Hi, I use AudioQueueNewInput() with my very own run loop and dedicated thread. But now it doesn't show the mic alert window. Howto fix this? AudioQueueNewInput(&(core_audio_port->record_format), ags_core_audio_port_handle_input_buffer, core_audio_port, ags_core_audio_port_input_run_loop, kCFRunLoopDefaultMode, 0, &(core_audio_port->record_aq_ref));

Hi everyone, I'm having a recurring issue with the "Sign in with Apple" integration in my web app, and I’m hoping someone here can help or share insights. Here’s the situation: I implemented "Sign in with Apple" following the official documentation, and it worked perfectly at first. After about two weeks, I started getting the "invalid_client" error when redirecting to the authentication page. I reviewed everything and discovered I hadn’t set up the email configuration properly in the Apple Developer Console. Once I fixed that, it worked fine again. Now, the same error ("invalid_client") has returned, and I’ve triple-checked every part of my configuration: The service ID, redirect URIs, and domain settings match exactly. The client_secret is generated correctly with all required fields (iss, iat, exp, aud, and sub) and signed with ES256. My server time is synchronized. Nothing has changed in my code or configuration since it last worked. This seems to be an issue on Apple’s end because everything was functioning perfectly before, and I’ve already resolved this once by updating settings in the Developer Console. Has anyone else faced this issue? Is there something I might be missing, or could this be a problem with Apple’s service? Any advice or guidance would be greatly appreciated!

Hi there, I'm currently working on a compatibility feature for Apple that allows the user to manage their keys and certificates from within our internal API. For this I need to retrieve all the items contained within keychains. I am looking at the documentation for SecItem API but so far I have not really found an obvious way to link these items together. My best guess so far is to perform two queries, grabbing all SecKeys from the keychains, pairing them up with public keys through SecKeyCopyPublicKey, then downloading all CertItems and pairing them with public keys with SecCertificateCopyKey, and then join the two using public keys. This sounds however somewhat involved and I was wondering if there was a better way of going about the process?

We run simple iOS Swift code triggered by a remote notification: UserDefaults.standard.set("key", forKey: "value") It runs fine when the app is active or inactive, but when the device is closed/locked and the code is triggered, we see a warning in Xcode: Couldn't write values for keys ( key ) in CFPrefsPlistSource<0x3018802d0> (Domain: com.example, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null), Contents Need Refresh: No): Path not accessible Not updating lastKnownShmemState in CFPrefsPlistSource<0x3018802d0> (Domain: com.example, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null), Contents Need Refresh: No): 767 -> 767 The issue is that there seems to be no way to catch that warning. The value is set, when it's re-read the value is correct. But the value is never written to disk, so after an app restart/update the value is gone, potentially has an old wrong value. This code runs without any interruption, it's just showing the warning on iOS 17.7.1 on iPad: UserDefaults.standard.set("key", forKey: "value") UserDefaults.standard.synchronize() print("value: \(UserDefaults.standard.string(forKey: "key"))") Should there not be a way to catch this, so the code can act accordingly to the circumstances? It would be good to know inside the code that the value is not persisted. I would expect that an exception is generated somewhere which can be caught. It seems .completeFileProtectionUntilFirstUserAuthentication enables files to be written to disk while the device is closed/locked, can something similar be used for UserDefaults.standard?

Hello, I have a public key of type Curve25519.KeyAgreement.PublicKey that I create from the raw representation using: Curve25519.KeyAgreement.PublicKey(rawRepresentation: Data(base64Encoded: "08sYq4gExgX+UApEwLaASkE+TZjAxG1FPYaT+mj2irk=")!) I'm trying to convert that key to a curve, but I don't see an equivalent function in CryptoKit for the Javascript function pk_to_curve25519. Can someone please help? For completeness, I'm trying to implement the handshake protocol that's a part of secure scuttlebutt. https://ssbc.github.io/scuttlebutt-protocol-guide/

We received a rejection today based on an invalid PrivacyInfo.xcprivacy file. It contained one extra space character was somehow added to a value field. Is there a tool that can check the validity of our PrivacyInfo.xcprivacy files?

In our application, we store user information (Username, Password, accessToken, Refresh token, etc.) in the keychain. However, after performing a hard reboot (unplugging and plugging back in), when we attempt to retrieve the ‘refresh token’ or ‘access token’ from the keychain, we receive the old token instead of the newly saved one.

Does macos app support passkey? Can I also use passkey's functionality if it's an internal release, not an Apple App Store release?

Private relay emails are ending up in the spam folder, even though SPF and DKIM are set up correctly.

Dear Apple Developer Support Team, I am writing to request assistance regarding an issue with the Apple Sign-In integration for my application, specifically in obtaining the email ID from the id_token. We are using the following Apple Sign-In authorization URL to initiate the sign-in process: https://appleid.apple.com/auth/authorize?response_type=code&response_mode=query&client_id=com.whattotrust.client&redirect_uri=https%3A%2F%2Fdev-web.whattotrust.com%2Fauth%2Fcallback After successfully authenticating the user and obtaining the authorization code, we use this endpoint to request the id_token and access_token: https://appleid.apple.com/auth/token While we are able to retrieve the tokens, we are experiencing issues when attempting to extract the user's email ID from the id_token. This issue has been consistent across multiple accounts. Despite successfully decrypting the id_token, the email field is either missing or unavailable. but with few emails we are getting email Could you please help us understand if there is an additional step or specific condition required to ensure that the email ID is included in the id_token? We would greatly appreciate any guidance on how to resolve this issue. Thank you for your support and assistance in resolving this matter.

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 I tried to launch my application from non-gui process (from launch daemon) NSworkspace openApplicationAtURL failed if I tried to run it when my device on the login screen. Everything is working if someone logged in, but on the login screen I have the error The application “TestApp” could not be launched because a miscellaneous error occurred. with code 256 NSWorkspace* workspace = [NSWorkspace sharedWorkspace]; NSWorkspaceOpenConfiguration* config = [NSWorkspaceOpenConfiguration configuration]; config.createsNewApplicationInstance = YES; config.activates = NO; config.promptsUserIfNeeded = NO; config.addsToRecentItems = NO; [workspace openApplicationAtURL: appURL configuration: config completionHandler:^(NSRunningApplication *app, NSError *error) { }]; Sometimes after the third try it works, sometimes not at all. I try to use "open" command, it works on MacOS Sequoia, but not working for operating systems below, I see this error The application cannot be opened for an unexpected reason, error=Error Domain=RBSRequestErrorDomain Code=5 "Launch failed."

I'm developing screen share utility, so I need somehow to launch my application on the login screen. Could someone please help me understand what is recommended way to launch application on the login screen?

I would like to be able to reset an user password through some automated scripts, would need help regarding that.

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!

Hi, I have a certificate, how can I display the certificate content in my Mac app just like Keychain Access app does. Can I popup the certificate content dialog just like Keychain Access app?

In the YouTube video WWDC24: Meet AccessorySetupKit | Apple two apps are demonstrated to showcase the functionality of AccessorySetupKit. Does anyone know where I can find the source code for these demo apps?

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.

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.
