@eskimo Previously Xcode 15.2 we build the SDK and same SDK we were able to use it lower version for building our App say Xcode 15.1 / Xcode 15.0.1.There was no compile time issues .(In build settings as well Swift 5 is the version set) Only now the SDK generated in Xcode 15.3 , when we try to use in Xcode 15.2 we are facing compilation issue as mentioned above.
