Convert String to Binding<String> in Swift

Question

Most of the solutions I see are partaining to SwiftUI where a string can be passed as a Binding String like this

TextField("", $text)

But in this case, it's purely on Swift... I have this code below

final class Coordinator: NSObject, UITextViewDelegate {
    var text: Binding<String>

    init(text: Binding<String>) {
        self.text = text
    }
    
    func myFunc(){
        let string = "my string" // a dynamically created String
        self.text = string // This throws an error that I cannot assign value type of string to Binding<String>
    }
}

How can I get to convert String to Binding<String> ?

Answer 1

The name Coordinator suggests that we are talking about UIViewRepresentable .

If so the usual way is to declare the Binding in the UIViewRepresentable struct and pass the MyView instance to the coordinator to have access to it

struct MyView: UIViewRepresentable
{
    @Binding var text: String
    
    func makeCoordinator() -> Coordinator {
        return Coordinator(self)
    }
...

final class Coordinator: NSObject, UITextViewDelegate {
    var parent: MyView

    init(_ parent: MyView) {
        self.parent = parent
    }
    
    func myFunc(){
        let string = "my string" // a dynamically created String
        parent.text = string
    }
}
