1. Compile your App ( Build Release App )
2. Download Release App ( you have in your folder file ZIP with all necessary files)
3. Upload App To iTunes Connect
In most cases this error happens when you don't compile in release mode with a store provision profile. Pay attention to the compilation window text. It tells you whether it is a store compilation.
It is not enough. Compile again and check the compilation window text. If it doesn't say that it is a store build then you are not using the correct provision profile.
