Implementing SwiftUI Live Location Updates: A Comprehensive Guide

Tracking location updates in real time has become essential in many mobile applications. Whether you're developing a navigation app or a location-based service, continuous updates on the user's whereabouts can enhance the user experience significantly. In this guide, we will explore how to implement live location updates using SwiftUI and Core Location.

The Problem: Detecting Location Changes

Imagine you have created an ObservableObject in SwiftUI that is designed to track the user's location. Everything appears to be functioning correctly, and you can receive location updates. However, you notice that the message "location changed" is only printed once. This is indicative of a common pitfall: the location updates are not being retrieved continuously.

The root cause of the issue is the line of code that stops location updates after the first retrieval:

This line of code effectively tells the CLLocationManager to cease gathering further location data, which is why you only see the "location changed" message a single time.

The Solution: Continuously Requesting Location Updates

To solve this problem, we need to modify our existing code to ensure that location updates are requested continuously. Rather than stopping the updates after the first location is retrieved, we should allow the location manager to keep running and updating our location as necessary.

Step-by-Step Solution

Remove the Stop Update Call:
First, we need to comment out or delete the line that stops the location updates:

Adjust the Location Manager Logic:
Here is the modified code for our LocationManagerService class:

Test Your Implementation:
After making these changes, run your SwiftUI application on a physical device (as location services may not work accurately on the simulator). You should now see the "location changed" message printed continuously as your location updates.

Conclusion

By following the steps outlined in this guide, you can ensure that your SwiftUI application can effectively track and respond to live location updates. The key takeaway is to let the CLLocationManager handle continuous updates by not stopping it after the first retrieval.

With this guide, you are now equipped to enhance your application with robust location tracking capabilities. Happy coding!
