geojson

Motivation

I often use this pattern for GeoJSON sources:

1. addSource('mysource', { type: 'geojson', data: { type:'FeatureCollection', features: [] }});
2. addLayer({ id: 'mylayer', source: 'mysource' })
3. Now fetch the actual data, manipulate it, and call setData() to set it.

I do this because:

• I need to fetch the data asynchronously (but I don't want to hold up all my other i

MGLTilePyramidOfflineRegion should have a countOfTiles method that returns the number of tiles included in the tile pyramid. The implementation would rely on the mbgl::util::tileCount() function added in #9906.

This is the iOS/macOS equivalent to #11108 for Android. It would serve as a built-in alternative to mapbox/turf-swift#47 for applications already using the map SDK, including applica

Hello Maurits,
This is more of a request than it is an actual issue, but I think the value in this request is really high (for newcomers, especially - but not limited to).
Could you please add a COMPLETE application example of using the API (with user authentication, maybe even with the user-creation SQL script, table authorization, etc).
This would be really really helpful as a quickstart /

For me, it's a problem regarding I control if these polygons are not intersecting.

map_coords() has an obvious use case in transforming the geometry of features.

It should operate on Features and FeatureCollections, as well.
