# MapAnnotation A customizable annotation that marks a map location. ``` struct MapAnnotation where Content : View ``` ## Overview Use [`MapAnnotation`](/documentation/MapKit/MapAnnotation) to declare the layout of the view that MapKit uses for the annotation. Create a [`Map`](/documentation/MapKit/Map) and display annotations by returning a view that conforms to [`MapAnnotationProtocol`](/documentation/MapKit/MapAnnotationProtocol) from the trailing closure of [`init(coordinateRegion:interactionModes:showsUserLocation:userTrackingMode:annotationItems:annotationContent:)`](/documentation/MapKit/Map/init(coordinateRegion:interactionModes:showsUserLocation:userTrackingMode:annotationItems:annotationContent:)) or [`init(mapRect:interactionModes:showsUserLocation:userTrackingMode:annotationItems:annotationContent:)`](/documentation/MapKit/Map/init(mapRect:interactionModes:showsUserLocation:userTrackingMode:annotationItems:annotationContent:)). Items you provide as a collection to the source annotations need to conform to . For example, the following code displays a map and a single annotation: ```swift struct IdentifiablePlace: Identifiable { let id: UUID let location: CLLocationCoordinate2D init(id: UUID = UUID(), lat: Double, long: Double) { self.id = id self.location = CLLocationCoordinate2D( latitude: lat, longitude: long) } } struct CustomAnnotationMapView: View { let place: IdentifiablePlace @State var region: MKCoordinateRegion var body: some View { Map(coordinateRegion: $region, annotationItems: [place] ) { place in MapAnnotation(coordinate: place.location) { Rectangle().stroke(Color.blue) .frame(width: 20, height: 20) } } } } ``` ## Topics ### Creating a map annotation [`init(coordinate:anchorPoint:content:)`](/documentation/MapKit/MapAnnotation/init(coordinate:anchorPoint:content:)) Creates a custom annotation that provides a SwiftUI view to display at the map location that you specify. ## Relationships ### Conforms To [`MapAnnotationProtocol`](/documentation/MapKit/MapAnnotationProtocol) --- Copyright © 2026 Apple Inc.
