LocationApplication

LocationApplication is a Swift Package Manager (SPM) project architected based on the AppState project. This package provides a simplified approach to handling location updates and region monitoring by providing base classes that manage CLLocationManager.

Features

• Streamlines CLLocationManager management, providing a clean and efficient way to handle location updates.
• Leverages AppState for excellent code structure and testability.
• Includes a pre-configured location manager with a singleton design.
• Uses CoreLocation to handle and respond to dynamic location changes in your app.
• Provides a customizable CLLocationManagerDelegate function set.

Getting Started

To add LocationApplication to your Swift project, use the Swift Package Manager. This involves adding a package dependency to your Package.swift file.

dependencies: [
    .package(url: "https://github.com/0xLeif/LocationApplication.git", from: "0.1.0")
]

For App projects, open your project in Xcode and navigate to File > Swift Packages > Add Package Dependency... and enter https://github.com/0xLeif/LocationApplication.git.

Usage

Ensure your files include the following import statements:

import AppState
import CoreLocation
import LocationApplication

Creating a Location Manager

You can access the location manager through the CLLocationManager instance in your application class:

Application.dependency(\.locationManager)

This framework manages most of the dependency injection for you.

Subclassing LocationApplication

Intensive use of location services will likely necessitate subclassing LocationApplication and overriding the necessary CLLocationManagerDelegate functions:

class MyLocationApplication: LocationApplication {
    // Start updating needed infomation from the manager

    // Override CLLocationManagerDelegate functions here
}

Subclassing provides a centralized way to manage all facets of location services in your code.

Using Application.promote

For your subclassed LocationApplication to effectively manage the location updates, it must be promoted to be the active AppState. This can be achieved using the promote function as follows:

Application.promote(to: MyLocationApplication.self)

The promote function supports dynamic injection and replacement of dependencies. It sets your subclass (MyLocationApplication) as the active application state, and all subsequent requests to the Application singleton will result in using the promoted MyLocationApplication.

With this, your custom location manager delegate methods will be used for handling location updates.

Note: Make sure to call Application.promote(to: MyLocationApplication.self) at a suitable time in your application's lifecycle, such as in the didFinishLaunchingWithOptions method in AppDelegate (in UIKit) or the onAppear modifier of the initial view (in SwiftUI).

Remember, when testing, overriding is a useful feature of AppState's Application. Overriding, coupled with dependency injection, provides a powerful tool for isolating units of code for testing. As seen in the LocationApplicationTests, you can override the standard locationManager with a mock location manager for testing, and later cancel the override.
