Hi all, I'm trying to integrate Apple’s DeviceCheck API into my Flutter iOS app. I already have everything set up on the backend — the Apple private key, key ID, team ID, and DeviceCheck capability. The backend is generating and signing the JWT correctly and making requests to Apple. However, I’m currently stuck on the frontend (Flutter): 👉 How can I generate the device_token required by the DeviceCheck API (via DCDevice.generateToken) in a Flutter iOS app? I understand that DCDevice.generateToken() must be called from native Swift code. I previously attempted to use a MethodChannel to bridge this in Swift, but would prefer not to write or maintain native Swift code if possible. I've looked for a prebuilt Flutter package to handle this, but nothing exists or is up-to-date on pub.dev. Main Question: Is there any Apple-supported way to generate the device_token for DeviceCheck from a Flutter app without writing Swift code manually? If not, is DCDevice.generateToken() the only possible approach, and must I implement this via Swift and Flutter platform channels? Thanks!

I have a swift project with a Watch companion. Since the update of Xcode in 16.3 version after updating MAcOs , Watch OS, iOS to the latest version . It is quasi impossible for me to make Xcode work with my series 10 Watch. I have a lot of alert box, messages in the "device & Simulator" tool like this Previous preparation error: A connection to this device could not be established.; Timed out while attempting to establish tunnel using negotiated network parameters. And many message telling me that Xcode is preparing the Watch , then that it has lost the connexion. I have to wait some minutes after EACH run of the App to test it again. This is very annoying . Some of the alerts I have : And the best to know , is that I can run the APP outside of Xcode , it works, Connects to the iPhone, fetch data and so. the iPhone sees the Watch without and problem. Reboots can solve for a few minutes the problem. But that is not a solution.

Recently, I had an error when building a project with xcode16.3. I'm not sure if it's caused by xcode16.3.

Hi I am a new self taught developer who is atm working on the backend of my app. My app successfully collects location of users and stores it to cloudkits public database. I now want to write a python script and run it on a local server on my windows terminal which fetches users who are in a certain proximity to each other so i can trigger a flow on the app. Can someone first of all tell me if this is even possible the way im attempting it. Also atm all i am doing is generating a server to server key which makes me generate a public and private key and i use the private key file eckey.pem plus key id plus container plus team ID to query the required data. but when i run it i get a 401 error (no authorization). I am so stumped as there arent many resources available to help direct me to the right path. Can someone please offer some help/insight/confidence. thanks alot

Hi there, I'm currently learning how to write some code using Swift Playgrounds on my Mac, and I'm wondering if there's a way to install the code I create onto my iPhone, like a regular app. I've searched online quite a bit but haven't found any clear or definitive answers. Many resources mention a "Run on iPhone" option in Swift Playgrounds, but I don't see that button in my version. I even installed Xcode and connected my iPhone to my Mac, following the instructions I found, but the "Run on iPhone" option still doesn't appear in Playgrounds. I've updated my Mac, iPhone, and Playgrounds to the latest version. Thank you for your help!

I have an iOS app and that has CarPlay enabled. I have Siri capability and the feature has been tested in Car. The voice commands are working perfectly fine. However, I am facing a weird issue as described below, The key NSSiriUsageDescription, is set to custom text in info.plist. After generating archive, I exported and checked the package contents, in which the the key NSSiriUsageDescription was reset to default text(Describe why your app needs Siri access) in the info.plist. I do not have any dynamic build process that's writing to the info.plist. Only the Siri key is being reset, rest of keys like camera/location permissions are intact. Kindly suggest what needs to be done at my end

Hi everyone, I’m experiencing a frustrating delay with my Apple Developer Program enrollment and I’m hoping someone here can help or escalate the issue. I had previously completed the enrollment process and was approved, but after opening the Apple Developer app on my iPad, the entire progress reset for some reason. I was forced to start the process again from scratch, including submitting all required documents. Last time, my documents were verified and approved within 7 days. However, this time, it’s been over a month since I submitted my documents and there's been no progress. I contacted Apple Developer Support, but they responded saying it would take an “undetermined amount of time,” without providing any explanation, timeline, or guidance. That’s extremely concerning, especially since I’ve already gone through this once before. This delay is affecting my ability to move forward with game releases and business plans. I’m more than willing to provide any additional documentation if needed, but I’m currently stuck with no idea what’s going on. Can someone from the Apple team please: Check the status of my enrollment using Enrollment ID: 772673548 Let me know if there are any issues that require action from my side Or help escalate this for review? Any help or guidance would be greatly appreciated. Thank you, Shamsad M

