Is there a way to access the Core NFC Framework from within a watchOS app?

I noticied that my workout session is sometimes being killed by apple when the app is in the background and it seems that the func workoutSession(_ workoutSession: HKWorkoutSession, didChangeTo toState: HKWorkoutSessionState, from fromState: HKWorkoutSessionState, date: Date) { is only being called when the app comes back into the foreground. I wonder if there is a way for us to get notified when the workout is about to die or has already been killed. Thanks

Hi, it seems like the wachOS sysdiagnose debug profile is no longer valid and needs to be updated. Any idea to whom we should reach out to get this fixed? I am talking about the profile linked here: https://developer.apple.com/bug-reporting/profiles-and-logs/?platform=watchos Kind regards Alex

Hi, I have a watchOS app that records audio for an extended period of time and because the mic is active, continues to record in background mode when the watch face is off. However, when a call comes in or Siri is activated, recording stops because of an audio interruption. Here is my code for setting up the session: private func setupAudioSession() { let audioSession = AVAudioSession.sharedInstance() do { try audioSession.setCategory(.playAndRecord, mode: .default, options: [.overrideMutedMicrophoneInterruption]) try audioSession.setActive(true, options: .notifyOthersOnDeactivation) } catch { print("Audio Session error: \(error)") } } Before this I register an interruption handler that holds a reference to my AudioEngine (which I start and stop each time recording is activated by the user): _audioInterruptionHandler = AudioInterruptionHandler(audioEngine: _audioEngine) And here is how this class implements recovery: fileprivate class AudioInterruptionHandler { private let _audioEngine: AVAudioEngine public init(audioEngine: AVAudioEngine) { _audioEngine = audioEngine // Listen to interrupt notifications NotificationCenter.default.addObserver(self, selector: #selector(handleAudioInterruption(notification:)), name: AVAudioSession.interruptionNotification, object: nil) } @objc private func handleAudioInterruption(notification: Notification) { guard let userInfo = notification.userInfo, let interruptionTypeRawValue = userInfo[AVAudioSessionInterruptionTypeKey] as? UInt, let interruptionType = AVAudioSession.InterruptionType(rawValue: interruptionTypeRawValue) else { return } switch interruptionType { case .began: print("[AudioInterruptionHandler] Interruption began") case .ended: print("[AudioInterruptionHandler] Interruption ended") print("Interruption ended") do { try AVAudioSession.sharedInstance().setActive(true) } catch { print("[AudioInterruptionHandler] Error resuming audio session: \(error.localizedDescription)") } default: print("[AudioInterruptionHandler] Unknown interruption: \(interruptionType.rawValue)") } } } Unfortunately, it fails with: Error resuming audio session: Session activation failed Is this even possible to do on watchOS? This code worked for me on iOS. Thank you, -- B.

I am a watchOS 10.0 device, try to open the developer mode, according to the official website to enter the Settings > Privacy > Developer Mode. But I don't see the developer mode option, how do I turn on the developer mode for watchOS 10.0 device?

I'm building complications using WidgetKit and SwiftUI. The complications work, but the previews don't appear right away when applying the .watchface. How can I ensure the complication previews show up immediately when a user adds the watch face? Any guidance is appreciated.

