SwiftUI Argument passed to call that takes no arguments

Error : Argument passed to call that takes no arguments

Explanation : I have 2 different views, ContentView and MainView. There is a @Binding variable in MainView which is @Binding var showMenu: Bool. When I try to call MainView with the an argument, I get the error specified above.

Code Snippets :

struct ContentView: View {
@State var showMenu = false
var body: some View {
    GeometryReader { geometry in
        MainView(showMenu: $showMenu)
            .frame(width: geometry.size.width, height: geometry.size.height)
            .offset(x: self.showMenu ? geometry.size.width/2 : 0)
            .disabled(self.showMenu ? true : false)
        }
    }
}

and

struct MainView: View {
@Binding var showMenu: Bool
//unrelated variable declarations
init() {
    //unrelated code
}
var body: some View {
    //unrelated code
}

The problem is this line:

init() {
    //unrelated code
}

When you said that, you said that the only to make a MainView is by saying MainView(). So it is indeed true that you now can't say MainView(showMenu:...).

You have three main choices that I can see:

  • Delete the whole init().

  • Replace the whole init() with something like this:

    init(showMenu: Binding<Bool>) {
    self._showMenu = showMenu
    // other stuff?
}

  • Rethink the architecture. (We'd need to see more of what this binding is for.)
