LocationService

LocationService is a simple, drop-in location manager for iOS written in Swift 4.

It does two things:

1. Handles authorization
2. Fetches the name of a user's current location

It is written so whichever object holds reference to the service (a ViewController, ViewModel, etc) does not have to import CoreLocation or its delegate methods.

It can be expanded upon and improved -- please feel free to submit a pull request if you have changes that make it better!

Notes

Authorization

For authorization, it only accepts When In Use as being properly authorized.
You can customize this yourself in the CLLocationManagerDelegate method.

Location Name

The service defaults to fetching the subLocality and locality as its first priority. It then goes futher up the location hierarchy, until country. If it can't fetch any of the above, it errors out.
These priorities can be changed in LocationService's reverseGeocode(...) method.

Example Usage

final class ViewController: UIViewController {

	let locationService = LocationService()

	var locationName: String? 

// ... 

	func requestLocationName() {

		locationService.requestLocationName({ locationName, error in
			if let name = locationName {
				self.locationName = name
			} else if let error = error {
				// Handle error here
			}
		})
	}

}
