Xcode unsupported architecture armv7k

Question

When trying to validate my new app using watchkit with xcode 6.2 I get a strange error:

iTunes Store operation failed. Unsupported architectures. Your executable contains unsupported architectures '[armv7k]'.

What does armv7k even mean? All my build settings (for the app and all extensions) look like the ones in the following screenshot: Could the red color of my embedded binaries have something to do with the problem? Everything works great on my device and on the simulators. Thanks in advance!

Update: xCode 6.2 and iOS 8.2 was released. Problem is still there.

Answer 1

It's more than likely not passing validation as you can't actually submit watch apps yet.

Per https://developer.apple.com/watchkit/:

Please Note: Apps built with Xcode 6.2 and iOS 8.2 SDK may be submitted to the App Store. However, WatchKit extensions are not accepted at this time.
