How to CodeSign for upload to iTunesConnect [closed]

Question

It has been a few months since I have code signed an app and I can't remember exactly what do I need to do?
Everything is 100% ready except this

Answer 1

1. Read all the docs that other users suggested you to (re)read.
2. Update/create provision profile for distribution, set status of app in iTunesConnect Waiting for upload.
3. Sign your application in Xcode with this profile
4. Select iOS Device
5. Product->Archive
6. If build was successfully ended then Organizer will open. Submit your application.

Answer 2

Here are two apple docs that you should (re)read from Apple's iOS Development Guide:
