Polyline

struct Polyline
 
extension Polyline : Copyable, Equatable, Escapable, Hashable, Identifiable, MapContent

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

Map(mode: .hybrid) {
  Polyline(coordinates: [
    .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),
  ])
}

  • Returns a Boolean value indicating whether two values are equal.

    Equality is the inverse of inequality. For any values a and b, a == b implies that a != b is false.

    Declaration

    Swift

    static func == (a: Polyline, b: Polyline) -> Bool

  • Declaration

    Swift

    struct ContourStyle
     
    extension Polyline.ContourStyle : Equatable, Hashable

  • ID

    A type representing the stable identity of the entity associated with an instance.

    Declaration

    Swift

    @available(watchOS, introduced: 6.0)
@available(macOS, introduced: 10.15)
@available(iOS, introduced: 13.0)
@available(tvOS, introduced: 13.0)
typealias ID = String

  • Declaration

    Swift

    struct StrokeStyle
     
    extension Polyline.StrokeStyle : Equatable, Hashable

  • Declaration

    Swift

    func add(coordinator: RenderingCoordinator)

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

    Declaration

    Swift

    var altitudeMode: AltitudeMode

  • Declaration

    Swift

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

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

    Declaration

    Swift

    var contourStyle: Polyline.ContourStyle

  • Sets the coordinates of the polyline.

    Declaration

    Swift

    var coordinates: [LatLngAltitude]

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

    Declaration

    Swift

    var drawOrder: Int32

  • Hashes the essential components of this value by feeding them into the given hasher.

    Implement this method to conform to the Hashable protocol. The components used for hashing must be the same as the components compared in your type’s == operator implementation. Call hasher.combine(_:) with each of these components.

    Important

    In your implementation of hash(into:), don’t call finalize() on the hasher instance provided, or replace it with a different instance. Doing so may become a compile-time error in the future.

    Declaration

    Swift

    func hash(into hasher: inout Hasher)

  • The hash value.

    Hash values are not guaranteed to be equal across different executions of your program. Do not save hash values to use during a future execution.

    Important

    hashValue is deprecated as a Hashable requirement. To conform to Hashable, implement the hash(into:) requirement instead. The compiler provides an implementation for hashValue for you.

    Declaration

    Swift

    var hashValue: Int { get }

  • id

    Unique identifier

    Declaration

    Swift

    let id: String

  • Declaration

    Swift

    init(coordinates: [LatLngAltitude], altitudeMode: AltitudeMode = .clampToGround, drawOrder: Int32 = 0)

  • Declaration

    Swift

    func remove(coordinator: RenderingCoordinator)

  • Declaration

    Swift

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

  • Stroke style of the polyline.

    Declaration

    Swift

    var strokeStyle: Polyline.StrokeStyle

  • Declaration

    Swift

    func update(coordinator: RenderingCoordinator)
