Polyline

@MainActor
@preconcurrency
struct Polyline
 
extension Polyline : MapContent, MapContentTappable, Sendable, SendableMetatype, View

A 3D polyline that can be placed on a map.

Map(mode: .hybrid) {
  Polyline(path: [
    .init(latitude: 37.7749, longitude: -122.4194, altitude: 100),
    .init(latitude: 37.7750, longitude: -122.4193, altitude: 100),
    .init(latitude: 37.7751, longitude: -122.4192, altitude: 100),
  ])
}

  • 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

  • Declaration

    Swift

    struct ContourStyle
     
    extension Polyline.ContourStyle : Equatable, Hashable

  • Declaration

    Swift

    struct StrokeStyle
     
    extension Polyline.StrokeStyle : Equatable, Hashable

  • Specifies how altitudes in the path are interpreted. Default value: clampToGround.

    Declaration

    Swift

    @MainActor
@preconcurrency
var 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 }

  • Declaration

    Swift

    @MainActor
@preconcurrency
func contour(_ style: Polyline.ContourStyle) -> Polyline

  • Values that define how polylines are drawn to represent the contour of the Earth.

    Declaration

    Swift

    @MainActor
@preconcurrency
var contourStyle: Polyline.ContourStyle

  • Declaration

    Swift

    @MainActor
@preconcurrency
init(path: [LatLngAltitude], altitudeMode: AltitudeMode = .clampToGround, zIndex: Int32 = 0)

  • Sets the path of the polyline in LatLngAltitude coordinates.

    Declaration

    Swift

    @MainActor
@preconcurrency
var path: [LatLngAltitude]

  • Declaration

    Swift

    @MainActor
@preconcurrency
func stroke(_ style: Polyline.StrokeStyle) -> Polyline

  • Stroke style of the polyline.

    Declaration

    Swift

    @MainActor
@preconcurrency
var strokeStyle: Polyline.StrokeStyle

  • The draw order compared to other polys. Default value: 0.

    Declaration

    Swift

    @MainActor
@preconcurrency
var zIndex: Int32
