GreatCircle is an Swift framework that provides a set of extensions to the CLLocation
class.
The CLLocation
class provides only one method for calculating the distance between two GPS locations:
func distance(from location: CLLocation) -> CLLocationDistance
This means that Swift developers must "roll their own" to solve more complex GPS location calculation problems.
GreatCircle provides a comprehensive set of extension methods to the CLLocation
class that
make working with GPS locations and performing calculations on then simple and easy.
GreatCircle is a example of standing on the shoulders of giants:
- It's a Swift port of the Objective C GreatCircle library by Brian Lambert
- Which is, in turn, based upon the work of Chris Veness, the owner of the Geodesy functions project
