability enabled on my watchOS app. I have since enabled the capability and grouped it with my iOS app. For new user accounts created after this change, everything works perfectly: The credentialState check returns .authorized on both iOS and watchOS. However, for existing user accounts (created before enabling the capability on watchOS): The credentialState check returns not authorized on watchOS. The check still returns .authorized on iOS for these accounts. Error Details: When calling ASAuthorizationAppleIDProvider.credentialState(forUserID:) on watchOS for existing accounts, I receive the following error: Error Domain=AKAuthenticationError Code=-7074 "(null)" My Suspicions: I believe the issue arises because the existing Sign in with Apple tokens are only associated with the iOS app’s bundle identifier and not with the watchOS app’s bundle identifier. Since the capability wasn’t enabled on the watchOS app when these accounts were created, their tokens aren’t valid for the watchOS app. Questions: Is this the correct explanation for why the credentialState check fails on watchOS for existing accounts, resulting in the AKAuthenticationError Code=-7074 error? Can I update or migrate the existing accounts so that their Sign in with Apple tokens are valid for the watchOS app as well? If so, how can this be achieved? Are there any best practices for handling this situation without requiring users to re-authenticate or removing the credentialState check from the watchOS app? Goal: I want to maintain the credentialState check on the watchOS app because it works correctly for new accounts and is important for security. I’m looking for a solution that allows existing users to continue using the app on their Apple Watch without interruption or additional sign-in steps. Any help or suggestions would be greatly appreciated! Thank you!

App access to another app folder
I am working on a personal use app, to transcribe audio files. I have over 1000 Voice Memos of ideas for a dog training app and book, recorded while... walking dogs, of course. I seem to not have the built in transcription option, either because Sonoma doesn't support it or my region doesn't, but I have learned a lot of Swift building an app that works great fort files in a folder in Documents. I have also found the path to to all the Voice Memo recordings. But when I try to read the contents of the folder to build the queue for transcription I get The file “Recordings” couldn’t be opened because you don’t have permission to view it. I expected this to be locked down, and some searching brought me to this and I have added Access User Selected Files (Read Only) = YES to the entitlements file, but I am not seeing where in the TARGETS editor I would assign com.apple.security.files.user-selected.read-only. If I add it as a key under info I don't get a popup to select, either in Xcode or when running the app. If I try to add that key to the entitlements file it doesn't allow for selection either. I am sure I am just missing something in the documentation, likely as a result of being an Xcode & Swift noob. So, if I CAN do this and I am just missing something, can someone point the way? And if a folder inside another app is just verboten, manually copying those files to a documents folder for processing won't be the end of the world.

Endpoint Security sysex in a User Agent installer?
Firstly, I want to keep my GUI app available for download on the Mac App Store, which means I need to provide the Endpoint Security functionality in some other executable, such as a daemon. I'm going to use a User Agent for user-aware background processing. Instead of the typical use of adding an Endpoint Security system extension to a macOS app, could I instead add the sysex to my User Agent bundle? I like the benefits of coupling the sysex to the client that will interact with it, and this would also allow me to not have to worry about managing a daemon. I could simply provide the User Agent in a downloadable installer signed with my Developer ID certificate.

