This code with optional Binding and TextField crashes:

struct ContentView: View {
    @State var optionalText: String?
    
    var body: some View {
        
        Button(optionalText == nil ? "Show" : "Hide") {
            optionalText = optionalText == nil ? "Text" : nil
        }
        if let $text = Binding($optionalText) {
            TextField("", text: $text)
        }
    }
}
This workaround thanks to @iampatbrown prevents the crash:

TextField("", text: $text)
    .transition(.identity) // workaround thanks to @iampatbrown
So it seems the crash is related to animation. It seems FB8367784 - a crash with optional Binding and Toggle was reported before and fixed. Hopefully it can be fixed for TextField too, and all the other controls that take bindings.
