Protocols

protocol CustomNSError
Describes an error type that specifically provides a domain, code, and user-info dictionary.
protocol NSCacheDelegate
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 NSDecimalNumberBehaviors
protocol NSKeyedArchiverDelegate
The NSKeyedArchiverDelegate protocol defines the optional methods implemented by delegates of NSKeyedArchiver objects.
protocol NSKeyedUnarchiverDelegate
protocol NSLocking
protocol NSMutableCopying
The 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
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 PortDelegate
protocol ProgressReporting
If your class supports reporting progress, then you can adopt the ProgressReporting protocol.
protocol RecoverableError
Describes an error that may be recoverable by presenting several potential recovery options to the user.
protocol ReferenceConvertible
Decorates types which are backed by a Foundation reference type.
protocol StreamDelegate

Types

struct AffineTransform
AffineTransform represents an affine transformation matrix of the following form:
struct AlignmentOptions
class BlockOperation
class Bundle
class ByteCountFormatter
struct CGFloat
struct CGPoint
struct CGRect
enum CGRectEdge
struct CGSize
struct CharacterSet
A CharacterSet represents a set of Unicode-compliant characters. Foundation types use CharacterSet to group characters together for searching operations, so that they can find any of a particular set of characters during a search.
class DateFormatter
class DateIntervalFormatter
class Dimension
class EnergyFormatter
class FileHandle
class Formatter
class Host
class ISO8601DateFormatter
struct IndexSet
Manages a Set of integer values, which are commonly used as an index type in Cocoa API.
enum InflectionRule
class InputStream
class JSONSerialization
class LengthFormatter
class MassFormatter
struct Measurement<UnitType>
A Measurement is a model type that holds a Double value associated with a Unit.
struct Morphology
class NSAffineTransform
struct NSAffineTransformStruct
A structure that defines the three-by-three matrix that performs an affine transform between two coordinate systems.
class NSArray
class NSAttributedString
struct NSBinarySearchingOptions
class NSCache<KeyType, ObjectType>
class NSCalendar
class NSCharacterSet
class NSCoder
The NSCoder abstract class declares the interface used by concrete subclasses to transfer objects and other values between memory and some other format. This capability provides the basis for archiving (where objects and data items are stored on disk) and distribution (where objects and data items are copied between different processes or threads). The concrete subclasses provided by Foundation for these purposes are NSKeyedArchiver and NSKeyedUnarchiver. Concrete subclasses of NSCoder are referred to in general as coder classes, and instances of these classes as coder objects (or simply coders). A coder object that can only encode values is referred to as an encoder object, and one that can only decode values as a decoder object.
class NSCompoundPredicate
class NSCondition

class NSEnumerator
class NSError
struct NSExceptionName

class NSIndexPath
class NSIndexSet
struct NSIndexSetIterator
class NSKeyedArchiver
NSKeyedArchiver, a concrete subclass of NSCoder, provides a way to encode objects (and scalar values) into an architecture-independent format that can be stored in a file. When you archive a set of objects, the class information and instance variables for each object are written to the archive. NSKeyedArchiver’s companion class, NSKeyedUnarchiver, decodes the data in an archive and creates a set of objects equivalent to the original set.
class NSKeyedUnarchiver

struct URLError
Describes errors in the URL error domain.
struct URLFileResourceType
struct URLResourceKey
struct URLResourceValues
URLs to file system resources support the properties defined below. Note that not all property values will exist for all file system URLs. For example, if a file is located on a volume that does not support creation dates, it is valid to request the creation date property, but the returned value will be nil, and no error will be generated.
class Unit
class UnitAcceleration