AuthenticationServices framework returns an invalid signature when signing in with a passkey in a Swift app for iOS/macOS
I am trying to implement a login page in SwiftUI for an idp that relies on passkeys only, following the sample code from the food truck app. The registration of a new passkey works fine but when it comes to signing in, ASAuthorizationPlatformPublicKeyCredentialProvider().createCredentialAssertionRequest returns a signature that cannot be verified by the server. On safari (and other browsers) the signing in&up process works fine and additionally, a passkey registered from the swift app works on the web, which leads me to believe there is an issue in the AuthenticationServices framework as every other steps works without any problem. The verification of the signature happens on the server side (after several validation steps of the other parameters) with WebCrypto.subtle.verify(verifyAlgorithm, key, signature, data); With the data argument being a concat of the clientDataJSON and the authenticatorData and for an apple authenticator, the key argument (which is the public key stored by the server) is an EC2 key with the following verifyAlgorithm argument: verifyAlgorithm = { name: 'ECDSA', hash: { name: SHA-256 }, }; After carefully analyzing multiple responses, coming both from the app and safari, either on iOS or macOS, I can safely say that the ASAuthorizationResult.passkeyAssertion returns the expected values for: rawAuthenticatorData rawClientDataJSON credentialID userID Which all match the expected values during the server-side validation. The only remaining value from the ASAuthorizationResult.passkeyAssertion is the signature, which as mentioned above, is invalid when verified by the server. I already submitted a bug report (FB15113372) as well as a DTS request, but haven’t received any feedback yet. In order to further narrow down the problem, I replicated the signature verification process in a sage notebook. I got the same result: the signature produced in Safari is fine, but the one from the Swift app is invalid. I collected some thoughts of potential issues in this notebook, but I still haven’t been able to draw a clear conclusion on why does this issue occur. Hence if anyone has knowledge of this issue or has a similar problem with signature verification, their advice is most welcomed. Thank you in advance for your help PS: All the recent tests were made on the latest publicly available OS releases (iOS 18.01, macOS 15.0.1) and Xcode 16.0

Accessing camera from SSO extension
I'm trying to create an "Extensible Enterprise SSO" extension as described in the Introducing Extensible Enterprise SSO tech talk. My SSO extension works fine, but I want to be able to access the camera (via AVFoundation) from within the SSO extension. According to this thread (which I can't seem to be able to reply to) - it should be possible to access the camera from within an SSO extension, however this doesn't work for me. When I try to access the camera, I get the permission dialog, but after accepting, the camera preview is empty and no camera frames are produced. I don't get any errors/warnings in the logs, but it immediately fires AVCaptureSession.wasInterruptedNotification notification with AVCaptureSessionInterruptionReasonKey = 1 which corresponds to videoDeviceNotAvailableInBackground. However, the SSO extension view controller is clearly not in the background, so is this a bug - or are there special rules for requesting camera permission in an SSO extension? The same camera access works fine in the host app, just not inside the extension. Interestingly, accessing the camera in a WKWebView using various webcam test pages, doesn't work either. All of these tests have been on iPadOS 18.

When performing device certificate authentication on iOS18, it takes time to respond.
We are using device certificates for authentication when logging into our web page. After updating an iPhone 12 to iOS 18, the authentication process takes up to two minutes to respond. Upon investigating IIS, it was found that the certificate is not being presented from the iPhone, resulting in a timeout. This issue is affecting our operations, and we need a solution urgently. Could you please advise on how to resolve this?

CryptoTokenKit framework usage
Hi, I’m currently working on an app that uses a third-party SDK to perform smart card authentication via PKCS#11 APIs. Specifically, the app interacts with the smart card to retrieve certificates, detect the card reader, and perform encryption and decryption operations on provided data. I’m wondering if it's possible to replace the PKCS#11 APIs and the third-party SDK with Apple's CryptoTokenKit framework. Does CryptoTokenKit provide equivalent functionality for smart card authentication, certificate management, and encryption/decryption operations? Additionally, I’ve come across the following CryptoTokenKit documentation: CryptoTokenKit API - TKSmartCardSlotManager Could you provide an example code or any guidance on how to implement this functionality using CryptoTokenKit, particularly for interacting with smart cards, managing certificates, and performing cryptographic operations? Thank you for your assistance.

Gatekeeper scans app before it finishes copying
Hi all, I found an issue by chance where, when we copy an .app bundle (a large one), Gatekeeper can choose to try to scan the app before the file copying finishes (without the app having been launched). This of course fails, and then the app can't open because "it's damaged", even though spctl and codesign checks of the completed copied app come out fine. Then Gatekeeper remembers this setting forever, not rescanning the app. I'm wondering if anyone else has seen this happen and if so, if there's a best practice for keeping Gatekeeper's hands off until the copy is done? I imagine copying into a folder not named .app, then renaming it might work, or maybe saving the plist or main binary copy until last, although both require a more complex copy operation. Maybe there's a more elegant way? Thanks!
