Conformances

• 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 Error

  A type representing an error value that can be thrown.

• protocol Hashable

  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

  The NSObjectProtocol groups methods that are fundamental to all Foundation objects.

• protocol NSSecureCoding

  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.

• protocol Sendable

  A type whose values can safely be passed across concurrency domains by copying.
