Installation

The Swift Package Manager is a tool for managing the distribution of Swift code and is integrated into the swift compiler.

1. Add the package to the dependencies in your Package.swift file.

   let package: Package = .init(
       ...
       dependencies: [
           .package(url: "https://github.com/alexandrehsaad/swift-locations.git", branch: "main")
       ],
       ...
   )

2. Add the package as a dependency on your target in your Package.swift file.

   let package: Package = .init(
       ...
       targets: [
           .target(name: "MyTarget", dependencies: [
               .product(name: "Locations", package: "swift-locations")
           ]),
       ],
       ...
   )

3. Import the package in your source code.

   import Locations

Demonstration

1. Initiate the locater with your desired accuracy.

   let locater: Locater = .init(accuracy: .tenMetres)

2. Request the user’s permission to use location services and do something with the asynchronous value you receive. You can not show to the user an authorization dialog twice, but you can show the steps to change the permission from Settings.

   do {
       let status: AuthorizationStatus = try await locater.requestAlwaysAuthorization()
   	// Do something with the status.
       print(status)
   } catch let error {
       // Do something with the error.
       print(error)
   }

3. Subscribe to the locater and do something with the asynchronous stream of values you receive. The return type is Point, which conforms to a new protocol PlottableInTwoDimensions.

   do {
       let stream: AsyncStream<CLLocation> = try locater.subscribe()
       for await data in stream {
           // Do something with the data.
           print(data)
       }
   } catch let error {
       // Do something with the error.
       print(error)
   }

4. Unsubscribe from the locater.

   locater.unsubscribe()

Troubleshooting common errors

Your app must include usage description keys in its Info.plist file for the types of data it needs. Failure to include these keys cause the app to crash. To access location data specifically, it must include either NSLocationWhenInUseUsageDescription or NSLocationAlwaysAndWhenInUseUsageDescription.
