We just open-sourced MapboxNavigation.swift, our navigation SDK for iOS applications written in Swift or Objective-C. When your users want directions, don’t push them out of your application into a generic map application; instead, keep them engaged with your application 100% of the time with in-app turn-by-turn navigation. MapboxNavigation.swift is powered by MapboxDirections.swift and our Directions API with realtime traffic. You control the entire experience, from the time your user chooses a destination to when they arrive.
