XCode 8 GM Seed - Error while uploading to TestFlight

Question

While Uploading the .ipa file (Generated using Xcode GM Seed) into TestFlight, I am receiving the following error.

ERROR ITMS-90596: "Invalid Bundle. The asset catalog at 'Payload/Application.app/Assets.car' can't be read. Try rebuilding the app with a non-beta version of Xcode and submit it again."

DBG-X: The error code is: 1102

Did anyone get across similar issue?

Answer 1

1) Double check and make sure you are building with Xcode 8 GM Seed.
2) Make sure you are using latest version of El Cap.
3) Delete ~/Library/Developer/Xcode/DerivedData folder.(It was my issue)
4) Rebuild project.
Make sure environment you are submitting from is also running Latest El Cap and Xcode 8 GM.

If you working with multiple version of Xcode (i.e. 7.3.1 & 8.0 or higher), make sure you launch Application Loader from respective Xcode version. If you build an IPA file from Xcode 8.0, open Application loader from that Xcode -> Open Developer Tool -> Application Loader.

Good luck!

I had this warning just now and it turned out to be completely false - the actual issue was that I was using Application Loader v3.5 to submit an application that had been written in Xcode 8. So if nothing else works, ensure that you either use the Archive screen to upload your build from the version of Xcode upon which the archive was created, or else open Application Loader from the correct version of Xcode by selecting Xcode > Open Developer Tool > Application Loader
