Mapbox Directions for Swift
Mapbox Directions for Swift makes it easy to connect your iOS, macOS, tvOS, or watchOS application to the Mapbox Directions and Map Matching APIs. Quickly get driving, cycling, or walking directions, whether the trip is nonstop or it has multiple stopping points, all using a simple interface reminiscent of MapKit’s MKDirections API. Fit a GPX trace to the OpenStreetMap road network. The Mapbox Directions and Map Matching APIs are powered by the OSRM and Valhalla routing engines. For more information, see the Mapbox Navigation homepage.
Mapbox Directions pairs well with MapboxGeocoder.swift, MapboxStatic.swift, the Mapbox Navigation SDK for iOS, and the Mapbox Maps SDK for iOS or macOS SDK.
Installation
Specify the following dependency in your Carthage Cartfile:
github "mapbox/mapbox-directions-swift" ~> 2.14
Or in your CocoaPods Podfile:
pod 'MapboxDirections', '~> 2.14'
Or in your Swift Package Manager Package.swift:
.package(url: "https://github.com/mapbox/mapbox-directions-swift.git", from: "0.30.0")
Then import MapboxDirections.
Configuration
You’ll need a Mapbox access token in order to use the API. If you’re already using the Mapbox Maps SDK for iOS or macOS SDK, Mapbox Directions automatically recognizes your access token, as long as you’ve placed it in the MBXAccessToken key of your application’s Info.plist file.
Starting points
Directions is the main class that represents the Mapbox Directions and Map Matching APIs. To calculate directions between coordinates, configure a RouteOptions object and pass it into Directions.calculate(_:completionHandler:). Similarly, to match a trace to the road network, configure a MatchOptions object and pass it into either Directions.calculate(_:completionHandler:) or Directions.calculateRoutes(matching:completionHandler:). These methods asynchronously send requests to the API, then form Route or Match objects that correspond to the API’s response.
A Route object is composed of one or more RouteLegs between waypoints, which in turn are composed of one or more RouteSteps between maneuvers. Depending on the request, a RouteStep may additionally contain objects representing intersection- and segment-level data. A Match object is structured similarly, except that it provides additional details about how the trace matches the road network.
For further details, consult the guides and examples included with this API reference. To integrate real-time turn-by-turn navigation into your iOS application, see “Navigation SDK”.
