@frozen struct ObjectIdentifier
In Swift, only class instances and metatypes have unique identities. There is no notion of identity for structs, enums, functions, or tuples.
init(AnyObject) Creates an instance that uniquely identifies the given class instance.
init(Any.Type) Creates an instance that uniquely identifies the given metatype.
var debugDescription : StringA textual representation of the identifier, suitable for debugging.
var hashValue : IntThe hash value.
func hash(into: inout Hasher)Hashes the essential components of this value by feeding them into the given hasher.
static func != (ObjectIdentifier, ObjectIdentifier) -> Bool Returns a Boolean value indicating whether two values are not equal.
static func ... (ObjectIdentifier) -> PartialRangeFrom<ObjectIdentifier> Returns a partial range extending upward from a lower bound.
static func ... (ObjectIdentifier) -> PartialRangeThrough<ObjectIdentifier> Returns a partial range up to, and including, its upper bound.
static func ... (ObjectIdentifier, ObjectIdentifier) -> ClosedRange<ObjectIdentifier> Returns a closed range that contains both of its bounds.
static func ..< (ObjectIdentifier) -> PartialRangeUpTo<ObjectIdentifier> Returns a partial range up to, but not including, its upper bound.
static func ..< (ObjectIdentifier, ObjectIdentifier) -> Range<ObjectIdentifier> Returns a half-open range that contains its lower bound but not its upper bound.
static func < (ObjectIdentifier, ObjectIdentifier) -> Bool Returns a Boolean value indicating whether the value of the first argument is less than that of the second argument.
static func <= (ObjectIdentifier, ObjectIdentifier) -> Bool Returns a Boolean value indicating whether the value of the first argument is less than or equal to that of the second argument.
static func == (ObjectIdentifier, ObjectIdentifier) -> Bool Returns a Boolean value indicating whether two values are equal.
static func > (ObjectIdentifier, ObjectIdentifier) -> Bool Returns a Boolean value indicating whether the value of the first argument is greater than that of the second argument.
static func >= (ObjectIdentifier, ObjectIdentifier) -> Bool Returns a Boolean value indicating whether the value of the first argument is greater than or equal to that of the second argument.
struct MirrorA representation of the substructure and display style of an instance of any type.
func type<T, Metatype>(of: T) -> MetatypeReturns the dynamic type of a value.
func == (Any.Type?, Any.Type?) -> Bool Returns a Boolean value indicating whether two types are identical.
func != (Any.Type?, Any.Type?) -> Bool Returns a Boolean value indicating whether two types are not identical.
