This silences a compatibility warning that was introduced in a previous refactor that changed the return type of the callout view for annotation delegate method. This also adds checks to ensure that the callout view provided by the delegate to the map view is of the correct type and conforms to the correct protocol.
Mapbox iOS SDK
A library based on Mapbox GL Native for embedding interactive map views with scalable, customizable vector maps into Cocoa Touch applications on iOS 8.0 and above using Objective-C, Swift, or Interface Builder.
This repository is for day-to-day development of the SDK. Building the SDK yourself requires a number of dependencies and steps that are unnecessary for developing production applications. For production applications, please consider installing an official, prebuilt release instead; see the Mapbox iOS SDK website for installation instructions.
