Question

Before I start writing about the error, I\'m running on macOS Sierra and using Xcode 7.3.1.

So I\'m creating an Archive from my App, I validate the App and it passes

Answer 1

I accidentally opened an old version of the Application Loader Version 3.5 (921) and got the error ITMS-90167 no app bundles found. Be sure you open the Application Loader over the menu of Xcode (Xcode->Open Developer Tool). Version 3.6 (1020) works like a charm! :)
