Description
An MBTiles source could be implemented as a plugin to the map SDK.
Although MBTiles is a Mapbox-supported tile container format, the Mapbox Maps SDK doesn’t support it out of the box as a way to sideload offline maps. https://github.com/mapbox/mapbox-gl-native/issues/6862#issuecomment-287484550 explains the situation in more detail.
Fortunately, iOS map SDK v4.0.0 will introduce MGLComputedShapeSource for supplying tiles to the rendering engine on demand. It should therefore be possible to implement MBTiles support in a plugin that adds a computed shape source to the map.
See mapbox/mbxmapkit#3 for tips on how this feature was implemented in the legacy Mapbox iOS SDK (source code no longer publicly accessible).

Review mapbox/mapbox-gl-native#9983 for related context. Done means an iOS plugin can use an MBTiles source to provide sideloaded offline maps through the map SDK.
