NSDictionary
class NSDictionaryclass NSDictionaryimport Foundationclass NSObjectThe root class of most Foundation class hierarchies.
protocol CopyableA type whose values can be implicitly or explicitly copied.
protocol CustomDebugStringConvertibleA type with a customized textual representation suitable for debugging purposes.
protocol CustomReflectableA type that explicitly supplies its own mirror.
protocol CustomStringConvertibleA type with a customized textual representation.
protocol EquatableA type that can be compared for value equality.
protocol Escapableprotocol ExpressibleByDictionaryLiteralA type that can be initialized using a dictionary literal.
protocol Hashable : EquatableA type that can be hashed into a Hasher to produce an integer hash value.
protocol NSCodingThe 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 NSCopyingThe 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 NSMutableCopyingThe NSMutableCopying protocol declares a method for providing mutable copies of an object. Only classes that define an “immutable vs. mutable” distinction should adopt this protocol. Classes that don’t define such a distinction should adopt NSCopying instead.
protocol NSObjectProtocol : AnyObjectThe NSObjectProtocol groups methods that are fundamental to all Foundation objects.
protocol NSSecureCoding : NSCodingConforming 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 Sequence<Element>A type that provides sequential, iterated access to its elements.
