After archiving in Xcode 12.3 my archiving is getting succeeded but while validating I am getting these two errors
App Store Connect Operation Error Missing architecture. Apps built with Watch OS 5.0 and later SDKs must contain additional architectures.
App Store Connect Operation Error Invalid Code Signature Identifier. The identifier "com.apple.WK" in your code signature for "AppName Watch " must match its Bundle Identifier "bundle identifier"
