rxcocoa

RxCocoa is a powerful library that brings Reactive Programming to Cocoa applications. It provides an elegant way to compose asynchronous events and data streams, using reactive principles.

Features:

  • Reactive extensions for Cocoa.
  • Enables composing asynchronous events and data streams.
  • Provides powerful operators for transforming, filtering, and combining events.
  • Seamless interoperation with RxSwift and RxRelay libraries.
  • Supports various interfaces and functionalities in Cocoa, like UIKit and AppKit.

Installation:

RxCocoa can be installed using CocoaPods, Carthage, or Swift Package Manager. Choose the option that suits your project best:

CocoaPods:

To integrate RxCocoa into your project using CocoaPods, add the following line to your Podfile:

pod 'RxCocoa'

Then run the command:

pod install

Carthage:

To use RxCocoa with Carthage, add the following line to your Cartfile:

github "ReactiveX/RxCocoa"

Then run the following two commands:

carthage update
carthage build --no-use-binaries

Swift Package Manager:

You can also add RxCocoa as a dependency in your Package.swift file:

.package(url: "https://github.com/ReactiveX/RxCocoa.git", from: "6.1.0")

Then include it as a dependency in your target:

.target(
    name: "YourTarget",
    dependencies: ["RxCocoa"]),

Usage:

RxCocoa provides various extensions and operators for different Cocoa interfaces. Here are some examples of how to use RxCocoa in your project:

UIKit:

If you’re working with UIKit, you can use RxCocoa to handle user interfaces.

Observing Control Events:

To observe control events, you can use controlEvent(_:) operator:

button.rx.controlEvent(.touchUpInside)
    .subscribe(onNext: { _ in
        // Handle button tap
    })
    .disposed(by: disposeBag)

Observing Text Changes:

If you want to observe text changes in a UITextField or UITextView:

textField.rx.text
    .orEmpty
    .subscribe(onNext: { text in
        // Handle text change
    })
    .disposed(by: disposeBag)

AppKit:

RxCocoa also provides support for AppKit interfaces.

Observing Control Events:

To observe control events in AppKit interfaces:

myButton.rx.controlEvent(.leftMouseDown)
    .subscribe(onNext: { _ in
        // Handle left mouse button click
    })
    .disposed(by: disposeBag)

Observing Text Changes:

If you want to observe text changes in an NSTextField or NSTextView:

myTextField.rx.text
    .orEmpty
    .subscribe(onNext: { text in
        // Handle text change
    })
    .disposed(by: disposeBag)

These are just a few examples. RxCocoa provides many more operators and extensions for Cocoa interfaces. Please refer to the official documentation for more details.
