11-16: Add documentation and consider configuration improvements
- Remove redundant nil initialization
- Consider making distance threshold configurable
- Add documentation for public properties
class LiveLocationUpdates { static let shared = LiveLocationUpdates() - private var previousLocation: CLLocation? = nil + private var previousLocation: CLLocation? - private let distanceThreshold: CLLocationDistance = 150.0 + private let distanceThreshold: CLLocationDistance + /// The most recent location update that met the distance threshold criteria @Published var lastLocation = CLLocation() + + private init(distanceThreshold: CLLocationDistance = 150.0) { + self.distanceThreshold = distanceThreshold + }🧰 Tools

11-47: Consider architectural improvements for better flexibility and battery optimization
- Add a delegate protocol for error handling and status updates
- Support different accuracy levels based on use case
- Implement battery optimization strategy (e.g., reduce update frequency when battery is low)
- Consider adding location update batching for more efficient processing
Would you like me to provide a detailed implementation for any of these improvements?

1-6: Remove Duplicate Import of CoreLocationThe
CoreLocationframework is imported twice at the top of the file. Removing the duplicate import cleans up the code.Apply this diff to remove the duplicate import:
import CoreLocation import FirebaseMessaging import Flutter import GoogleMaps -import CoreLocation import Combine
75-89: Reuse Existing Method Channel to Improve PerformanceIn the
sendLocationToFluttermethod, a newFlutterMethodChannelnamed"com.grouptrack/location"is created each time the method is called. Since a method channel with the same name is already initialized inregisterLocationChannel(), consider reusing it to avoid unnecessary creation and improve performance.To implement this, you can store the method channel as a property in
AppDelegateand reuse it:// Add a property to AppDelegate var locationMethodChannel: FlutterMethodChannel? // In registerLocationChannel(), assign the channel to the property private func registerLocationChannel() { let controller: FlutterViewController = window?.rootViewController as! FlutterViewController locationMethodChannel = FlutterMethodChannel( name: "com.grouptrack/location", binaryMessenger: controller.binaryMessenger ) locationMethodChannel?.setMethodCallHandler { [weak self] // existing code } } // Modify sendLocationToFlutter to use the existing channel func sendLocationToFlutter(location: CLLocation) { let locationData: [String: Any] = [ "latitude": location.coordinate.latitude, "longitude": location.coordinate.longitude, "timestamp": location.timestamp.timeIntervalSince1970 * 1000, ] DispatchQueue.main.async { [weak self] in guard let self = self else { return } self.locationMethodChannel?.invokeMethod("onLocationUpdate", arguments: locationData) } }

15-15: LGTM - Project configuration is correct
The new LiveLocationUpdates.swift file is properly integrated into the Xcode project structure with all necessary references and build phase entries.
Also applies to: 60-60, 437-437
15-15: Verify integration with existing location handling
The codebase already contains LocationManager.swift. Please ensure proper coordination between the new and existing location handling mechanisms.
Also applies to: 60-60, 437-437
✅ Verification successful
Let me gather more information about the implementation details of these location handlers to better understand their coordination.
Let me check how these handlers are being used in the AppDelegate to understand their coordination.
Proper coordination between location handlers confirmed
The implementation shows well-coordinated location handling:
- For iOS 17+: Uses
LiveLocationUpdateswith the newCLLocationUpdate.liveUpdatesAPI - For iOS < 17: Uses
LocationsHandlerwith traditionalCLLocationManager - Both handlers publish location updates through Combine framework
- Common
sendLocationToFluttermethod handles location data uniformly - Clear version-based switching in AppDelegate

15-15: Verify iOS version compatibility
The project's deployment target is iOS 14.0, but the new location updates implementation targets iOS 17+. Please ensure:
- Proper fallback mechanism exists for iOS 14-16
- Runtime checks are implemented before using iOS 17+ APIs
Also applies to: 60-60, 437-437
✅ Verification successful
Let me check the implementation details of LiveLocationUpdates.swift to verify the iOS version handling.
Let me check the content of LocationManager.swift to verify the fallback implementation.
Proper fallback mechanism is implemented for iOS 14-16
The code has appropriate version handling and fallback implementation:
- iOS 17+: Uses new
CLLocationUpdateAPI withLiveLocationUpdatesclass - iOS 14-16: Falls back to standard
CLLocationManagerimplementation viaLocationsHandlerclass with:- Background location updates support
- High accuracy settings
- Proper authorization handling
- Location update filtering
The version check and fallback are properly implemented in AppDelegate.swift:
if #available(iOS 17.0, *) {
let liveLocationUpdates = LiveLocationUpdates.shared
// iOS 17+ implementation
} else {
let locationsHandler = LocationsHandler.shared
// iOS 14-16 fallback implementation
}🏁 Scripts executed
The following scripts were executed for the analysis:

The app shouldn't ask for location permission on the onboard screen, It should be from the permission screen only.
