What is Nssecurecoding?
A protocol that enables encoding and decoding in a manner that is robust against object substitution attacks.
What is an NSCoder?
NSCoder 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 (storing objects and data on disk) and distribution (copying objects and data items between different processes or threads).
What is NSCoding in Swift?
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).
What is serialization in IOS?
2019. Serialization is a process of converting your instances to another representation, like a string or a stream of bytes. The reverse process of turning the data into an instance is called decoding, or deserialization.
What is swift Codable?
Codable is the combined protocol of Swift’s Decodable and Encodable protocols. Together they provide standard methods of decoding data for custom types and encoding data to be saved or transferred.
What are decoders used for?
Introduction to Decoder The decoder is an electronic device that is used to convert a digital signal to an analog signal. It allows a single input line and produces multiple output lines. The decoders are used in many communication projects that are used to communicate between two devices.
What is NSObject in Swift?
The root class of most Objective-C class hierarchies, from which subclasses inherit a basic interface to the runtime system and the ability to behave as Objective-C objects.
What does NS in NSObject mean?
The Foundation Kit, or just Foundation for short, is an Objective-C framework in the OpenStep specification. It provides basic classes such as wrapper classes and data structure classes. This framework uses the prefix NS (for NeXTSTEP). It is also part of Cocoa and of the Swift standard library.
What is serialization with example?
Serialization is a mechanism of converting the state of an object into a byte stream. Deserialization is the reverse process where the byte stream is used to recreate the actual Java object in memory. This mechanism is used to persist the object.
What is the use of NSObject?
NSObject class: (source). AnyObject protocol: its a implicit confirmation of any object. You use AnyObject when you need the flexibility of an untyped object or when you use bridged Objective-C methods and properties that return an untyped result.
