Xcode : How to validate the app in organizer : iOS

This is the first time i am uploading my app in iTunes.

First I made a developer provisioning profile, set the code signing (in build settings) and tested the app in my device.

Then I only made distribution Provisioning profile to upload the app in iTunes and downloaded the provisioning file. I double clicked and I got the the id in code signing under build settings. [NOTE: I did perform any changes in Certificates and Identifiers. Bundle identifier of the app also matches the app id in distribution - provisioning]

I added my app in iTunes connect and shows a yellow dot saying "Prepare for upload"

I build and archived.

When click on distribute and select fist option "Submit to iOS appstore", i get a dialogue box "Applications must be ready for upload on iTunes Connect before they can be validated or submitted from within Xcode."

Which step did I miss?

Solution

The only step you're missing is going to your iTunes Connect page, manage application, click on the app you want to upload and then click "Ready to upload binary"
