Hello everyone,
I'm working on a SwiftUI app that requires location services, and I've implemented a LocationManager class to handle location updates and permissions. However, I'm facing an issue where the location permission popup does not appear when the app is launched.
Here is my current implementation:
LocationManager.swift:
import CoreLocation
import SwiftUI
class LocationManager: NSObject, ObservableObject, CLLocationManagerDelegate {
private let locationManager = CLLocationManager()
@Published var userLocation: CLLocation?
@Published var isAuthorized = false
@Published var authorizationStatus: CLAuthorizationStatus = .notDetermined
override init() {
super.init()
locationManager.delegate = self
checkAuthorizationStatus()
}
func startLocationUpdates() {
locationManager.startUpdatingLocation()
}
func stopLocationUpdates() {
locationManager.stopUpdatingLocation()
}
func requestLocationAuthorization() {
print("Requesting location authorization")
DispatchQueue.main.async {
self.locationManager.requestWhenInUseAuthorization()
}
}
private func checkAuthorizationStatus() {
print("Checking authorization status")
authorizationStatus = locationManager.authorizationStatus
print("Initial authorization status: \(authorizationStatus.rawValue)")
handleAuthorizationStatus(authorizationStatus)
}
func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) {
print("Authorization status changed")
authorizationStatus = manager.authorizationStatus
print("New authorization status: \(authorizationStatus.rawValue)")
handleAuthorizationStatus(authorizationStatus)
}
private func handleAuthorizationStatus(_ status: CLAuthorizationStatus) {
switch status {
case .authorizedAlways, .authorizedWhenInUse:
DispatchQueue.main.async {
self.isAuthorized = true
self.startLocationUpdates()
}
case .notDetermined:
requestLocationAuthorization()
case .denied, .restricted:
DispatchQueue.main.async {
self.isAuthorized = false
self.stopLocationUpdates()
print("Location access denied or restricted")
}
@unknown default:
DispatchQueue.main.async {
self.isAuthorized = false
self.stopLocationUpdates()
}
}
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
DispatchQueue.main.async {
self.userLocation = locations.last
}
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print("Location manager error: \(error.localizedDescription)")
}
}
MapzinApp.swift:
@main
struct MapzinApp: App {
@UIApplicationDelegateAdaptor(AppDelegate.self) var delegate
@StateObject private var locationManager = LocationManager()
var body: some Scene {
WindowGroup {
Group {
if locationManager.authorizationStatus == .notDetermined {
Text("Determining location authorization status...")
} else if locationManager.isAuthorized {
CoordinatorView()
.environmentObject(locationManager)
} else {
Text("Location access is required to use this app. Please enable it in Settings.")
}
}
}
}
}
Log input:
Checking authorization status
Initial authorization status: 0
Requesting location authorization
Authorization status changed
New authorization status: 0
Requesting location authorization
Despite calling requestWhenInUseAuthorization() when the authorization status is .notDetermined, the permission popup never appears. Here are the specific steps I have taken:
Checked the Info.plist to ensure the necessary keys for location usage are present:
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
NSLocationAlwaysAndWhenInUseUsageDescription
Verified that the app's target settings include location services capabilities.
Tested on a real device to ensure it's not a simulator issue.
I'm not sure what I might be missing. Any advice or suggestions to resolve this issue would be greatly appreciated. Thank you!
