LocationManager

Location Manager

This application demonstrates how to build a simple application for both iOS and macOS using CoreLocation and MapKit. It displays a map and allows you to search for points of interest on the map by category (e.g. cafe, museum, etc). You can also center the map on your current location, if you allow access.

The core logic of the application is written a single time, and powers both views. All of the code shared between the iOS and macOS apps is in the Common Swift package. It has:

• Core business logic implemented as a reducer that operates on the domain state, actions and environment.
• A thin wrapper around the MKLocalSearch API that allows us to search for points of interest on the map.
• A wrapper around MKMapView to make it usable from SwiftUI.

Interaction with CoreLocation's CLLocationManager API is done via the ComposableCoreLocation library that comes with the Composable Architecture. It gives you an Effect-friendly interface to all of CLLocationManager's APIs, making it easy to use its features from a reducer and making it easy to test logic that depends on its CLLocationManager's functionality.
