Question

I want to upload build with Custom keyboard extension on Itunes Connect But when I am going to upload it on Itunes Connect through Application loader its show me following error

Answer 1

Please check your embedded frameworks, if any. I've faced the same issue and the reason was: While debugging app on device, Xcode builds frameworks for "current arch only". And then, even if you try to archive project, Xcode uses already built for only one(!) arch frameworks from debug-iphoneos folder.

So, I've solved this issue by setting flag "Build for current architecture only" to "No" in Build settings of framework targets, cleaning build folder (cmd option shift K), Archive.
