I'm not 100% sure that's the Mapbox related bug but please have a look. Xcode 7.1 (7B91b), Mapbox ios-v3.0.0-pre.4.

My IBAction which have caused the bug:

@IBAction func centerOnUser(sender: AnyObject) {

// Remove all annotations
      mapView.removeAnnotations(mapView.annotations!)

// Add annotations from Realm db.
      populateMap()

// Center map to current user location.
      centerToUsersLocation()
    }

There’s not much to go on here. Do you see anything in the console?

Per https://github.com/mapbox/mapbox-gl-native/issues/2962#issuecomment-155163224, I wonder if pulling in 7b8b2b1790863c7103067d40c690e273a8af5198 would fix the issue.

I usually get this error only with real devices (iPhone 5S or 6Plus) during my daily commute to work and back.

I guess, the scenario to bring about that error is:

Use an app with good network connection (3G/4G/Wi-Fi) and without any problems to detect user location.
Then move to the underground (subway/tube), an app must be running in background mode (usually core location can't determine proper user location under the ground) and after you finish your subway travel and you will be on a street, try to update map and center to the user location and you should get this crash.

I hope you understand the idea.

Anyway, if you can give me any advice on how I can debug this error, I’ll be grateful.

ps: I didn't have this kind of error when I used Mapkit in my app but I've rewritten my app completely and I have not finished unit tests yet, so maybe that is my bug...

Sort of looks like the Swift version of a crash we've been seeing. It's also tough to debug and I'm not entirely certain it's from Mapbox code.

Thanks for the report @minikin -- that last stack trace is a bug that was fixed shortly after 3.0.0pre5 (in 7b8b2b1790863c7103067d40c690e273a8af5198). We're going to release pre6 soon. Sorry for the inconvenience!

friedbunny commented 8 years ago

Going to close this as it's not particularly actionable. @minikin if you learn anything new, please reopen.
