Observable-Swift is a Swift library providing explicit value observing via Observable<T> and subscribable events via Event<T>, inspired by Objective-C's KVO. It supports chained observables, before/after change handlers, multiple handlers, and observer lifetime management using closures and generics.
Use cases
- observe value changes on Swift variables with closures
- implement KVO-like observing in Swift without Objective-C keys
- subscribe to custom events with Event<T>
- chain observables for key-path-style observation
- add multiple change handlers and tie them to observer lifetime
When to avoid
- you need Combine, RxSwift, or full reactive streams with operators
- your project requires actively maintained libraries with recent Swift version support
- you rely on implicit KVO of arbitrary object properties
