## Observable-Swift


### Overview


Observable-Swift is a framework that provides reactive programming capabilities to Swift applications. It allows developers to easily implement the observer pattern and create reactive chains of events.


### Installation


To add Observable-Swift to your project, you can use the following methods:


#### Cocoapods


To install using Cocoapods, add the following line to your `Podfile`:

“`ruby
pod ‘Observable-Swift’
“`
Then run `pod install`.


#### Carthage


To install using Carthage, add the following line to your `Cartfile`:

“`ruby
github “Observable-Swift/Observable-Swift”
“`
Then run `carthage update` and follow the integration steps provided by Carthage.


### Getting Started


Observable-Swift simplifies reactive programming in Swift by utilizing the concept of observables and observers. Here’s how you can get started with Observable-Swift:


#### Creating an Observable


To create an observable, you can use the `Observable` class provided by Observable-Swift. Here’s an example:


“`swift
let observable = Observable()
“`


#### Subscribing to an Observable


To receive updates from an observable, you need to subscribe to it. Observable-Swift provides the `subscribe` method for this purpose. Here’s an example:


“`swift
observable.subscribe { value in
// Handle the received value here
}
“`


#### Emitting Values


To emit values from an observable, you can use the `emit` method. Here’s an example:


“`swift
observable.emit(“Hello, World!”)
“`


### Advanced Usage


Observable-Swift offers more advanced features to enhance your reactive programming experience. Some of these features include:


#### Filter


The `filter` operator allows you to filter values emitted by an observable based on a condition. Here’s an example:


“`swift
observable.filter { value in
return value.count > 5
}.subscribe { value in
// Handle filtered values here
}
“`


#### Map


The `map` operator allows you to transform values emitted by an observable into a different type. Here’s an example:


“`swift
observable.map { value in
return value.uppercased()
}.subscribe { value in
// Handle transformed values here
}
“`


#### Merge


The `merge` operator allows you to merge multiple observables into one. Here’s an example:


“`swift
let otherObservable = Observable()
let merged = observable.merge(with: otherObservable)

merged.subscribe { value in
// Handle values emitted by merged observable
}
“`
