The Rasat page provides a detailed overview, installation instructions, as well as various methods and usage guidelines of the Rasat iOS Swift library developed and maintained by Ahmet Keskin. The Rasat library is a basic module designed to provide reactive programming options for Swift programmers working on iOS applications.
Introduction
Rasat is a lightweight Observable pattern library for Swift language, which provides mechanisms for creating and working with observables in Swift programming. It can be used with iOS, macOS and watchOS applications.
Installation
The Rasat library can be integrated into a Swift project using Swift Package Manager, which is the recommended method. The GitHub link to the library must be added to the dependencies in the Swift project’s package. There is no requirement to import any kind of modules as the library is a Swift package.
dependencies: [
.package(url: "https://github.com/ahmetkgunay/Rasat.git", from: "1.0.1")
]
Creating an Observable
An Observable is created by instantiating the Observable class provided by the Rasat library. This can be done by passing the generic type to the class constructor.
let observable = Observable<String>()
Subscribing to an Observable
Subscriptions to an Observable take place through the ‘subscribe’ method provided by the Observable class instance. A closure can be passed as the subscriber, which will receive all future updates from the observable.
let subscription = observable.subscribe { value in
print(value)
}
Sending events
Once the Observable instance has a subscriber, it can send events using the ‘send’ method. The send method will pass the event to all subscribers of the observable.
observable.send("Hello, Rasat!")
Unsubscribing
Unsubscribing from an Observable instance is as simple as subscribing. The ‘dispose’ method on the received subscription instance is called, it will effectively stop the subscriber from receiving further updates.
subscription.dispose()
Conclusion
Rasat offers Swift developers a new way to implement reactive programming patterns within their apps. As a lightweight, simple library, it can be easily integrated into any project to provide effective, clean, and concise Observable pattern implementations.
