let kCLLocationAccuracyBestForNavigation: CLLocationAccuracy

The highest possible accuracy that uses additional sensor data to facilitate navigation apps.

let kCLLocationAccuracyBest: CLLocationAccuracy

The best level of accuracy available.

let kCLLocationAccuracyNearestTenMeters: CLLocationAccuracy

Accurate to within ten meters of the desired target.

let kCLLocationAccuracyHundredMeters: CLLocationAccuracy

Accurate to within one hundred meters.

let kCLLocationAccuracyThreeKilometers: CLLocationAccuracy

Accurate to the nearest three kilometers.
