SwiftUI @Binding Initialize

Question

Been playing around with SwiftUI and understood the concept of BindableObjects etc so far (at least I hope I do).

I bumped into a stupid problem I can\

Using Binding.constant(false) is fine but only for static previews. If you actually wanna launch a Live Preview, constant will not behave the same way as the real case as it will never be updated by your actions. I personally use Live Preview a lot, as I can play around with an isolated view.

Here is what I do for previews requiring Binding:

import SwiftUI

struct SomeView: View {
   @Binding var code: String

   var body: some View {
     // some views modifying code binding
   }
}

struct SomeView_Previews: PreviewProvider {
  static var previews: some View {
    PreviewWrapper()
  }

  struct PreviewWrapper: View {
    @State(initialValue: "") var code: String

    var body: some View {
      SomeView(code: $code)
    }
  }
}
