SwiftUI Views with a custom init

Question

Let's say that I am making a custom input element that looks like this:

struct CustomInput : View {     @Binding var text: String     var name: String      var body: some View {         TextField(name, text: $text)             .modifier(InputModifier())      } } 

Currently, when I instantiate this view I'm required to pass both text and name names to arguments. I want to be able to make the name argument optional, like in the example below.

 CustomInput("Some name", $text) 

Typically I'd use an init method for this. But I'm not sure how to handle property wrappers like @Binding in the init function.

Any ideas on how I can achieve this?

You can write your initializer like this:

struct CustomInput : View {     @Binding var text: String     var name: String      init(_ name: String, _ text: Binding<String>) {         self.name = name          // Beta 3         // self.$text = text          // Beta 4         self._text = text     }      var body: some View {         TextField(name, text: $text)     } }
