SwiftUI preview provider with binding variables

Question

How do I generate a preview provider for a view which has a binding property?

struct AddContainer: View {     @Binding var isShowingAddContainer: Bool     var body: some View {         Button(action: {                 self.isShowingAddContainer = false             }) {                 Text("Pop")             }     } }  struct AddContainer_Previews: PreviewProvider {     static var previews: some View {         // ERROR HERE <<<-----         AddContainer(isShowingAddContainer: Binding<Bool>()     } } 

In Code above, How to pass a Binding<Bool> property in an initialiser of a view?

Answer 1

Just create a local static var, mark it as @State and pass it as a Binding $

struct AddContainer_Previews: PreviewProvider {   @State static var isShowing = false   static var previews: some View {     AddContainer(isShowingAddContainer: $isShowing)   } } 

Answer 2

Other way

    struct AddContainer_Previews: PreviewProvider {       static var previews: some View {         AddContainer(isShowingAddContainer: .constant(false))       }     }
