[Rx] rx cocoa
This document discusses RxSwift and Cocoa, which are frameworks for reactive programming in iOS and macOS apps. It explains that Cocoa and Cocoa Touch include frameworks for developing macOS and iOS apps respectively. It then covers key RxSwift concepts like Observables, Subjects, Control Properties, Control Events, and Drivers. It also discusses how to bind data with RxSwift, use traits like ControlProperty and ControlEvent, and how to properly dispose of subscriptions to avoid memory leaks.

- 8. RX SWIFT WHAT AREOBSERVABLES ▸ The heart of Rx ▸ Rx : observable, observable sequence, sequence (same) ▸ Observables emits events (emit) ▸ Events can contain values or can be recognized gestures

- 10. RX SWIFT WHAT ARESUBJECTS ▸ Subject is a sort of bridge or proxy that is available in some implementations of ReactiveX that act both an observable and an observer ▸ PublishSubject - starts empty and only emits new elements to subscribers ▸ BehaviorSubject - starts with an initial value and replays it or the latest element to new subscriber ▸ ReplaySubject - initialized with a buffer size and will maintain a buffer of elements up to that size and replay it to new subscribers ▸ Variable - wraps a BehaviorSubject, preserve its current value as state, and replays only the latest/initial value to new subscribers
- 11. RX SWIFT TRAITS ▸ Traitsin general is an optional part of the framework, you are not forced to use it. ▸ If you want some checks while compiling and nice restrictions when dealing with the UI, these components are extremely powerful and time saving.
- 12. RX SWIFT TRAITS ▸ ControlProperty: It is used to bind the data to the correct user interface components using the rx extension. ▸ ControlEvent : It is used to listen to a certain event of the UI components. ▸ Driver : A special observable can’t error out. All processes are ensured to execute on the main thread, which avoids making UI changes on background threads.
