Hi, Our team uses Xcode Cloud to run unit tests, and since around November, we’ve been frequently experiencing timeouts with the following type of process: @Test func hogeTest() async { // do something hoge.do() // wait until done await wait(condition: { hoge.isDone }) // test result #expect(hoge.isSucceeded) } private func wait(condition: () async -> Bool, timeout: TimeInterval = 0.5, pollingInterval: TimeInterval = 0.01) async throws { let deadline = Date().addingTimeInterval(timeout) while Date() < deadline { if await condition() { return } try await Task.sleep(nanoseconds: UInt64(round(pollingInterval * TimeInterval(NSEC_PER_SEC)))) } Issue.record("timeout") } Although sleep is supposed to wait for only a few milliseconds, there are cases where it takes more than 10 seconds, leading to a timeout. What could be causing this instability in the sleep duration? Additionally, if there are other recommended ways to implement polling and waiting in Swift Testing, I would appreciate it if you could share them. A feedback report (FB15899163) has already been submitted. Best regards,

Hello Apple Developer Team, I am facing an issue with remote notifications in my iOS app. When the app is in a terminated (kill) state, notifications are successfully received by the device, but none of the app's handlers (like _firebaseMessagingBackgroundHandler in Flutter) are invoked. This is impacting our ability to process silent notifications or perform background tasks reliably when the app is not running. Steps to reproduce: Send a remote notification with content-available: 1 in the payload. Confirm the notification is received by the device while the app is in kill mode. Observe that no background or foreground notification methods are triggered in the app. Expected Behavior: The app should invoke the background handler to process the notification payload, even in a terminated state. Observed Behavior: The notification is delivered to the device, but no app-level processing occurs because none of the methods are triggered. Can you please confirm if this is the intended behavior due to iOS limitations, or if there is a configuration or alternative solution to allow background handlers to execute in such scenarios? Any guidance or clarification would be highly appreciated. Thank you!

I work on an SDK, and one of the ways we distribute it is as a pre-compiled static XCFramework. As far as I know, it’s the nature of a static framework to not contain symbols since the framework will be embedded in the final app binary, and the symbols should then be generated. However, when testing the "Validate" function of the Xcode 16 deployment process, our users are receiving a warning that says the framework does not contain symbols. Is my assumption about static frameworks and symbols incorrect? Could this be a bug in Xcode 16? Should we modify something in our framework to inform Xcode that symbols are not needed?

Why did I receive a CONSUMPTION_REQUEST for the same transaction_id the day after I already received a REFUND for it? I received a CONSUMPTION_REQUEST, but due to a program error, I failed to submit the customer information. Later, I was notified with a REFUND, indicating that the transaction had been refunded. However, the next day, I received another CONSUMPTION_REQUEST notification for the same transaction_id.

I'm confused by documentation and information I found regarding compatibility between versions of Xcode and macOS. The site https://developer.apple.com/support/xcode/ is listing "Minimum OS required". To my understanding it means "this particular version of macOS and all later/newer versions". Also release notes for Xcode are consistently stating "Xcode xx.x. requires a Mac running macOS yy.yy.y or later." But I also found statements like " In general, new versions of macOS will not run old versions of Xcode." in this forum, see https://forums.developer.apple.com/forums/thread/760737, which is the opposite to "requires macOS version X or later". I'm also experiencing issues when trying to run Xcode 12.4 on macOS 14.5 (Sonoma), means XCode is not running. It would be great if some of Apple Engineers here would shed some light on it :-) Many thanks in advance! Cheers, Elena

Can someone give me an easy way to fix this code?

Hello, I am currently implementing a biometric authentication registration flow using WebAuthn. I am using ASAuthorizationPlatformPublicKeyCredentialRegistrationRequest, and I would like to know if there is a way to hide the "Save to another device" option that appears during the registration process. Specifically, I want to guide users to save the passkey only locally on their device, without prompting them to save it to iCloud Keychain or another device. If there is a way to hide this option or if there is a recommended approach to achieve this, I would greatly appreciate your guidance. Also, if this is not possible due to iOS version or API limitations, I would be grateful if you could share any best practices for limiting user options in this scenario. If anyone has experienced a similar issue, your advice would be very helpful. Thank you in advance.

