RxSwift is the Swift-specific implementation of the Reactive Extensions standard.. Reactive programming helps you write applications that are more powerful and efficient. But why is reactive programming so cool? Are you aware of a technology to make the app even better, or just more delightful? The point is, we would like to see the temperature — amongst other information — of the current brew all the time within the app. You can read the whole snippet of the MVVM example.

RxSwift belongs to a large family of Rx implementations in different programming languages that share almost identical syntax and semantics. : Up to date for Swift 4.2, Xcode 10.1 & RxSwift 4.4. It’s all about moving logic to the view model and reducing the responsibility of the view controller. For example, all changes to the model will be automatically reflected in the associated view. Swift has seen many changes since its release in 2014. Let’s start from zero. When it comes to handling network communication methods — which is not exactly black magic nowadays — you’ll end up just like Thomas the Tank Engine, working a big fat controller, responsible for getting the data from all sources and rendering them to the UI at the same time. Copyright © 2020 Apple Inc. All rights reserved. That’s why we decided to write an introduction to reactive programming in Swift.

The definition could be further shortened simply like this: Reactive programming is programming with asynchronous data streams Cechy produktu. You can write more software, help more people, and create applications that scale. Let’s get back to MVVM, and the temperature we were looking for. You can write more software, help more people, and create applications that scale. Now that we understand that the key for representing mutable models in MVVM’s view is data binding, what can be better at carrying out our bindings than some reactive magic? Wow, that’s.. a lot? Key-Value Observing (KVO) is our friend. With the view’s complexity growing, it’s just not worth the effort. Start with an introduction to the reactive programming paradigm; learn about observers and observables, filtering and transforming operators, and how to work with the UI, and finish off by building a fully-featured app in RxSwift.

But now check how it looks in the MVVM style: These are the variables to store inside the view model, they look a bit strange, but I couldn’t see how to make it less weird (and I also wanted to shed a negative light on this solution, maybe I’m kind of biased already). iOS tech lead. I started with the plain old MVC version of the app, first in Objective-C. Reactive programming is a growing paradigm that we will help you set to work in Swift. The concept of switching your programming concepts from imperative to functional reactive programming will also be covered. There comes a huge amount of boilerplate code with KVO implementation, but it’s still more lightweight than an application written in the MVC style, especially when we think of putting more and more complexity into our application — into our view model. Let’s go back in time to when Apple introduced Swift, the successor to good old Objective-C, it was a very different time. If you have experience with MVC on iOS/Mac, I bet you’ve already seen view controllers responsible for a lot more than you wanted in the first place.
