After updating to iOS 17.5 & WatchOS 10.5, the didFinish response from WCSessionDelegate does not come when transferring files from iPhone to Watch. It worked normally until 17.4 & 10.4. There is no problem with checking file completion even if a didFinish response is not received, but I think Apple needs to check this issue and update. File transfer is done using the transferFile function of WCSession. The file being transferred is a single file and its size does not exceed 30MB. When you try to transfer Pi, the message below appears in the Xcode log section. -[WCFileStorage persistOutgoingFileTransfer:] error serializing file transfer <WCSessionFileTransfer: 0x300155d60, session file: <WCSessionFile: 0x3001575c0, identifier: 0C8857EC-7D74-4E78-BA28-6C5526DE8949, file: /private/var/mobile/Containers/Data/Application/DD797847-DED1-42C0-989F-34CD05825007/tmp/C042D096-F12B-4B50-8792-868475DBBF47.zip, hasMetadata: YES>, transferring: YES> due to Error Domain=NSCocoaErrorDomain Code=4866 "Caught exception during archival: This object may only be encoded by an NSXPCCoder.

As TN3135 clearly explains the limitations apple puts on the low level networking, it doesn’t really give a reason. Presumably the power consumption problem. But as the battery technology continues evolving, it could be exciting that apple might loose the restrictions someday. The watch itself is powerful enough to do a lot of sophisticated works, sure it works best with companion apps on iPhone, but even as a standalone device, we can still provide many advanced user experience with low level networking supports. wish apple guys can read it and give a consideration.

Criticism of the use of the Minimed Mobile App, problem with the update interval of the Apple Watch iOS Subject: Error event - Minimed Mobile App . Triggered by insufficient update interval of the Watch iOS system of only 50 updates/day Dear Sir or Madam, I use the Minimed Mobile App in conjunction with my Medtronic 780 G insulin pump and am generally very satisfied with the app. However, I have noticed a point here that is caused by the Apple Watch iOS operating system. I would like to pass this on and ask that you please fix this problem with an update. Updating the sensor values on watch faces on the Apple Watch I use the Modular widget on my Apple Watch in conjunction with the Minimed mobile app to quickly and easily keep an eye on the current sensor value. Unfortunately, the sensor value in this widget is not updated automatically according to someone in the know, Apple only updates widget information 50 times a day. After a short time, a rotating arrow appears instead of the current value, which I have to press to get a sensor value displayed again in order to see the current value. This is very inconvenient as I have to perform several actions each time to see the current value: 1.Open widget 2.Press the rotary arrow 3.Read the value Close widget by pressing the spin button at the top right to return to the main screen I would very much welcome it if the sensor value in Apple Watch watch faces were updated automatically, the problem is obvious - the watch faces only update 50 times a day. This would prevent me from seeing the current sensor value quickly and easily at any time without having to perform additional and cumbersome actions. The Minimed Mobile App has been tested and approved by Medtronic through Apple. However, it must have been overlooked that this sensor value app updates the sensor value every 5 minutes, but it does not do this on the dial because, according to my friend, it only updates 50 times a day. Now it is the case that the sensor value can change every 5 minutes, but this is not shown on the watch face, which means that the Apple Watch iOS would need 288 updates for this Minimed Mobile App per day instead of only 50 updates per day. Can you please advocate for a new update that allows an update interval of up to 288 updates per day? So that thousands of diabetics worldwide can see current values on their Apple Watch dials at any time? Without having to take several steps each time? I switched to I Phone and Apple Watch because I thought this would be possible for me. I would be very happy to hear back if this is technically possible for all diabetics worldwide who will benefit from it. With kind regards

