Invalid Apple Watch icon file names must match pattern “*@x.png”

Answer 1

it also can be related with the alpha channel (transparency) of your icons. More info: https://developer.apple.com/app-store/watch/

Answer 2

I got the same issue when I tried to submit. My problem was that I was sharing my image asset file with both my iOS app target and my WatchKit app target. You need to have a separate image asset file for your WatchKit app and it should ONLY have images for the Apple Watch in it. That fixed it for me.

Answer 3

I had the same issue. This is how I fixed it:

1) changed my name format to: Icon_24@2x.png

2) Removed files from derived data (I used Watch Dog for XCode for this - https://itunes.apple.com/au/app/watchdog-for-xcode/id734258109?mt=12)

3) Closed and re-opened Xcode

Then my archive validation succeeded. I think the derived data removal was the actual fix, but I changed my icon name format at the same time so cannot be sure if the name change also contributed.

I hope this helps.
