protocol CustomDebugStringConvertible
A type with a customized textual representation suitable for debugging purposes.
protocol CustomStringConvertible
A type with a customized textual representation.
protocol Equatable
A type that can be compared for value equality.
protocol Hashable : Equatable
A type that can be hashed into a Hasher
to produce an integer hash value.
protocol NSCoding
The NSCoding
protocol declares the two methods that a class must implement so that instances of that class can be encoded and decoded. This capability provides the basis for archiving (where objects and other structures are stored on disk) and distribution (where objects are copied to different address spaces).
protocol NSCopying
The NSCopying
protocol declares a method for providing functional copies of an object. The exact meaning of “copy” can vary from class to class, but a copy must be a functionally independent object with values identical to the original at the time the copy was made.
protocol NSObjectProtocol : AnyObject
The NSObjectProtocol
groups methods that are fundamental to all Foundation objects.
protocol NSSecureCoding : NSCoding
Conforming to the NSSecureCoding
protocol indicates that an object handles encoding and decoding instances of itself in a manner that is robust against object substitution attacks.
