The MapLibre Maps SDK for iOS is an open-source framework for embedding interactive map views with scalable, customizable vector maps into Cocoa Touch applications on iOS 9.0 and above using Objective-C, Swift, or Interface Builder. It takes stylesheets that conform to the MapLibre GL Style Specification, applies them to vector tiles that conform to the Mapbox Vector Tile Specification, and renders them using OpenGL. It is based on the MapLibre GL Native library.
