MKTileOverlayRequester with Fatal Exception: NSRangeException

Hello Apple Devs,

I have more then 34 crashes on iOS 11 on iPad and iPhone devices. It's not reproduceble on the prev versions.

This crash related to the MapKit library when presenting my custom tiles.

I have a code with MKTileOverlay class and overrided func "loadTile(at path: MKTileOverlayPath, result: @escaping (Data?, Error?) -> Void)" which returning a tile in an async request from the server. I don't process any arrays and don't know how this crash can happen. It looks like the same issue that the MapKit has with rendering in iOS 11.

Please help with any advice.

We are having the same problems with our code and other issues related to that, such as tiles that render several tiles for no reasons, illegal access crashes in similar MapKit code after a call to result() and it makes our app unstable, which is unfortunate because we're about to release it officially after 2 years of work and this delays our product launch. We never had those kind of problems before ios11, other than the occasional out of memory errors that were caused by leaks. It really is annoying and two days of scouting the code for errors brought no solution.

Hi here!


Same with various devices on iOS 11 but also iOS 12. The GEOTileServerLocalProxy.workQueue thread randomly crash.


I've also a very simple custom object of MKTileOverlay with customization of loadTileAtPath.


Basically like you guys.
