Structures

struct AffineTransform
AffineTransform represents an affine transformation matrix of the following form:
struct AlignmentOptions
struct AttributeContainer
struct AttributeScopeCodableConfiguration
struct AttributedString
struct AttributedSubstring
struct CGFloat
struct CGPoint
struct CGRect
struct CGSize
struct Calendar
Calendar encapsulates information about systems of reckoning time in which the beginning, length, and divisions of a year are defined. It provides information about the calendar and support for calendrical computations such as determining the range of a given calendrical unit and adding units to a given absolute time.
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.
struct CocoaError
Describes errors within the Cocoa error domain.
struct CodableConfiguration
struct Data
struct Date
Date represents a single point in time.
struct DateComponents
DateComponents encapsulates the components of a date in an extendable, structured manner.
struct DateInterval
DateInterval represents a closed date interval in the form of [startDate, endDate]. It is possible for the start and end dates to be the same with a duration of 0. DateInterval does not support reverse intervals i.e. intervals where the duration is less than 0 and the end date occurs earlier in time than the start date.
struct Decimal
struct FileAttributeKey
struct FileAttributeType
struct IndexPath
IndexPath represents the path to a specific node in a tree of nested array collections.
struct IndexSet
Manages a Set of integer values, which are commonly used as an index type in Cocoa API.
struct Locale
Locale encapsulates information about linguistic, cultural, and technological conventions and standards. Examples of information encapsulated by a locale include the symbol used for the decimal separator in numbers and the way dates are formatted.
struct Measurement
A Measurement is a model type that holds a Double value associated with a Unit.
struct Morphology
struct NSAffineTransformStruct
A structure that defines the three-by-three matrix that performs an affine transform between two coordinate systems.
struct NSBinarySearchingOptions
struct NSEdgeInsets
struct NSEnumerationOptions
struct NSExceptionName
************* Exceptions **********
struct NSIndexSetIterator
struct NSSortOptions
struct NSTextCheckingKey
struct NSZone
struct Notification
Notification encapsulates information broadcast to observers via a NotificationCenter.

struct PersonNameComponents
struct ProgressKind
struct ProgressUserInfoKey
struct ScopedAttributeContainer
struct StreamNetworkServiceTypeValue
struct StreamSOCKSProxyConfiguration
struct StreamSOCKSProxyVersion
struct StreamSocketSecurityLevel
struct StringTransform
struct TimeZone
TimeZone defines the behavior of a time zone. Time zone values represent geopolitical regions. Consequently, these values have names for these regions. Time zone values also represent a temporal offset, either plus or minus, from Greenwich Mean Time (GMT) and an abbreviation (such as PST for Pacific Standard Time).
struct URL
A URL is a type that can potentially contain the location of a resource on a remote server, the path of a local file on disk, or even an arbitrary piece of encoded data.
struct URLComponents
A structure designed to parse URLs based on RFC 3986 and to construct URLs from their constituent parts.
struct URLError
Describes errors in the URL error domain.
struct URLFileResourceType
struct URLQueryItem
A single name-value pair, for use with URLComponents.
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.
struct UUID
Represents UUID strings, which can be used to uniquely identify types, interfaces, and other items.

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 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.

Protocols

protocol AttributeScope
protocol AttributedStringAttributeMutation
protocol AttributedStringKey
protocol AttributedStringProtocol
protocol ContiguousBytes
Indicates that the conforming type is a contiguous collection of raw bytes whose underlying storage is directly accessible by withUnsafeBytes.
protocol CustomNSError
Describes an error type that specifically provides a domain, code, and user-info dictionary.
protocol DataProtocol
protocol DecodableAttributedStringKey
protocol DecodableWithConfiguration
protocol DecodingConfigurationProviding
protocol EncodableAttributedStringKey
protocol EncodableWithConfiguration
protocol EncodingConfigurationProviding
protocol FileManagerDelegate
protocol LocalizedError
Describes an error that provides localized messages describing why an error occurred and provides more information about the error.
protocol MarkdownDecodableAttributedStringKey
protocol MutableDataProtocol
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 ObjectiveCConvertibleAttributedStringKey
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