Good morning, I come to you for a question: When I install my application on my iPhone for the first time, and I install the watch application from the native "Watch" application, the Watch Connectivity function does not work, I have to do the installation from Xcode to the watch for this function to work. Is this normal? if yes, the problem will not arise during a publication? I have the same problem when using watch and iPhone simulators, WatchConnectivity does not work. I am this error code in Xcode: -[WCSession handleIncomingUserInfoWithPairingID:]_block_invoke delegate (null) does not implement session:didReceiveUserInfo:, discarding incoming content Here is the code for the iPhone and the watch: In my iPhone app: import WatchConnectivity let userDefaultsDataVenantWatch = UserDefaults.standard class PhoneDataModel : NSObject, WCSessionDelegate, ObservableObject { static let shared = PhoneDataModel() let session = WCSession.default @Published var TableauSynchroIphoneVersWatch : [String:String] = ["0":"0"] @Published var dataWatchVersIphone: [String:String] = ["":""] override init() { super.init() if WCSession.isSupported() { session.delegate = self session.activate() } else { print("ERROR: Watch session not supported") } } func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) { if let error = error { print("session activation failed with error: \(error.localizedDescription)") return } } func sessionDidBecomeInactive(_ session: WCSession) { session.activate() } func sessionDidDeactivate(_ session: WCSession) { session.activate() } func session(_ session: WCSession, didReceiveUserInfo userInfo: [String : Any]) { guard let newCount = userInfo["TableauSynchroIphoneWatch"] as? [String:String] else { print("ERROR: unknown data received from Watch TableauSynchroIphoneWatch") return } DispatchQueue.main.async { print(newCount) } } } In my Watch app: import WatchConnectivity let userDefaultsDataVenantIphone = UserDefaults.standard var TableauVenantIphone:[String:String] = ["":""] class WatchDataModel : NSObject, WCSessionDelegate, ObservableObject { static let shared = WatchDataModel() let session = WCSession.default @Published var TableauSynchroIphoneWatch : [String:String] = ["0":"0"] override init() { super.init() if WCSession.isSupported() { session.delegate = self session.activate() } else { print("ERROR: Watch session not supported") } } func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) { if let error = error { print("session activation failed with error: \(error.localizedDescription)") return } } func session(_ session: WCSession, didReceiveUserInfo userInfo: [String : Any]) { guard let newCount = userInfo["TableauSynchroIphoneVersWatch"] as? [String:String] else { print("ERROR: unknown data received from Watch TableauSynchroIphoneWatch") return } DispatchQueue.main.async { print(newCount) } } } Thank for your answers !

I understand that the Nearby Interaction framework is available on watchOS 8+, and I want to make a watch app that displays distance estimation between multiple watches (not iPhones) using UWB through Nearby Interactions. I see in the documentation that an iPhone can discover multiple device "discovery tokens" and create NISessions with them using the Multipeer Connectivity framework, but it looks like the Multipeer Connectivity framework is not available on watchOS? So, how might I make an independent watch app that can discover multiple nearby watches and setup NISessions with them? Thanks!

It's not just me that the watch doesn't show up in Xcode 15.3, Watch 10.4, iOS 17.4.1, right? In Xcode, the Mac and iPhone are connected and displayed, but only the watch is not working. And when I run the complication app, oddly enough, it prompts to install the app on the iPhone device's watch app? It's really strange, isn't it? But the installation doesn't actually happen. It seems like a funny thing with Apple. Does anyone know when this will be fixed?

Could you please provide clarification on whether WatchOS currently supports the real-time or on-demand measurement of skin temperature and ambient temperature? If so, Could you also guide us on the relevant APIs or resources available for incorporating these features into out applications?

I currently have an app that is a companion app alongside the iOS app. I wonder if it is possible for me to make this app both a standalone and a companion app. Essentially if someone does not have an iphone they can still use the app. Is this possible?

When I connect a speed and cadence sensor to my Apple Watch in Bluetooth settings I expect to see the following HKQuantity types in workoutBuilder:(HKLiveWorkoutBuilder *)workoutBuilder didCollectDataOfTypes HKQuantityTypeIdentifierCyclingSpeed, HKQuantityTypeIdentifierDistanceCycling, and HKQuantityTypeIdentifierCyclingCadence. However, after starting an HKWorkoutSession I only get updates for HKQuantityTypeIdentifierDistanceCycling. I know that these metrics are being updated because the Apple Workout app displays them. I have authorized my app to read and write these quantity types, so what could I be missing here? Are these quantities only available to the workout app, as I haven't found a third-party app that sees these metrics when the sensors are connected this way?

How can I implement a feature in my iOS and watchOS app to prompt users to download it when they try to apply a custom watch face shared from my app, as shown in the example image? We're using WidgetKit for Complications.

Hi there, I think I may have caught a bug in the iOS system. Please confirm. Problem Newly installed Watch-Only and Independent apps on the Apple Watch do not have a network connection when paired with an iPhone until the iPhone is rebooted. Please see the attached screenshot; the iPhone indicates 'WiFi and Cellular policy: kDeny'. Use Case For our end-users, they will install the Watch-Only app directly from the App Store on the Apple Watch, and of course, their watch is paired with their iPhone. In this case, the Watch-Only app has no network connection at all after installation. The user has to reboot the iPhone once, and then the Watch-Only app can access the network. It is unacceptable for the end-users. System Info WatchOS: 10.1.1 Watch Model: A2770, Apple Watch Series 8 (GPS only) iOS Version: 17.4.1 iPhone Model: iPhone 15 XCode: 15.3 How to reproduce Please download the very simple sample code attached. It features the official URLSession Demo Code, which initiates a default URLSession to access https://www.example.com. ContentView.swift Prepare an iPhone and an Apple Watch, then connect the watch to the iPhone and ensure they are paired correctly. Ensure that your iPhone properly connects to a working WiFi network. Now, connect both your Apple Watch and iPhone to Xcode and run the code on the watch. Xcode will then install the Watch-Only app on your watch. After installation, click the 'Click' button on the watch app, and you will receive an error message stating 'The Internet connection appears to be offline...' Now, check the Console output of your iPhone and filter by 'wifi policy'. You will see logs stating 'Adding CU Policy: Bundle IDs: (the-bundle-id) Wifi policy: kDeny Cellular policy: kDeny'. Now, reboot your iPhone and wait for it to reconnect to the WiFi network. Check the Control Center on your watch to ensure the little green iPhone icon is displayed, indicating that your watch is now paired correctly with the iPhone. Click the 'Click' button again on the watch app, and this time it will work perfectly. To repeat the process, simply uninstall the watch app from your watch, and run the sample code again. Xcode will reinstall the app onto the watch. This time, the app will not work until you reboot the iPhone again.

Hello, I have a TabView containing multiple views where one of them contains a list of items. The digital crown on the apple watch does not allow me to scroll the items in the tabview but only scrolls the list of items. Is there any way to disable that the scrolling of the list is done by the wheel or even a way to prioritize the digital crown to scroll the tabView and not the list? Thanks

This page describes the procedure to create deep links in iOS. I was able to launch an IOS Companion app (name of the app in my case) using its deep link. But the same is not working in AppleWatch. This is my plist to register a custom scheme - Companion: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CFBundleURLTypes</key> <array> <dict> <!-- <key>CFBundleTypeRole</key> <string>Viewer</string> --> <key>CFBundleURLName</key> <string><some unique ID></string> <key>CFBundleURLSchemes</key> <array> <string>Companion</string> </array> </dict> </array> </dict> </plist> I have implemented onOpenURL(perform:) to handle app launches using a deep link (url). var body: some Scene { WindowGroup { ContentView() .onOpenURL(perform: { (link: URL) in Log(String(format: "Link = %@", link.absoluteString)) // Use then deep link }) } } In iOS, I tested deep links in two ways: Wrote the full deep link in Notes app and tapped it. Created another app called AppLauncher with a Button saying 'Launch using Deep link'.... which when clicked opens the deep link using open(_:options:completionHandler:). Both the approaches work in iOS, but in watchOS, I can only try 2 because Notes app is not available for AppleWatch. So, I created another watchOS app called AppLauncher, which displays a SwiftUI Button saying 'Launch using Deep link', which when tapped, tries to open the link using openSystemURL(_:). But as mentioned in the documentation (linked earlier), Opens the specified system URL. this API only works for links associated with System apps i.e., Apple's call and message apps. So, how else can I use deep link to launch another app? I believe it's possible to launch an app using its deep link because the info.plist keys required to define a deep link scheme association (CFBundleURLTypes, CFBundleURLSchemes etc) is valid for watchOS too.

I am trying to get iPhone and watch simulator to send message to each other. I am getting this error(s) all the time: Error Domain=WCErrorDomain Code=7012 "Message reply took too long." UserInfo={NSLocalizedDescription=Message reply took too long., NSLocalizedFailureReason=Reply timeout occurred.} -[WCSession _onqueue_notifyOfMessageError:messageID:withErrorHandler:] 0F2558A6-6E42-4EF1-9223-FBC5336EE490 errorHandler: YES with WCErrorCodeMessageReplyTimedOut Is there are some guideline on how to connect them together? Maybe I a missing some step. For clarification, sometimes they do connect but it feels like pure luck. Please help.

Enable Developer Mode - Missing Trust this computer - Missing, if the prompt happens and you accidentally tap the verbiage or the crown before scrolling to the buttons, you never ever see the trust this computer again. Double tapping the side button or crown to kill apps is a game of roulette. If you don’t swipe the app in mere seconds the list disappears or one of the background apps becomes active. After upgrading all watches to 10.4 and pairing to a phone guess what? Enable developer mode - missing. Now I have a few watches that cannot be used for development. When is Apple going to address this glaring bug people have been reporting and talking about in the forums for almost a year with versions of watchos from as early as 9.x and iOS 16?
