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.

- 4. RX SWIFT COCOA ▸ Cocoa, which includes the Foundation and AppKit frameworks, is used for developing applications that run on macOS (OS X)
- 5. RX SWIFT COCOA TOUCH ▸ Cocoa Touch, which includes the Foundation and UIKit frameworks, is used for developing applications that run on iOS

- 8. RX SWIFT WHAT ARE OBSERVABLES ▸ 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 ARE SUBJECTS ▸ 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 ▸ Traits in 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.

- 20. RX SWIFT DISPOSING WITH RX COCOA ▸ nothing : Inside singletons or a view controller which are never released. ▸ unowned : Inside all view controllers which are released after the closure task is performed. ▸ weak : any other case.
