Basic landmark information and the landmark’s relationship with the target location.
Landmarks are prominent places that can be used to describe a location.
-
Returns a Boolean value indicating whether two values are equal.
Equality is the inverse of inequality. For any values
aandb,a == bimplies thata != bisfalse.Declaration
Swift
static func == ( lhs : Landmark , rhs : Landmark ) -> BoolParameters
lhsA value to compare.
rhsAnother value to compare.
-
The spatial relationship of the target location to the landmark.
Declaration
Swift
enum SpatialRelationshipextension Landmark . SpatialRelationship : Copyable , Equatable , Escapable , Hashable , Sendable , SendableMetatype -
A textual representation of this instance.
Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the
String(describing:)initializer. This initializer works with any type, and uses the customdescriptionproperty for types that conform toCustomStringConvertible:struct Point : CustomStringConvertible { let x : Int , y : Int var description : String { return "( \( x ) , \( y ) )" } } let p = Point ( x : 21 , y : 30 ) let s = String ( describing : p ) print ( s ) // Prints "(21, 30)"The conversion of
pto a string in the assignment tosuses thePointtype’sdescriptionproperty.Declaration
Swift
var description : String { get } -
The landmark’s display name.
Declaration
Swift
var displayName : String ? { get } -
The landmark’s display name language code.
Declaration
Swift
var displayNameLanguageCode : String ? { get } -
Hashes the essential components of this value by feeding them into the given hasher.
Implement this method to conform to the
Hashableprotocol. The components used for hashing must be the same as the components compared in your type’s==operator implementation. Callhasher.combine(_:)with each of these components.Important
In your implementation of
hash(into:), don’t callfinalize()on thehasherinstance 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
hashValueis deprecated as aHashablerequirement. To conform toHashable, implement thehash(into:)requirement instead. The compiler provides an implementation forhashValuefor you.Declaration
Swift
var hashValue : Int { get } -
The landmark’s place ID.
Declaration
Swift
var placeID : String ? { get } -
The landmark’s resource name.
Declaration
Swift
var resourceName : String ? { get } -
Defines the spatial relationship between the target location and the landmark.
Declaration
Swift
var spatialRelationship : Landmark . SpatialRelationship ? { get } -
The straight line distance, in meters, between the center point of the target and the center point of the landmark. In some situations, this value can be longer than
travelDistanceMeters.Declaration
Swift
var straightLineDistanceMeters : Double ? { get } -
The travel distance, in meters, along the road network from the target to the landmark, if known. This value does not take into account the mode of transportation, such as walking, driving, or biking.
Declaration
Swift
var travelDistanceMeters : Double ? { get }
