Question

I’ve been submitting my app to the App Store for test flight and after build 11, I’ve been getting failures via email from Apple:

Answer 1

After a LOT of investigations on this part we finally found the problem for this issue: It seems like Apple gives this error for applications that suport both 32 and 64 bits.

Apple gave this reminder for Mac Appstore, but it seems that iOS applications are affected as well.

So a solution for this is to support bitcode OR to drop support for 32 bit devices by removing support for ARMV7 and ARMV7S or bellow from Valid Architectures from build settings. This will mean your application will work only on iPhone 5S and above. I hope this helps someone. Thank you!
