When I try push my app to review I got:
Applications must be ready for upload on iTunes Connect before they can be validated or submitted from within Xcode.
What mean by ready for upload on iTunes Connect?

You need to go into iTunesConnect and start filling out the information for your app. It will tell you when its ready for the actual upload.
in my case I tried to upload binary to wrong developer account.
