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!

Our app is pushed to supervised iPhones through our MDM. We have a watchOS companion app that we install to paired Apple Watches as well. Our watches are NOT enrolled in the MDM using the new watchOS 10 MDM features, and are just paired normally to the supervised phones. Historically (the past 2 years), the watchOS companion app has been installed automatically after our iOS app has been pushed by our MDM (through VPP) and the Watch has been paired. NEW IN iOS 17.4/watchOS 10.4, the watchOS companion app is NOT installed automatically and when we press “Install” in the Watch app on the iPhone, we see a spinner for about 1 second and then a silent failure, with the button reverting back to “Install”. This is occurring with other apps purchased through VPP. We purchased the CityMapper app through VPP, assigned it to a supervised iPhone, and attempted to install CityMapper's watchOS companion app and got the same failed result. This is NOT occurring on a clean & reset supervised iPhone and its paired watch running iOS 17.3.1 / watchOS 10.3. On a personal unsupervised device running iOS 17.4/watchOS 10.4 with a copy of our app purchased through the App Store, installing the watchOS companion app is not an issue. I filed radar FB13687404 but in 10 years of developing for iOS, I have never ever ever heard of Apple responding to one of those. Posting here in the hope that other users/developers can share their issues or solutions.

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."

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?

There is a app I’m trying to download on my watch (watchos only app) and it’s not downloading it’s just loading only and it keeps loading until the install button shows up again hours later

Hey there, I'm implementing Watch Complications in an existing project, and I'm having the problem that transferCurrentComplicationUserInfo(_:) works exactly as transferUserInfo(_:) is described in the documentation, but not as it should. That is, when the WatchApp is opened, func session(_ session: WCSession, didReceiveUserInfo userInfo: [String: Any] = [:]) receives the data sent by transferCurrentComplicationUserInfo(_:). If not, the data is queued until the Watch App is opened again. In other words, transferCurrentComplicationUserInfo(_:) never wakes up the ExtensionDelegate when the Watch App is not running. Has anyone experienced the same thing and know how to fix it? More details: Testing on iPhone 11 (iOS 17.1.2) and Apple Watch SE (WatchOS 10.2) I made sure that the quota of 50 is not exhausted when I test. The WatchApp is still dual-target (I want to avoid having to migrate to single-target and SwiftUI lifecycle) Watch App code: class ExtensionDelegate: NSObject, WKExtensionDelegate, WCSessionDelegate { let session = WCSession.default override init() { super.init() if WCSession.isSupported() { session.delegate = self session.activate() } } func session(_ session: WCSession, didReceiveUserInfo userInfo: [String: Any] = [:]) { WatchWidgetSessionHandler.shared.processComplicationUserInfo(userInfo) } } IOS App code: class WatchAppDataManager: NSObject, WCSessionDelegate { override init() { super.init() let session = WCSession.default session.delegate = self session.activate() } func sendDataToWidget(for kinds: [WatchWidgetKind]) async { guard WCSession.default.activationState == .activated, WCSession.default.isComplicationEnabled else { return } let widgetsData = dataProvider.getData(for: kinds) if !widgetsData.isEmpty { WCSession.default.transferCurrentComplicationUserInfo(widgetsData) } } }

As per iOS SMS sending API, there is no option to send SMS programmatically without user consent. Developer needs to use the MessageUI framework to get iPhone user consent for sending SMS. In that case, if any third party SmartWatch connected through BLE with iPhone received SMS notification through ANCS and want to reply to that SMS, After typing and sending from Watch, user needs to perform this additional step in iPhone - give consent. But if we use Apple watch, this consent in iPhone is not required if Apple Watch is already paired with iPhone. After typing text in Apple Watch, can send SMS to receiver through utilizing iPhone's SMS service without any user interaction. What is the reason of this difference? For sending SMS, iPhone and Apple Watch needs to be paired. Similarly, even third party SmartWatch also performs BLE connection and pair together before sending SMS text from Watch to iPhone to forward to receiver. But in that case why another additional user consent is required in iPhone? If we consider iPhone and Apple Watch case, pairing with each other is considered as user consent for sending any SMS later from Watch utilizing iPhone. Then, why BLE pairing between iPhone and other third party Watch not considered as user consent and additional user consent is required for each time SMS sending?

My requirement is to execute this shortcut on the Apple Watch, where I input speech, and it's converted into text to be saved in the memo app. However, the shortcut doesn't function correctly on the Apple Watch, and I can't sync the content to the memo app. Suspecting an issue with synchronization, I added the current time along with my voice input, only to find that while the current time gets transferred, the text does not. I wondered if the problem was with voice input, so I tried switching to keyboard input, but the outcome remained unchanged. I have tested this issue on multiple Apple Watches and found the problem persists across all devices. Both my phone and iWatch are updated to the latest system versions. https://www.icloud.com/shortcuts/d58d14627dbe450ead5e9217e1a68c27

