KVOcompatible
KVOcompatible is a protocol in the Swift programming language designed to facilitate Key-Value Observing (KVO) in a more type-safe and Swift-friendly manner. KVO is a mechanism in Apple's Cocoa framework that allows objects to be notified of changes to specific properties of other objects. Traditionally, KVO in Objective-C required the use of strings to specify the property keys, which could lead to runtime errors if the keys were misspelled or changed.
The KVOcompatible protocol addresses these issues by providing a type-safe way to observe property changes. By
To use KVOcompatible, a class must adopt the protocol and implement the required initializer. The class can
KVOcompatible is particularly useful in SwiftUI, where it can be used to observe changes to state properties
