Crash when trying to download areas beyond -85.0511 (max area allowed in OSM)

[merlos]

In Open Street Maps (OSM), the max latitude that can be converted to tiles is +85.0511 and the minimum is -85.0511 (see https://wiki.openstreetmap.org/wiki/Slippy_map_tilenames).

However in Apple Maps allows to download from -90 to 90. So, a map that uses Apple Maps to display the coords will be able to request areas beyond the OSM limit.