Hi, I am getting an error stating "Argument passed to call that takes no arguments". I want this Apple Watch App to measure and store RR Intervals from the PPG sensor on the Apple Watch for Heart Rate Variability calculations. Please help me fix this, I can't figure it out. Here is my code: heartbeatQuery = HKHeartbeatSeriesQuery(predicate: predicate, dataReceivedHandler: { (query, timeSinceLastBeat, ended, error) in // Switch to main thread for UI updates DispatchQueue.main.async { if let error = error { print("Heartbeat query error: (error.localizedDescription)") self.fetchErrorMessage = "Heartbeat query error: (error.localizedDescription)" // Consider stopping the workout session if the query fails critically // self.stopWorkoutSession() return } if ended { print("Heartbeat query indicates series ended.") } // Append valid RR intervals if timeSinceLastBeat > 0 { self.rrIntervals.append(timeSinceLastBeat) self.beatCount += 1 } } // End DispatchQueue.main.async }) // End query data handler // --- END OF PROBLEMATIC INITIALIZER --- // Execute the query if it was created successfully It recommends the fix as removing this part: '(predicate: predicate, dataReceivedHandler: { (query, timeSinceLastBeat, ended, error) in // Switch to main thread for UI updates DispatchQueue.main.async { if let error = error { print("Heartbeat query error: (error.localizedDescription)") self.fetchErrorMessage = "Heartbeat query error: (error.localizedDescription)" // Consider stopping the workout session if the query fails critically // self.stopWorkoutSession() return } if ended { print("Heartbeat query indicates series ended.") } // Append valid RR intervals if timeSinceLastBeat > 0 { self.rrIntervals.append(timeSinceLastBeat) self.beatCount += 1 } } // End DispatchQueue.main.async })' But after I remove that it says "Cannot assign value of type 'HKHeartbeatSeriesQuery.Type' to type 'HKHeartbeatSeriesQuery'" PLEASE HELP ME Thanks

Hello Elf Team, I sent the game a day ago and reached out for a quick review to meet my company's event deadline, but I am still waiting for the review to begin. I contacted via the contact form but have not received any response. Is there anyone from the forum who can help expedite this or provide advice on how to proceed? Thank you!

Is anybody able to save the autocreated testplan successfully with Xcode 16.3? I get a crash no matter what (different filenames, locations, machines, ...). Now created a template project: same thing. Xcode Version 16.3 (16E140) on macOS 15.5 (24F74) Known issue, or am I holding it wrong?

I'm working on dext project (c++), Base SDK and Supported Platforms are set to DriverKit. #include causes errors: error "The iostreams library is not supported since libc++ has been configured without support for localization." error "<locale.h> is not supported since libc++ has been configured without support for localization." Also it's not possible to define custom log object: undeclared identifier 'os_log_create'. <os/log.h> included and os_log function is compiled correct. macOS as additional SDK did not help. Thanks a lot for any hint.

I have an iOS app, and I am trying to add a companion WatchOS app. My iOS app depends on 2 libraries: GoogleMobileAds FirebaseAnalyticsWithoutAdIdSupport When I add a new target for WatchOS, the preview build starts to fail. I am not adding any libraries to WatchOS. The Google Ads and Firebase Analytics libs are only under the iOS target. I am unable to run the preview, I get an error when trying to build the watch scheme. The preview does not work. The build just crashes. I've included the error log below. But, here are the steps I've tried so far: Delete folders inside Derived Data Run a clean build (Cmd + Option + Shift + K) Delete scheme and create a new one Reset Package Cache Restart Xcode Restart Macbook But, it just does not work. I do not understand why the watchOS target is erroring for "GoogleUserMessagingPlatform" and "GoogleMobileAdsTarget" when those packages are not linked/used for the watchOS.

hello, I got a question about coreml. I loaded the coreml model in the project and set the computing unit to CPU+GPU. When I used instruments to analyze the performance, I found that there was an overhead of prepare gpu request before each inference. I also checked the freezing point graph and found that memory was frequently allocated. Is this as expected? Is there any way to avoid frequent prepares? I have tried some methods, such as memory sharing of predict interface input parameters, but it seems to be ineffective.

I need to elicit the location of the user in the Siri intents and so I call: override init(){ super.init() self.locationManager=CLLocationManager() self.locationManager.delegate = self; self.locationManager.startUpdatingLocation() self.locationManager.requestWhenInUseAuthorization() } Still neither public func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) nor public func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) are ever called, notwithstanding the presence of the correct entry in the info.plist, the inclusion of the library and the indication of the delegation with: class IntentHandler: INExtension, INSendMessageIntentHandling, CLLocationManagerDelegate, UISceneDelegate are ever called. Is there any problem with CLLocation manager on intents? What would be a big problem as there is no way to share information with the main app!

