Make sure you are not using dispatch_async for the map.

I had the following function that did not work in iOS11

dispatch_async(dispatch_get_main_queue(), ^{
    @synchronized(_queue) {
        if(poppedMapView != nil) {
            [self.queue removeObject:poppedMapView];
        }
        [self.queue addObject:[[MKMapView alloc] init]];
    }
});

Changed it to

if(poppedMapView != nil) {
    [self.queue removeObject:poppedMapView];
}
[self.queue addObject:[[MKMapView alloc] init]];
