I have an iPhone & iPad app that does not contain an Apple Watch app. When the app receives a push notifications, and my phone is locked, I receive the notification on my Apple Watch. However, the image in the notification is missing: When I swipe down on the watch, the image is also missing on the received notification. On the phone, the icon displays correctly. My watch is a Series 5 (44mm) A2095. Below is all the icons present in my asset catalog. Please help!

Hello, Im developing an application in health care topic. Im currently using Python + AWS for backend and react native for frontend. I would like to implement the connectivity with apple watches to gather information about day rhythm, heart rate etc. Is there any solution to gather those information automaticly using some type of scripts without exporting the csv files? I would like to have a simple interface to work with the data.

This is really getting my goat. What a 10-year old could do with a breeze, the most advanced technologists couldn't. How can the average be greater than the greatest of individual entries? I posted this on a couple of occasions in twitter tagging your support team. But, apparently you people haven't bothered to look at it or swept it under the carpet.

Hello, I have a gen 2 Apple Watch that I’m trying to pair with my iPhone XR. The Watch has been reset to factory settings, and whenever I try to pair them it says I need a update but it won’t because it says I’m not connected to the internet. I have tried everything at this point, it’s connected to the internet, I have the current 15.5 update on my phone, and tried redownloading the app.

So I recently tried to update my watch. I have an iPhone X iOS 14 and a series 3 watch without cellular. At first it couldn’t download because it didn’t have enough space. I don’t have many apps if any on my watch, so I tried restarting it because I read in another help guide to do that. After I did that, the watch reverted to factory setting and there was no way for me to download the new update because I’m not “connected to the internet” despite having great service and WiFi. The app doesn’t let me use the watch without updating it of course, so now my beloved watch is now an expensive paper weight. Other websites load on my phone so the internet isn’t the problem. I’ve tried resetting everything and resetting the network settings and turning off cellular for the watch app and I can’t access anything on the watch and can’t access settings on the watch app because it only tells me to pair a watch. Please please help.

To whom this may concern, I am writing as I have several questions regarding your PPG sensors and in particular your API as I would like to use your HRV data for research purposes. Do the PPG sensors found within your device take readings 24 7 and at what refresh rate i.e. 50Hz?  If so, then would I be able to retrieve this data from your cloud database If not then can I, upon the users request, override this protocol via the API to make sure that the PPG sensor is operating constantly What file format does the data come in and what exact metrics are contained within the file i.e. IBI, sdnn, rmssd? I look forward to your response. Best regards,

Hi, My middle schooler is working on a project for National Science Fair competition to estimate blood pressure from ppg signals. While he is using external database to develop his algorithm, it would be very useful to test it with real time data. I have a Series 6 watch and wondering how I can access my ppg sensor raw data.

When I finish Running on AppleWatch, I can see the value of average cadence on Apple Watch's Workout App and iPhone's Fitness App, but I can't find any APIs about that value.However I'm not sure how does Fitness App calculated, I tried to get step count from HealthKit, and calculated the value, but the value is different from Apple's. Can you tell me how to get it correctly and accurately?

Hi I am working on the iPhone + Apple Watch development and I am facing this issue a few days in a row. I know how to fix it - unpair and then pair Apple Watch again, but it is not a solution at all. (Yes, I'm certain that my watch is paired) Maybe someone knows how to fix it?

Hi, Xcode 12.5's iPhone simulator silently fails in sending its app context via updateApplicationContext() to the Watch simulator. No exception is thrown, so it appears as if everything is ok - but not really because the WatchOS simulator never gets the app context This works fine on real devices as well as earlier versions of Xcode. Doing a updateApplicationContext() from the WatchOS simulator to the paired iPhone simulator does work. I filed a bug report for this issue, because this behavior has been in Xcode 12.5 since the beta version: FB9095737 (Xcode 12.5 WatchOS Simulator never receives application context from iPhone counterpart) Before anyone says "why not debug on a real device instead?", please be aware that due to the pandemic, while I do test on real devices, I can only debug on a simulator. Thanks

I'm using the following code to get CMMotionActivity updates on iPhone and apple watch, RESPECTIVELY. It works great on iPhone, i.e. motionActivityString keeps getting updated immediately and infinitely. However, when running the same code on apple watch, the string is only updated once rather than continuously. So my question is how to get continuous update on apple watch, just like the iphone does? Thanks! class MyMotionManager { @Published var motionActivityString: String = "" private let activityManager = CMMotionActivityManager() func checkMotionActivityInForeground() { if CMMotionActivityManager.isActivityAvailable() { activityManager.startActivityUpdates(to: OperationQueue.main) { (motionActivity) in guard let activity = motionActivity else {return} print(activity) // The string is updated (almost) immediately and continuously when running on iPhone. // However, it's only updated once when running on watch. if activity.stationary { self.motionActivityString = "Stationary" } else { self.motionActivityString = "Moving" } } } }

Hi, Currently I'm working on Apple Watch ui testing using XCTest and I need to interact with Apple Watch's Home screen in order to perform different actions with complications. As I know from my iOS experience, Home Screen can be by using bundle id "com.apple.springboard". I need something similar but for watchOS.
