SwiftUI Mac OSX SearchBar element - swift

Question

I am currently developing a app in SwiftUI for MacOSX. I am having a custom List View with many rows. I want a SearchBar to filter my rows.
Coming from Objective C, I know there was a SearchBar and SearchBar Controller. I just would need a SearchBar with the default Mac OS X Search Bar design. However, I didn't found anything.
There was a answer on Stackoverflow, which dealted with the same problem but for iOS. But that is not convertible to Mac OS X.
Currently I am using a regular TextField and wrote my own filter script, which worked fine. However, I want to SearchField UI as Apple uses it. Is that possible?
Is there any chance to use AppKit to achieve that?
That's what I want to achieve:

Answer 1

Your best bet is to wrap an NSSearchField in an NSViewRepresentable.

Answer 2

Here is my solution that I am now using:
struct FirstResponderNSSearchFieldRepresentable: NSViewControllerRepresentable {
#Binding var text: String
func makeNSViewController(
context: NSViewControllerRepresentableContext<FirstResponderNSSearchFieldRepresentable>
) -> FirstResponderNSSearchFieldController {
return FirstResponderNSSearchFieldController(text: $text)
}
func updateNSViewController(
_ nsViewController: FirstResponderNSSearchFieldController,
context: NSViewControllerRepresentableContext<FirstResponderNSSearchFieldRepresentable>
) {
}
}
And here the NSViewController
class FirstResponderNSSearchFieldController: NSViewController {
#Binding var text: String
var isFirstResponder : Bool = true
init(text: Binding<String>, isFirstResponder : Bool = true) {
self._text = text
super.init(nibName: nil, bundle: nil)
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func loadView() {
let searchField = NSSearchField()
searchField.delegate = self
self.view = searchField
}
override func viewDidAppear() {
self.view.window?.makeFirstResponder(self.view)
}
}
extension FirstResponderNSSearchFieldController: NSSearchFieldDelegate {
func controlTextDidChange(_ obj: Notification) {
if let textField = obj.object as? NSTextField {
self.text = textField.stringValue
}
}
}
