Missing Icons error when submitting my Apple Watch App

I get an error when trying to submit my Apple Watch app to iTunes Connect.

The error I get when trying to Archive my App

However, I have added all Apple Watch icons to my xcassets file and have added it to my Apple Watch App Target.

The xcassets setup

So I don't know what to do about this. Thanks!!

Solution

This is a crazy bug on Xcode 6.2 but I found an easy fix (after lots of hard work).

Apparently, Xcode doesn't work well when using same icons for the app and for the watch at the same asset catalog so just separate the icons and that would fix that.

Moreover, Pay attention that the assets resource is attached to the WatchKit app.

Just a small notice, Pay attention to have a square icon and not to include any transparency on those icons. It would be submit if you do but would reject automatically after few minutes.
