Bump. We're running into this same issue when changing `mapView.tileSource` is it likely to be view lifecycle related @incanus ? We're doing this when the `RMMapView` is loaded, but offscreen.

Just a +1 for the performance issues. Seeing the same in our project.

@joshfisher have fixed this issue at OrdnanceSurvey in our fork, see here: https://github.com/OrdnanceSurvey/mapbox-ios-sdk Have issued PR upstream to Mapbox here: https://github.com/mapbox/mapbox-ios-sdk/pull/611

Agree with this. I wrote a short guide to get my team up to speed quickly. It can be improved in many areas, but might be a good starting point......

Indeed, proj crashes when trying to load the above file. The latest (4.9.2) release of https://github.com/OSGeo/proj.4 does not contain the iOS grid shift file loading fix, but the master branch...

Thanks. Any progress on the upgrade?
