iTunes Reject Binary Upload
When you upload your binary to iTunes after distribution your app in Xcode, you might have found a mistake and want to delete and upload a new binary. This is possible in iTunes.
iTunes Connect -> Manage Your Applications -> Select the App -> View Details
Under Links select Binary Details and press “Reject This Binary”
Now it’ll ask if you’re sure.
Reject This Binary. Are you sure you want to reject this binary? If you reject this binary, it will be removed from the queue and it will not be reviewed. To resubmit it, you will need to prepare a new upload.
Noted that although you can do this it will put your app at the back of the line in terms of app store approval.
