same issue here, it was working fine with iOS 12, now all annotations near the current location marker are not visible anymore. Critical information might be near the user location and needs to be displayed. This is mostly bad when you zoom out the map, as you don't know anymore if there is data since all annotations comes near the user location...

Is there a document that indicates this change from apple? I didn't find any... thanks in advance for someone that finds it.

If there is no options to turn off this behavior, the only workaround I can think of is to manually add the current location annotation ourselves...

blocks|key|3081107|text|在MKMapViewDelegate上的回调-mapView:viewForAnnotation中，请确保您返回的MKAnnotationView将其displayPriority保留为默认值，即MKFeatureDisplayPriorityRequired，否则MapKit会将注释视图与用户位置进行集群。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3081108|entityMap^0|23|F|2Q|W|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

In the callback -mapView:viewForAnnotation on your MKMapViewDelegate be sure that the MKAnnotationView you return leaves its <code>displayPriority</code> as its default value which is <code>MKFeatureDisplayPriorityRequired</code> otherwise MapKit clusters your annotation view with the user location.

Using MKPinAnnotationView instead of MKAnnotationView has fixed my issue

<pre><code>- (MKAnnotationView *)mapView:(MKMapView *)tempMapView viewForAnnotation:(id &lt;MKAnnotation&gt;)tempAnnotation{
 if ([tempAnnotation isKindOfClass:[MKUserLocation class]]){
 return nil;
 }
 NSString *identifer = @"Identifer";
 MKPinAnnotationView *dPV = [[MKPinAnnotationView alloc] initWithAnnotation:tempAnnotation reuseIdentifier:identifer];
 [dPV setSelected:YES];
 [dPV setTag:102];
 dPV.canShowCallout = YES;
 [dPV setSelected:YES];
 dPV.draggable = YES;
 return dPV;}
</code></pre>

blocks|key|764989|text|对于那些有问题的人，我有一个解决办法。我在我的生产应用程序中也遇到了问题，因为我只是将注释添加到地图中，而从不调用viewForAnnoation方法。我创建了一个示例项目并将其上传到Github，这样您就可以查看代码并了解我做了什么。简而言之，您需要创建一个子类NSObject并符合MKAnnotation协议的类。如果像我的项目一样使用MKLocalsearch，请传回MKMapItem对象并创建新类的新实例。您还需要创建一个类和子类MKMarkerAnnotationView。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|764990|++++class+CustomMKMarkerSubclass:+MKMarkerAnnotationView+{

I have a fix for those having issues. I was having issues in my production app as well because I was just adding the annotations to the map and never calling the viewForAnnoation method. I created a sample project and uploaded it to Github so you can review the code and see what I did. In short, you need to create a class that subclasses NSObject and conforms to the MKAnnotation protocol. If using MKLocalsearch like my project, pass the MKMapItem object back and create a new instance of the new class. You will also need to create a class and subclass MKMarkerAnnotationView. 

<pre><code> class CustomMKMarkerSubclass: MKMarkerAnnotationView {
 override var annotation: MKAnnotation? {
 willSet {
 if let _ = newValue as? MapLocation {
 displayPriority = MKFeatureDisplayPriority.required
 canShowCallout = true
 }
 }
 }
}
</code></pre>

It seems like iOS 14 fixed this issue

Currently, when I try to add an annotation to the map in the user's location the annotation is not showing up. When I set the annotation (using the same code) besides the user's location it does show up.

The code:

<pre><code>let annotation = MKPointAnnotation()
annotation.coordinate = coordinate // set coordinate
annotation.title = "Title"
annotation.subtitle = "Subtitle"
mapView.addAnnotation(annotation)
</code></pre>
