SwiftUI Button action not working over GMSMapView - swiftui

Question

I am trying to get my own custom button floating over a GMSMapView. The button draws on the GMSMapView, but the button action is not triggered. The Floating button is written in SwiftUI and this is it:
struct MyLocationView: View {
#ObservedObject var viewController: ViewController
var body: some View {
ZStack {
Button(action: {
print("Hello")
self.viewController.myLocationButtonPressed = !self.viewController.myLocationButtonPressed
}) {
ZStack {
Circle()
.foregroundColor(.black)
.frame(width: 60, height: 60)
.shadow(radius: 10)
Image(systemName: viewController.myLocationButtonPressed ? "location.fill" : "location")
.foregroundColor(.blue)
}
}
}
}
}
This is my viewController
import UIKit
import SwiftUI
import GoogleMaps
class ViewController: UIViewController, ObservableObject {
#Published var myLocationButtonPressed: Bool = false
#IBOutlet var mapView: GMSMapView!
override func viewDidLoad() {
super.viewDidLoad()
// My Location Button
let myLocationView = MyLocationView(viewController: self)
let hostingController = UIHostingController(rootView: myLocationView)
hostingController.view.backgroundColor = .blue
addChild(hostingController)
hostingController.view.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(hostingController.view)
hostingController.didMove(toParent: self)
NSLayoutConstraint.activate([
hostingController.view.leadingAnchor.constraint(equalTo: view.leadingAnchor),
hostingController.view.topAnchor.constraint(equalTo: view.topAnchor),
hostingController.view.trailingAnchor.constraint(equalTo: view.trailingAnchor),
hostingController.view.bottomAnchor.constraint(equalTo: view.bottomAnchor)
])
}
}
Any idea why the button action is not working here?
