Any update yet on this? Am still able to upload and submit, just not sure why this error message, and I am running 8.3.2 as well…
Dear developer,
We have discovered one or more issues with your recent delivery for “Touch The Crack”. Your delivery was successful, but you may wish to correct the following issues in your next delivery:
Deprecated Xcode Build - Due to resolved app archives issues, we will be deprecating Xcode 8.3 on May 10, 2017, at which time app archives built with 8.3 will no longer be accepted by the App Store. Download Xcode 8.3.2 or newer, rebuild your app and resubmit.
After you’ve corrected the issues, you can use Xcode or Application Loader to upload a new binary to iTunes Connect.
Regards,
The App Store team
