We got an error, when we tried to upload new build to itunesconnect via Xcode 8 (from App Store and from http://developer.apple.com/download/more/ — the same behavior). We use Swift 2.3 in our project and some pods.
ERROR ITMS-90596: "Invalid Bundle. The asset catalog at 'Payload/***.app/Assets.car' can't be read. Try rebuilding the app with a non-beta version of Xcode and submit it again."
Any ideas? 😕
