Marker

@MainActor
@preconcurrency
struct Marker<Content> where Content : View
 
extension Marker : MapContent, MapContentAnchorable, Sendable, SendableMetatype, View

A type that allows you to display custom SwiftUI content over the Map, anchored to a position on the 3D map.

Default content is a Pin view.

Map(mode: .hybrid) {
  Marker(position: .init(latitude: 37.7749, longitude: -122.4194, altitude: 0)) {
    Image(systemName: "car")
  }
}

  • The type of view representing the body of this view.

    When you create a custom view, Swift infers this type from your implementation of the required View/body-swift.property property.

    Declaration

    Swift

    typealias Body = some View

  • The altitude interpretation for the position.

    Declaration

    Swift

    @MainActor
@preconcurrency
let altitudeMode: AltitudeMode

  • The content and behavior of the view.

    When you implement a custom view, you must implement a computed body property to provide the content for your view. Return a view that’s composed of built-in views that SwiftUI provides, plus other composite views that you’ve already defined:

    struct MyView: View {
    var body: some View {
        Text("Hello, World!")
    }
}

    For more information about composing views and a view hierarchy, see doc:Declaring-a-Custom-View.

    Declaration

    Swift

    @MainActor
@preconcurrency
var body: some View { get }

  • Creates a Marker anchored to a specific coordinate.

    Declaration

    Swift

    @MainActor
@preconcurrency
init(position: LatLngAltitude, altitudeMode: AltitudeMode = .clampToGround, collisionBehavior: CollisionBehavior = .required, collisionPriority: Int? = nil, @ViewBuilder content: () -> Content = { Pin() })

    Parameters

    position

    The geographic coordinate to anchor to.
    altitudeMode

    The altitude interpretation for the position. Default value: .clampToGround.
    collisionBehavior

    The collision behavior of the Marker. Default value: .required.
    collisionPriority

    A number which is used to help determine relative priority between optional collision behavior markers. A higher collisionPriority value indicates higher priority.
    content

    The SwiftUI view to display inside the Marker. Default value: Pin().

  • The geographic coordinate to anchor the Marker to.

    Declaration

    Swift

    @MainActor
@preconcurrency
let position: LatLngAltitude