Hi, I would like to stream live audio (hls) from watch itself, our app can start stream on paired device, but when phone is not near by i want to start streaming on watchos (just like spotify or Apple music app) I watched the 2019 wwdc video about streaming and also looked to the documentation Documentation : https://developer.apple.com/documentation/watchkit/storyboard_support/playing_background_audio I can present the route controller to select output, but for example after selecting Air Podcas, stream did not start.. Here is the code: (I have enabled background mode audio) do { try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default, policy: .longFormAudio, options: []) } catch { print("no audiosession!") } AVAudioSession.sharedInstance().activate(options: []) { success, error in dump(success) dump(error) DispatchQueue.main.async { if let streamURL = moduleItem.media?[0] as? String { dump(streamURL) let asset = AVURLAsset(url: URL(string: streamURL)!, options: nil) let item = AVPlayerItem(asset: asset) let player = AVQueuePlayer(playerItem: item) player.play() } } }

I am trying to develop a watch app and got all the plumbing in place. I successfully send messages from the phone to the watch and see updates reflected in the UI. However when I connect to a device that streams data over bluetooth, using the same messaging interface the data fails to transfer. It appears WCSession.default.isReachable becomes false as soon as this BLE stream starts. I suspect the app is prioritizing the BLE radio for this instead of connectivity to the watch? Is my assumption valid? Are there any workaround to this?

Despite the iPhone 11 running iOS version 17.4.1 and the Apple Watch Series 3 operating on version 8.8.1, and both devices being connected, the Apple Watch remains undetected within Xcode version 15.3.

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) } } } Thank for your answers !

AFAIK, background execution with Background Tasks framework is all budgeted. E.g., if we try to use it too much, the system would simply stop letting us do it, at least for some time. Is it the same when we do sendMessage from Watch app to iOS app? Is there a chance we may overuse it so that system stops waking up the iOS app? Or I can rely and use sendMessage as often and heavy as I need?

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?

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?

Since I installed iOS 17.4.1, my Apple Watch Series 1 no longer shows the media that is playing on my iPhone or Apple TV. Does anyone know anything about it?

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.

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."

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?

I am working on an application design where I would like to have the Iphone running an app such as Apple Map, and while I might be driving in the car I would like to have my apple Watch invoke a screen shot of the current view of I map showing my location without having to use the iphone. So the Iphone would be active and in a car holder displaying my location on the map. Once I made my route point, such as a waypoint. I would like to press a button on my watch app to do a screen print. Second though is, could I press a button on my Apple Watch app to fire an request to my own IOS Application using WatchConnectivity to capture my Location to a data file. Third thought is could a press a button on my Apple Watch app to interact with an active app, which is an app like a reminder app and create a new Reminder Note in the active app in focus on my Iphone, but is not a component of my IPhone App. Thanks for any insight how I could make a Apple Watch app send Button Presses reliably to my Iphone Application active, so that I. could avoid having to touch my iPhone? Thanks in advance for any guidance.

我正在开发一个即时通讯的App，遇到个问题，就是如何做到跟微信一样，iPhone上收到语音通话邀请通知时，配对的watch上持续响铃？

I have a watch companion app that sends several message to the iPhone and the phone replies with the data the watch needs. This works perfectly on the simulator and when I deploy directly from XCode to my phone/watch. However, when deployed to test flight the watch never receives replies from the phone. I've added logging and WCSession is active, WCSession.isSupported is true and WCSession.isReachable is true. The watch just doesn't receive a reply from the phone. Is there something I have to put in the Plist to make this work in Test Flight? Has anyone ever had a similar problem?

There's another thread on here with similar Q but seems to have no resolution. So starting my own. The basics Xcode 15.3.0 beta 3 iOS 17.4 The WatchOS 10.4 I have an iPhone app with a companion watch app. In Xcode if I set the scheme to my iOS app it installs on my phone but the companion watch app does not auto install on my watch. Automatic App Install is turned on in Watch app on iPhone. To run the app on watchOS I have to run it directly from the watch scheme on Xcode. If I delete the app from the watch then go into the iOS watch app on the iOS device to install on my watch I receive an error "This app could not be installed at this time" Is there a known cause solution?
