# annotations(in:) Returns the annotation objects within the specified map rectangle. ``` func annotations(in mapRect: MKMapRect) -> Set ``` ## Parameters `mapRect` The portion of the map that you want to search for annotations. ## Return Value The set of annotation objects within `mapRect`. ## Discussion This method offers a fast way to retrieve the annotation objects in a particular portion of the map. It’s much faster than doing a linear search of the objects in the [`annotations`](/documentation/MapKit/MKMapView/annotations) property yourself. --- Copyright © 2026 Apple Inc.
