ObjectIdentifier
A unique identifier for a class instance or metatype.
@frozen struct ObjectIdentifierThis unique identifier is only valid for comparisons during the lifetime of the instance.
In Swift, only class instances and metatypes have unique identities. There is no notion of identity for structs, enums, functions, or tuples.

Type features
static func != (lhs: Self, rhs: Self) -> Bool Returns a Boolean value indicating whether two values are not equal.
static func ... (minimum: Self) -> PartialRangeFrom<Self> Returns a partial range extending upward from a lower bound.
static func ... (maximum: Self) -> PartialRangeThrough<Self> Returns a partial range up to, and including, its upper bound.
static func ... (minimum: Self, maximum: Self) -> ClosedRange<Self> Returns a closed range that contains both of its bounds.
static func ..< (maximum: Self) -> PartialRangeUpTo<Self> Returns a partial range up to, but not including, its upper bound.
static func ..< (minimum: Self, maximum: Self) -> Range<Self> Returns a half-open range that contains its lower bound but not its upper bound.
static func <= (lhs: Self, rhs: Self) -> 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 > (lhs: Self, rhs: Self) -> Bool Returns a Boolean value indicating whether the value of the first argument is greater than that of the second argument.
static func >= (lhs: Self, rhs: Self) -> Bool Returns a Boolean value indicating whether the value of the first argument is greater than or equal to that of the second argument.
