New iTunes connect interface error "You must choose a build"

Question

When trying to submit my new app to the app store, I noticed Apple has changed its website interface: after updating metadata and keywords and hitting "submit for review" I got the error "you must choose a build".

By looking into google I found no answer.

However, I noticed that there is a plus button next to the 'build' heading where you have to select a build. This button is hidden somehow similarly to game center where achievements can't be deleted just because of the padding which hides the delete button.

So anybody have any ideas or solution to this. Please help

Answer 1

You have to upload a binary for your new App. Then, you wait ~5-20 min while processing and select the plus button and select a binary and save. After that you may Submit for Review. If it takes longer than ~25 min try uploading the binary again.

Answer 2

I uploaded a binary and still I cannot choose it.

When I clicked on Prerelease I could see that the binary is listed and when I pointed to the ? it says

After builds are uploaded they will go through a processing status before they can be used.

So I guess Apple has introduced a new step into the process, and we must wait for it to complete.
