Avoid passing invalid locations along to the map view delegate or user location annotation.
Also, If the user wants to visit the Prime Meridian or Equator, that’s their prerogative. Mapbox GL should show them where they’re at. Null Island is a different story.
Fixes#1912.
Added lightweight generics annotations to collection-typed method and protocol signatures to streamline usage of these members in Swift. Lightweight generic type specifiers are wrapped in conditionally-compiled macros for compatibility with Xcode 6.x.
Manually preprocess the NS_*_OF() macros in a temporary copy of each header before appledoc sees the headers. Also removed the --ignore flag because we no longer have a private headers folder under include/mbgl/ios/.
Added some nullability qualifiers in method implementation selectors for consistency with declarations.
The user dot view now has a non-zero size. Previously only its layer was sized properly. Also resolved some pedantic warnings about missing designated initializer overrides.
Xcode 6.3 or above is now required for building this project.
* Cleans up & documents more APIs, especially in location.
* Moves `coordinate` internal and makes use of `location` to retrieve it.
* Moves `title` & `subtitle` internal since part of `MGLAnnotation` protocol.
* Enables `isUpdating` by privately associating weakly with a map view.
