One debate over the past year in the iOS ecosystem was the around functional reactive framework like RxSwift or ReactiveCocoa. This year at WWDC2019, Apple took position on it and released their own functional reactive programming framework, here is Combine.

I have been recently asked to review an iOS application to see how healthy was the code base, if it follows the best practices and how easy it would be to add new features to it. If I review some code on daily basis for small pull requests, analysing one whole app at once is quite different exercice. Here is some guidelines to help doing that analysis.

After weeks experimenting different patterns and code structures, I wanted to go further in functional reactive programming and see how to take advantage of it while following Coordinator pattern. This post describes how integrate RxSwift with Coordinator pattern and which mistakes to avoid.

If you are not familiar with it, Redux a Javascript open source library designed to manage web application states. It helps a lot to make sure your app always behaves as expected and makes your code easier to test. ReSwift is the same concept but in Swift. Let’s see how.

We often talk about scalability of iOS app but not much about the project itself or the team. How to prepare your project to move from 2 developers to 6? How about 10 or 20 more? In that research, I’ve listed different tools to prepare your team and project to scale.

For the past months, I keep going further in RxSwift usage. I really like the idea of forwarding events through different layers but the user interface stays sometimes a challenge. Today, I’ll describe how to use RxDataSources to keep things as easy as possible.

Even if I usually stay focus on the customer facing side of mobile development, I like the idea of writing backend api with all the security that Swift includes. Starting small, why not using Swift Server for our UI Tests to mock content and be at the closest of the real app.

I love developing new iOS apps and create new products. However, regardless of the project, it often need a team to mix the required skills: design, coding, marketing. Although, this less and less true, so let’s see how to bootstrap your iOS app.

Not that long ago, I wrote how to pair RxSwift with MVVM architecture in an iOS project. Even if I refactored my code to be reactive, I omitted to mention the unit tests. Today I’ll show step by step how to use RxTest to unit test your code.

For years now, the whole iOS community has written content about the best way to improve or replace the Apple MVC we all started with, myself included. MVC, MVVM, MVP, VIPER? Regardless the type of snake you have chosen, it’s time to reflect on that journey.
