MapKit how to opt-out from clustering when an annotation is selected

Question

I’m using iOS 11 clustering and it works really fine, basically you just need to ad an identifier to the clusteringIdentifier property of an MKAnnotationView.
Everything works perfectly but I have an issue, when a user select a marker from a map I'd like to avoid clustering at least on the selected maker.
The mapView doesn't seems to have a property to disable clustering. The only plausible solution is to nil clusteringIdentifier, but even if I do that it keeps to cluster.

func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {  
         view.clusteringIdentifier = nil  
    }

Can someone post me in the right direction?

There is no such thing as `view.clusterIdentificator`. – matt Apr 18 '19 at 23:07 — matt, Apr 18 '19 at 23:07
I correct the question it was a typo – Andrea Apr 19 '19 at 12:36 — Andrea, Apr 19 '19 at 12:36

Give the clusteringIdentifier a unique value. If the clusteringIdentifier has a value that is not shared with any other annotation views, it won't cluster with any other annotation views.

You can obtain a unique value by saying UUID().uuidString.

UUID().uuidString for swift 4.2 and beyond – JBarros35 Apr 30 '20 at 15:46
@JBarros35 Thanks, I'll just change it directly – matt Apr 30 '20 at 16:09
@matjan thanks, it's odd how much difficulty I seem to have getting this right. :) – matt Sep 14 '20 at 16:41
I have this question too. How do I set the clusteringIdentifier of the members on the did select to get them to vacate the cluster? Thanks! – devjme Nov 13 '20 at 18:54
