问题
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:


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

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.

I think this is architecture of new Apple Watch. It is not architecture of your main app so you can't see it in build settings of your app. For sure it is impossible to submit app from Xcode beta.
I have the same issue but from Xcode 6.2 (not beta). May be itunesconnect does't support watchkit extensions yet.
