It allows you to use Publishers from common types you’re already familiar with. The Foundation framework contains a lot of extensions to work with Combine. Keep this in mind while we go over some Publishers’ examples in the Foundation framework while working with Combine. A Publisher exposes values that can change on which a subscriber subscribes to receive all those updates. If you’re familiar with RxSwift:ĭifferent namings, but they both give the same understanding. The Combine framework comes with so-called Publishers and subscribers.

This will help you to understand better how the code works and behaves. Before we dive straight into the code examples, it’s better to start with some background information. The basic principles of Combine make you understand how it works and how you can use it.

I want to map it’s data to a JSON model.

In other words, a FRP sequence could be described as follows: Examples of these kinds of values include network responses, user interface events, and other types of asynchronous data. Functional Reactive Programming (FRP) languages allow you to process values over time. It allows you to write functional reactive code by providing a declarative Swift API. You can compare the Combine framework to frameworks like RxSwift and ReactiveSwift (formally known as ReactiveCocoa). Hopefully, after reading this blog post, you should be able to answer the above questions, and you’re able to understand what Combine can do. What does it actually mean? What can I do with it, and when should I use it?Īpple describes the framework as follows:Ĭustomize handling of asynchronous events by combining event-processing operators.
