# MapAnnotation

A customizable annotation that marks a map location.

## Declaration

```swift
struct MapAnnotation<Content> where Content : View
```

## Overview

Overview Use MapAnnotation to declare the layout of the view that MapKit uses for the annotation. Create a Map and display annotations by returning a view that conforms to MapAnnotationProtocol from the trailing closure of init(coordinateRegion:interactionModes:showsUserLocation:userTrackingMode:annotationItems:annotationContent:) or init(mapRect:interactionModes:showsUserLocation:userTrackingMode:annotationItems:annotationContent:). Items you provide as a collection to the source  annotations need to conform to Identifiable. For example, the following code displays a map and a single annotation: 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)             }         }     } }
