Button("Sign In", action: signIn)

Cannot find type

Don't you remember what I wrote before?

Ignore the word scope in the error message and find what you need to define.

When you get an error message like Cannot find 'signIn', it is signIn that you need to define, not Button.

But your code currently shown does not make sense.

Line 27...29: Text are not appropriate for WindowGroup
Line 47: You cannot write Button at the toplevel of the code
Line 51...59: Button is a predefined type in SwiftUI, it is not what you need to define
