The app crashed when I just stay in it for over 1 hour. I did not do anything else beside staying in it. I have no idea what this log is trying to tell me so if anyone can help me I would appreciate it a lot.
This is the crash log

I'm getting a crash, reported in Crashlytics, and I have no idea how to reproduce the error, It happens randomly so it's hard to debug it with Xcode. Any ideas?

I'm finding it impossible to solve.
I'm getting different kind of crash reports related to VectorKit and MKMapSnapShotter. Crashes occur pretty random, but it seems like they happen most when returning from the background. The device does not send out any memory warnings before it happens.
What's happening here?
I'm using:
if (!_snapshotQueue) {
_snapshotQueue = dispatch_queue_create("com.bestappever.snapshot", DISPATCH_QUEUE_SERIAL);
}
[_snapshotter cancel]
_snapshotter = [[MKMapSnapshotter alloc] initWithOptions:options];
__weak __typeof(self)__self = self;
[_snapshotter startWithQueue:queue completionHandler:^(MKMapSnapshot *snapshot, NSError *error) {
dispatch_async(dispatch_get_main_queue(), ^{
__strong __typeof(__self)_self = __self;
[_self doSomething];
});
}];

How repeatable is this? Is the device coming out of sleep mode? What is on the screen when the App goes into the background?
Within the ViewController you can try registering the NSNotification event, UIApplicationWillResignActiveNotification
When the App is going into the background, calling cancel on any MKMapSnapshotter
If that doesn't work, you could attempt more drastic measures, like hiding views, just to identify if they are related to the crash.
I had the same issue with frequent but random crashes ususally looking like:
VectorKit 0x10663fe9 -[VKTileProvider tileSource:didFetchTile:forKey:] + 105
I fixed it by removing this line:
this.mapSnapshotter.Cancel();
So I think Apple has a bug with the MKMapSnapshotter Cancel method.
Hope that's helpful
