Swift iOS useless activity reports

Question

I am developing an iOS application using Swift. The application is centered around Apple Maps. I am new to iOS development. I use Fabric.io to beta distribute the application and get crash reports. However, many of the crash reports I receive are not very useful. Sometimes in crash reports, only the way in which the crash occurred is indicated, but it does not give me clues as to why it crashed. I'm trying to figure out if this is standard, or should I switch to another crash reporting service.

Here is an example of such crash reports:

Crashed: com.apple.main-thread
EXC_BREAKPOINT UNKNOWN at 0x00000001000a68f8

Thread : Crashed: com.apple.main-thread

1  <APP NAME>                     0x00000001000a6570 <APP NAME>.MapViewController.(getMapAnnotations (<APP NAME>.MapViewController) -> (Swift.Double, long : Swift.Double) -> ()).(closure #1).(closure #1) (MapViewController.swift)

Here is a method for determining the method in which the error occurs:

func getAnnotations(lat: Double, long: Double){ // ignore the lat long arguments

    var apiWrapper = apiWrapper()

    apiWrapper.search(completionHandler: {(error: NSError?, mediaElements: [MediaElement]?) in
        if error == nil {
            dispatch_async(dispatch_get_main_queue(), {
                self.myMapView!.removeAnnotations(self.myMapView!.annotations)
                self.mediaAnnotations = []
                for m in mediaElements! {
                    var annotation = CustomAnnotation(lat: m.lat,long: m.long, mediaTuple: (media.url, media.type))
                    self.mediaAnnotations.append(annotation)
                }
                self.reorganizeAnnotations(self.mediaAnnotations)
            })
        } 

    })
}
