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),
  ])
}

• Body

  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

• ContourStyle

  Declaration

  Swift

  struct ContourStyle

  extension Polyline.ContourStyle : Equatable, Hashable

• StrokeStyle

  Declaration

  Swift

  struct StrokeStyle

  extension Polyline.StrokeStyle : Equatable, Hashable

• altitudeMode

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

  Declaration

  Swift

  @MainActor
  @preconcurrency
  var altitudeMode: AltitudeMode

• body

  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 }

• contour(_:)

  Declaration

  Swift

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

• contourStyle

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

  Declaration

  Swift

  @MainActor
  @preconcurrency
  var contourStyle: Polyline.ContourStyle

• init(path:altitudeMode:zIndex:)

  Declaration

  Swift

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

• path

  Sets the path of the polyline in LatLngAltitude coordinates.

  Declaration

  Swift

  @MainActor
  @preconcurrency
  var path: [LatLngAltitude]

• stroke(_:)

  Declaration

  Swift

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

• strokeStyle

  Stroke style of the polyline.

  Declaration

  Swift

  @MainActor
  @preconcurrency
  var strokeStyle: Polyline.StrokeStyle

• zIndex

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

  Declaration

  Swift

  @MainActor
  @preconcurrency
  var zIndex: Int32
