iOS Testflight “There was an error loading your builds.”

Question

Over the last few days I\'ve tried to set up test flight for my iOS application through iTunes connect, however, whenever, I try to switch on TestFlight, I get an error saying \

Answer 1

This just happened to me. I submitted several builds to App Store/Test Flight without issue. Then I submitted a build with bitcode turned off. It took much longer than usual to process the build (six hours, whereas it usually takes around ten minutes), and then it was marked as failed. I tried again and the same thing happened.

Submitting the app again with bitcode turned on worked.

It seems like bitcode isn't "optional", after all, as Apple would have us believe.
