Greetings, in the @main file I keep getting this error, "Thread 1: "-[MTLSimHeap protectionOptions]: unrecognized selector sent to instance 0x600001864d20"" I have no idea what's causing it and how to solve it. Here is the code:
import SwiftUI
import MapKit
struct ContentView: View {
@StateObject private var viewModel = ContentViewModel()
var body: some View {
ZStack {
Map(coordinateRegion: $viewModel.region, showsUserLocation: true)
.accentColor(.blue)
.onAppear{
viewModel.checkIfLocationServicesEnabled()
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
final class ContentViewModel: NSObject, ObservableObject, CLLocationManagerDelegate{
var locationManager: CLLocationManager?
@Published var region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: 37.331516, longitude: -121.891054), span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
func checkIfLocationServicesEnabled() {
if CLLocationManager.locationServicesEnabled() {
locationManager = CLLocationManager()
locationManager!.delegate = self
} else {
print("show alert: location is off.")
}
}
private func checkLocationAuthorization() {
guard let locationManager = locationManager else { return }
switch locationManager.authorizationStatus {
case .notDetermined:
locationManager.requestWhenInUseAuthorization()
case .restricted:
print("Your Location is restricted likely due to parental controls.")
case .denied:
print("You denied this app location permission, go to the settings to change it.")
case .authorizedAlways, .authorizedWhenInUse:
region = MKCoordinateRegion(center: locationManager.location!.coordinate, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
@unknown default:
break
}
}
func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) {
checkLocationAuthorization()
}
}
The @main file:
import SwiftUI
@main
struct MyApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