I’m working on an independent watchOS app which is primarily designed to to collect and periodically send location updates to a server. The UI features a toggle that allows the user to turn this capability on or off at their discretion. The typical use case scenario would be for the user to turn the toggle on in the morning, put the app in the background and then go about their day. Given the limitations and restrictions regarding background execution on watchOS, in an ideal situation, I would be able to upload the stored location updates about every 15-20 minutes. With an active complication on the watch face, it’s my understanding that this should be possible. I’ve implemented background app refresh and indeed, I do see this reliably being triggered every 15-20 minutes or so. In my handle(_:) method, I process the WKApplicationRefreshBackgroundTask like this: func handle(_ backgroundTasks: Set&lt;WKRefreshBackgroundTask&gt;) { backgroundTasks.forEach { task in switch task { case let appRefreshBackgroundTask as WKApplicationRefreshBackgroundTask: // start background URL session to upload data; watchOS will perform the request in a separate process so that it will continue to run even if our app gets // terminated; when the system is done transferring data, it will call this method again and backgroundTasks will contain an instance of // WKURLSessionRefreshBackgroundTask which will be processed below startBackgroundURLSessionUploadTask() scheduleNextBackgroundAppRefresh() appRefreshBackgroundTask.setTaskCompletedWithSnapshot(false) case let urlSessionTask as WKURLSessionRefreshBackgroundTask: // add urlSessionTask to the pendingURLSessionRefreshBackgroundTasks array so we keep a reference to it; when the system completes the upload and // informs us via a URL session delegate method callback, then we will retrieve urlSessionTask from the pendingURLSessionRefreshBackgroundTasks array // and call .setTaskCompletedWithSnapshot(_:) on it pendingURLSessionRefreshBackgroundTasks.append(urlSessionTask) // create another background URL session using the background task’s sessionIdentifier and specify our extension as the session’s delegate; using the same // identifier to create a second URL session allows the system to connect the session to the upload that it performed for us in another process let configuration = URLSessionConfiguration.background(withIdentifier: urlSessionTask.sessionIdentifier) let _ = URLSession(configuration: configuration, delegate: self, delegateQueue: nil) default: task.setTaskCompletedWithSnapshot(false) } } } And here is how I'm creating and starting the background URL session upload task: func startBackgroundURLSessionUploadTask() { // 1. check to see that we have locations to report; otherwise, just return // 2. serialize the locations into a temporary file // 3. create the background upload task let configuration = URLSessionConfiguration.background(withIdentifier: Constants.backgroundUploadIdentifier) configuration.isDiscretionary = false configuration.sessionSendsLaunchEvents = true let backgroundUrlSession = URLSession(configuration: configuration, delegate: self, delegateQueue: nil) let request: URLRequest = createURLRequest() // this is a POST request let backgroundUrlSessionUploadTask = backgroundUrlSession.uploadTask(with: request, fromFile: tempFileUrl) backgroundUrlSessionUploadTask.countOfBytesClientExpectsToSend = Int64(serializedData.count) // on average, this is ~1.5 KB backgroundUrlSessionUploadTask.countOfBytesClientExpectsToReceive = Int64(50) // approximate size of server response backgroundUrlSessionUploadTask.resume() } Note that I'm not setting the .earliestBeginDate property on the backgroundUrlSessionUploadTask because I'd like the upload to start as soon as possible without any delay. Also, this same class (my WatchKit application delegate) conforms to URLSessionTaskDelegate and I have implemented urlSession(_:task:didSendBodyData:totalBytesSent:totalBytesExpectedToSend:) and urlSession(_:task:didCompleteWithError:). In my testing (on an actual Apple Watch Ultra running watchOS 9.3.1), I've observed that when the system performs the background app refresh, I always receive a callback to myhandle(_:) method. But when I start the background URL session upload task (in startBackgroundURLSessionUploadTask()), I was expecting that when the upload completes, I'd receive another call to myhandle(_:) method with an instance of WKURLSessionRefreshBackgroundTask but this doesn't seem to happen consistently. Sometimes I do see it but other times, I don't and when I don't, the data doesn't seem to be getting uploaded. On a side note, most of the time, startBackgroundURLSessionUploadTask() gets called as a result of my code handling a background app refresh task. But when the user turns off the toggle in the UI and I stop the location updates, I need to report any stored locations at that time and so I call startBackgroundURLSessionUploadTask() to do that. In that specific case, the upload seems to work 100% of the time but I definitely don't see a callback to my handle(_:) method when this occurs. Am I wrong in expecting that I should always be getting a callback to handle(_:) when a background URL session upload task completes? If so, under what circumstances should this occur? Thanks very much!

Upgrade phone, then watch was paired to the new phone with developer mode enabled, but developer mode on watch is no longer visible on watchOS 10.4

Hi everyone, We have a sports app that helps track your game scores. Still, when you are in the middle of a game and receive a notification (e.g., an activity notification, a WhatsApp or third-party app), that notification will pop up on the screen, overlapping the app. This forces you to scroll all the way down the notification and close it before you can continue using the app. Some users are complaining about this, and it's indeed very annoying. I was wondering if there's any way to control that during matches, no notifications pop up on your screen (it's ok to have the red dot on top, but having the notification overlapping is what kills the app's usability). Users can avoid this by choosing the right "focus" mode before starting a new match. However, many don't even know this feature exists or how to deal with it. Is there any way to block incoming notifications from appearing on the screen while the app is being executed?

Hello Do we have access to the ECG raw data on the apple watch? I was able to access the data using HKElectrocardiogram Class API. "ecgSample" returns all the recorded ECG logs done by the user using the default apple app. I want to access the data in real-time, do the API supports that? That is, I want to create a custom app in which I direct the user towards recording an ecg signal and then do whatever I want with it. Please let me know, that would be very helpful!
