I want to change the configuration of the screen in iOS sdk version.

The general method can be solved in this way.

@ViewBuilder
    func PermissionItemView(_ icon: String, _ title:String, _ text: String) -> some View {
        if #available(iOS 15, *) {
            HStack {
            }
            .listRowSeparator(.hidden)
        }
        else {
            HStack {
            }
        }
    }

However, to reduce the weight of the program code,

I want to do the same as the Define Macro in C++.

@ViewBuilder
    func PermissionItemView(_ icon: String, _ title:String, _ text: String) -> some View {
        HStack {
        }
        if #available(iOS 15, *) {
            .listRowSeparator(.hidden)
        }
    }

Is there a way?
