How to assign an optional Binding parameter in SwiftUI?

Question

I\'m trying to build a custom NavBar with some optional Views, like a searchbar (but only if the view needs to display it).

I need to pass

Answer 1

I have a UIViewControllerRepresentable in order to use UIImagePickerController. If you've ever used this image picker, you know that you need to image returned to be an optional. So in my ContentView I declared:

@State var uiImage: UIImage?

...

if uiImage != nil {
    Image(uiImage: $uiImage
} else {
    Rectangle()
}

And in my ImagePicker (that's my SwiftUI view) I have:

@Binding var uiImage: UIImage?

Works like a charm.

(The if statement is pretty much psuedo-code, as I'm actually using an MTKView and a CIImage, but your get the drift - you use the optional just as you would anywhere else.)
