Cannot assign value of type 'Binding<String>' to type 'String'

I get the following error:

Cannot assign value of type 'Binding' to type 'String'

How to fix it? Please help.

struct TextFieldWithClear: View {
    var title: String
    @Binding var text: String
    
    init(_ title: String, text: Binding<String>) {
        self.title = title
        self.text = $text // ERROR: Cannot assign value of type 'Binding<String>' to type 'String'
    }
    
    var body: some View {
        HStack {
            TextField("Title", text: $text)
            Image(systemName: "xmark.circle.fill")
                .onTapGesture { text = "" }
        }
    }
}

Replace:

self.text = $text

with:

self._text = text

You need to inject the value of text into the wrapped value of self.text. The underscore "opens" the Binding for you to change its wrapped value. Don't need to use $ in your initializer.
