Where to put delegates of CLLocationManager using Swift UI? - swiftui

Question

I've been on and off Swift for the years so, sorry if I'm doing something stupid, the Swift UI thing isn't helping my confusion either. I have the code I'm working with at the bottom.
So I'm making a Geofencing app using SwiftUI, I've got the basics up and running but still have a bit to go with it,
I have the Geofencing coordinates and stuff inside the UserData environment variable, which I get off a json elsewhere.
Have a SwiftUI object that has a map out with the current position and initializes a CLLocationManager to deal with geofencing.
I'm trying to implement the delegate on the same file by
locationManager.delegate = self
in the setupManager(),
but it will cause
Cannot assign value of type 'GeofencingView' to type 'CLLocationManagerDelegate?'
The lack of SwiftUI specific information online seems to be causing the most confusion for me at the moment, I think what I should do is,
create a customized NsObject that handles the delegates, but in that case I'm not sure how to pass the #EnviromentObject
Find out how to put the delegates on the UIViewRepresentable object.
Any pointers on what I'm doing wrong would be greatly appreciated.
import SwiftUI
import MapKit
import CoreLocation
struct GeofencingView: UIViewRepresentable {
#EnvironmentObject var userData: UserData
var notification = LocalNotificationManager()
var locationManager = CLLocationManager()
func setupManager() {
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestWhenInUseAuthorization()
locationManager.requestAlwaysAuthorization()
self.startGoefenceMonitoring()
}
func startGoefenceMonitoring() {
print("MapListView::startGeofenceMonitoring")
for landmark in self.userData.landmarks {
let moniteringCordinate = CLLocationCoordinate2DMake(landmark.locationCoordinate.longitude, landmark.locationCoordinate.latitude)
let moniteringRegion = CLCircularRegion.init(center: moniteringCordinate, radius: 20.0, identifier: "\(landmark.id)" )
locationManager.startMonitoring(for: moniteringRegion)
}
}
func makeUIView(context: Context) -> MKMapView {
setupManager()
let mapView = MKMapView(frame: UIScreen.main.bounds)
let count = self.userData.landmarks.count
var annotationArray: [MKAnnotation] = []
var num:Int = 0
mapView.showsUserLocation = true
mapView.userTrackingMode = .follow
return mapView
}
func updateUIView(_ uiView: MKMapView, context: Context) {
}
}
struct GeofencingView_Preview: PreviewProvider {
static var previews: some View {
GeofencingView()
.environmentObject(UserData())
}
}