Hello, I am currently working on implementing credential registration for biometric authentication using WebAuthn in an iOS app. I am using ASAuthorizationPlatformPublicKeyCredentialProvider to create a credential registration request based on the data retrieved from the WebAuthn options endpoint. At the moment, I am only using user.id, user.name, and challenge from the options response, and I am unsure how to utilize the other fields effectively. I would greatly appreciate advice on how to use the following fields: **Fields I would like to use: ** rp (Relying Party) I am retrieving id and name, but I am not sure how best to pass and utilize these fields. Is there an explicit way to use them? authenticatorSelection How can I set requireResidentKey and userVerification in ASAuthorizationPlatformPublicKeyCredentialRegistrationRequest? Also, what are the specific benefits of using these fields? timeout Is there a way to reflect the timeout value in the credential registration request, and what would be the best way to handle this information in iOS? attestation The attestation field can contain values such as none or direct. How should I reflect this in the credential registration request for iOS? I would appreciate a sample implementation or guidance on the benefits of setting this field. extensions If I want to customize the authentication flow using the extensions field, how can I appropriately reflect this in iOS? For instance, how can I utilize extensions like credProps? pubKeyCredParams Regarding pubKeyCredParams, which is a list of supported public key algorithms, I am unsure how to use it to select an appropriate algorithm in iOS. How should I incorporate this information into the request? excludeCredentials I understand that setting excludeCredentials can prevent duplicate registration, but I am not sure how to use past credential information to set it effectively. Any advice on this would be appreciated. **Current Code ** Currently, I have implemented the following code, but I am struggling to understand how to add and configure the fields mentioned above. let publicKeyCredentialProvider = ASAuthorizationPlatformPublicKeyCredentialProvider( relyingPartyIdentifier: "www.example.com" ) let registrationRequest = publicKeyCredentialProvider.createCredentialRegistrationRequest( challenge: challenge, name: userId, userID: userIdData ) let authController = ASAuthorizationController(authorizationRequests: [registrationRequest]) authController.delegate = self authController.presentationContextProvider = self authController.performRequests() In addition to the above code, I would be grateful if anyone could advise on how to configure fields like rp, authenticatorSelection, attestation, extensions, and pubKeyCredParams as well. Furthermore, I would appreciate any insights into the benefits of setting each of these fields in iOS, and any security considerations to be aware of. If anyone has experience with this, your guidance would be extremely helpful. Thank you very much in advance!

Hi, I tried to make a new branch of my project and upon doing so, all of my old files disappeared. They are no longer in my folder directory or available in Xcode. Please let me know if there is any way to recover these files. I don't see the files in my trash either.

I have a SwiftUI app that I've been working on in XCode 16.1. The project builds and runs in the simulators, on my mac and on my iPhone/iPad without any issues. I'm also able to build my unit test project and run them without any errors. The project has zero warnings in it. When I go to the Edit Schemes options and change the Run scheme to be a Release build with the Debug Executable unchecked I get a compiler error: Command SwiftCompile failed with a nonzero exit code I've attempted this Release Run with the following target devices in XCode: My iPhone 15 Pro Max (iOS 18.2 Beta 3) MacBook Air (M1) (15.2 Beta) iPhone 16 Simulator (iOS 18.1) Any iOS Simulator Device (arm64, x86_64) All 3 of these target have the same issue. Normally I would just debug the error from the logs but when I look at the build output I can't see any information in the log to tell me what happened. It looks like the source files are sent into the SwiftCompiler and the compiler fails without bubbling up the issue. I've provided the full error log export as a Gist HERE due to it's size. Is there anything in the log I'm missing? Is there a way for me to turn on more verbose logging during compilation of a Release Build? I created a brand new Multiplatform App in XCode and I added all of my source files to it. No project configuration settings were changed. I could build it successfully with the debug configuration. I then changed it to the Release configuration and experienced the same error. I can create another fresh project and make the same release configuration with none of my source files in it and get a successful build. I t seems there is something wrong with my source files and the release configuration but the compiler doesn't indicate what. I'm lost at this point as I can't figure out how to get a release build and can't seem to find any indication as to why.

