Hi, I am trying to upload my app to TestFlight, I have successfully using unity and Xcode built and transferred to my iPhone and all works fine. In order to use test fight to distribute for testing I need to Create an archive from within Xcode then upload to App Store connect, The archive fails in Xcode with the errors shown in the screen grab
I am using the latest trial Unity SDK, unity version 2019.3.0f6, Xcode 11.3.1
I have the exact same scenario!
I resolved this issue by setting the architecture to ARM64 in the Player settings/Other settings/Configuration/Architecture.