Hi, While I understand that some enrollment reviews may take time, it has now been nearly a month since we submitted our company enrollment on April 11, and unfortunately, we still have no concrete updates or next steps. As a small business, this extended delay is significantly affecting our operations. We are unable to proceed with our product launch, engage with partners, or move forward with development work. Each passing day adds to the financial and operational pressure we’re facing. To be completely transparent, we honestly don’t believe there is a large set of documents or verifications that would justify such a long review. Our company’s D-U-N-S information has been provided and contains clear, publicly verifiable details about our registration and address. Beyond that, there is no additional documentation that should require extended evaluation. From our research, we’ve learned that some enrollments may get stuck in the review pipeline indefinitely unless manually escalated — and some companies only managed to resolve the issue after getting in touch with senior contacts or executives. We kindly ask — and sincerely hope — that instead of a standard response confirming the enrollment is “under review,” we can receive a more concrete update: what stage it is truly at, whether any verification is pending, and whether manual intervention is required.

Neither a google search, nor a search of the Apple forums give me a clue as to how to locate or fix the following message I get from Xcode. CLIENT: Failure to determine if this machine is in the process of shutting down, err=1/Operation not permitted This error message came from attempting to build and execute an iOS App which ran just fine the last time I built it. Now, that was actually a little over two years ago. This is an iOS app, which I've run successfully for more than a year on macOS, and that, "My Mac (Designed for iPad)", is what my build target for this run was. Any ideas? Anyone? If this is a "known condition", just why doesn't a friendly internet search or a search of the Apple forums NOT tell me what it means, or what causes the message. Of course, I've upgraded the OS a few times, and updated Xcode as well, but have just not had any time to monkey around with my pet code project. Now that I've gotten some time, and I want to see what's new since March of '23, I finally remember where I stashed my code repository and decided to take it for a spin. Sure, I expect(ed) to see Xcode tell me that the version of Swift has been updated, and maybe some code constructs need to be fixed. But, NO, the code compiles fine. The first build attempt told me that I needed to update my provisioning profiles, and sign-in and agree to the updated developer agreements, which I did. Not so unhelpful was the code window in the debugger: libswiftCore.dylib`swift_willThrow: -> 0x1aeb7b2a0 <+0>: pacibsp 0x1aeb7b2a4 <+4>: str x19, [sp, #-0x20]! 0x1aeb7b2a8 <+8>: stp x29, x30, [sp, #0x10] 0x1aeb7b2ac <+12>: add x29, sp, #0x10 0x1aeb7b2b0 <+16>: adrp x8, 365651 0x1aeb7b2b4 <+20>: add x8, x8, #0x88 ; _swift_willThrow 0x1aeb7b2b8 <+24>: ldapr x8, [x8] 0x1aeb7b2bc <+28>: cbnz x8, 0x1aeb7b2cc ; <+44> 0x1aeb7b2c0 <+32>: ldp x29, x30, [sp, #0x10] 0x1aeb7b2c4 <+36>: ldr x19, [sp], #0x20 0x1aeb7b2c8 <+40>: retab 0x1aeb7b2cc <+44>: mov x0, x21 0x1aeb7b2d0 <+48>: mov x19, x21 0x1aeb7b2d4 <+52>: blraaz x8 0x1aeb7b2d8 <+56>: mov x21, x19 0x1aeb7b2dc <+60>: b 0x1aeb7b2c0 ; <+32> Still not much to go on. I decide to see if it was a macOS vs. iOS issue, so did a clean build folder and tried running on an iPad simulator, "iPad (10th generation)". Now, I have a blank white screen on my simulator and not much to go on in the code window. import SwiftUI @main struct JottoApp: App { Thread1: Breakpoint 1.1 var body: some Scene { WindowGroup { ContentView() } } init() { UITableView.appearance().backgroundColor = UIColor.clear } } Any and all help with this error message will be appreciated.

I've recently upgraded to Sequoia and Xcode 16.3 (now 16.4RC) and a significant change I've noticed vs 16.2 is that the height of UINavigationBar components in storyboards and XIBs is incorrect. Xcode 16.2: Xcode 16.4: This only affects simulated metrics in storyboard / XIB files. I have been unable to find any discussion of this issue anywhere online. Is this actually an Xcode bug that has gone unnoticed / unfixed or is there some underlying intentional change here that I'm unaware of?