I am using GoogleMobileAds package dependencies and now when I want to archive and export an app I get this two warnings : Upload Symbols Failed The archive did not include a dSYM for the GoogleMobileAds.framework with the UUIDs [13B55A37-D103-36E1-8D7B-FA4EAB2C8146]. Ensure that the archive's dSYM folder includes a DWARF file for GoogleMobileAds.framework with the expected UUIDs. Upload Symbols Failed The archive did not include a dSYM for the UserMessagingPlatform.framework with the UUIDs [A3941120-02A1-30B5-8C28-BFC0F9496E16]. Ensure that the archive's dSYM folder includes a DWARF file for UserMessagingPlatform.framework with the expected UUIDs. I have updated the packages to 11.9.0 (lasted) and Xcode 16 to 16 RC (lasted also) and I would like to know how to fix this... With Xcode 15 I have no problem !! I can export with no warnings ! But now with Xcode 16 no... Thanks for helping !

Hello fellow developers, My team has been running into a persistent INVALID_CLIENT error while trying to implement Sign In With Apple JS in our Nextjs app with signInWithPopup from firebase/auth. Here is the full error: Error getting access token from https://appleid.apple.com, OAuth2 redirect uri is: https://[redacted]/__/auth/handler, response: OAuth2TokenResponse{params: error=invalid_client, httpMetadata: HttpMetadata{status=400, cachePolicy=NO_CACHE, cacheDurationJava=null, cacheImmutable=false, staleWhileRevalidate=null, filename=null, lastModified=null, retryAfter=null, crossOriginEmbedderPolicy=null, crossOriginOpenerPolicy=null, crossOriginResourcePolicy=null, permissionsPolicies=[], headers=HTTP/1.1 200 OK, contentSecurityPolicies=[], originTrials=[], reportToHeaders=[], varyHeaderNames=[], cookieList=[]}} I've checked every thread on these forums and stackoverflow for solutions to this very common issue, and we tried them all. We made sure to verify that the Services ID, Apple Team ID, Key ID and Private key are all correctly used in the firebase console, we have regenerated our keys, all to no avail. We also contacted Apple Support via the Development And Technical option with Certificates, Identifiers, and Provisioning Profiles topics, but they directed us to code-level support, which excludes 3rd Party libraries so this does not seem appropriate for us. Does anyone have any idea of what might be wrong or suggestions for something we could try? We are able to get the pop up to open with an Apple login form, allow us to enter the credentials, but then when we hit continue the error occurs. We are using firebase version ^10.4.0 Any help would be greatly appreciated and let me know if I need to provide any additional info. Thank you.

Hi there - I maintain the react-native-apple-authentication module which allows react native developers to implement sign in with Apple When testing we noticed that code working perfectly in iOS17 Simulators now fails on iOS18/18.1 Simulators. Specifically, the credential status is always revoked when testing on an iOS18+ Simulator. The same code works perfectly on a real device running iOS18 or 18.1 so this appears to be a Simulator bug. This is problematic because App review is frequently performed on a Simulator, so there are false-negative test results for Sign In With Apple from reviewers when they use iOS18 emulators, resulting in App submission rejections. We're tracking this here, with some results posted and an example app in-repo that demonstrates the issue: https://github.com/invertase/react-native-apple-authentication/issues/356 It would be great to see the Simulator fixed so that it works correctly with Sign In With Apple again. Thanks

Hello - Asking a question that's probably been asked, and maybe a couple more. I bought a membership yesterday and received the email, I'm assuming it's "approved", but when I log in on developer account it says "PENDING". I will be the only user on my account. I already have the app, it's been tested by another party and all I need do is make some minor changes. So that's done, now I need to create a "debug or release testing distribution", but when I do that I get this error in xCode. Is this normal...until my status changes from "PENDING" to (guessing) APPROVED? And one further question. I am the only developer, and this app will only be used by one person as it's specialized for a single purpose. What are the option for that person to install the app? Is there a special section on the app store for such an app? Thanks, Gary

Been using Xcode's Download Container for a short time, and at first there were no issues. But lately, it doesn't always download all the files from my iPhone to the Mac. Sometimes cleaning the build folder works, other times not. As well, the same happens whether I am connected to my iPhone via cable, or wifi. Has anyone else had this issue?
