Running the app on a real Apple Watch and infinite spinner

Question

I wanted to make a clickable prototype of an app on (storyboard only). I have just added two interface controllers and some images and buttons. I filled xcassets with several images (overall less than 150kB) and tried to run the app. When there was a single interface controller with 3 buttons (images in background) + 1 imageView (around 100kB all) it took some time but the app lauched. I added 1 more interface controller and a few images to it (the biggest are around 9kB) and this time Xcode displayed me a message that it lost a connection with an iPhone but the watch is still running or the watch app timed out error. At the same time I have the app name on the watch screen and a spinner. And it's spinning for ages without any result... I've tried to delete the app from both devices, restarting, cleaning folders etc. and no success. Is there a limit of images one can put in the watch's xcassets? So frustrating...

You should not use the watch flag but the apple-watch flag. – Boong

Answer 1

I was also facing same issue where spinner on real devices was never ending. This was because watch extension and watch app were missing arm64 architecture, make sure you select Standard Architectures(armv7 and arm64)in build setting.

Answer 2

Here is what you could do/check:

• You should use the xcassets that is located in your WatchKit app, not the one in your WatchKit extension.
• Build and run your main iPhone app as the primary target once.

I use xcassets located in my WatchKit. I haven't checked your second tip but so far I have found a solution which works but is bit annoying. It looks every time I want to make a new build (even if there are little or no changes to the app) I have to: delete the app from both devices, restart both devices, clean & clean build folder and restart xCode... – Eryneryngo

Answer 3

Yeah, i've been struggling with this too...

the only way i found : i click on digital crownd of the AppleWath, then re-tap on my app and magically the app launching (and the debugger work.)

if this is not working the hard way : Reboot xcode, Clean, if still not working same as you clean, restart devices... this is so annoying.

first solution take less time, and work 7/10 times

if someone knows a beter solution i'll take it !! ;-)
