The #Preview macro is frustrating me! Test data that looks obvious to me fails to build. Here is a stripped down example:-

    import SwiftUI

    struct TestView: View {
        @State private var intValue = 0

        var body: some View {
            TestMenuView(intValue: $intValue)
        }
    }

    #Preview {
        TestView()
    }

    struct TestMenuView: View {
        @Binding var intValue: Int

        var body: some View {
            Text("Value passed in was ($intValue)")
        }
    }

    #Preview {
        TestMenuView(intValue: 1)
    }

But the #Preview of TestMenuView gives the error:-
Cannot convert value of type ‘Int’ to expected argument type ‘Binding’
