Answer 1

Install Xcode 8: https://developer.apple.com/download/

Xcode 8 GM seed may be used to submit apps to the App Store.

More info: In my case I updated to the latest Facebook iOS SDK 4.15.1. Since that library was updated with Xcode 8 and I was still using Xcode 7.3.1 it caused the error.

Updated for Xcode 8 GM and iOS 10.

So, double check 3rd party libraries.

Or if you don't mind disabling bitcode: Go to build settings search bitcode and change "Enable Bitcode" to "No".
