Written by Aaaaand, I’m back. It’s been a long time since I posted anything here. Mainly this was because I worked full time for a while. I found it hard to work all day on someone else’s project, then come home and do even more blog-worthy code-related stuff. At the end of the work day I was […]
Introduced in 2019, Apple made UI implementation much simpler with With SwiftUI its UI declarative framework. After some time experiencing with it, I’m wondering today if MVVM is still the best pattern to use with. Let’s see what has changed, implementing MVVM with SwiftUI. Prerequisite Before starting, if you are not too familiar with MVVM […]
Hello and welcome to another blog post about SwiftUI. This time, we will talk about the animation of complex shapes in SwiftUI. You will understand animatableData property and will be able to implement animatable custom Shape struct that depends on multiple parameters. AnimatableData Animating simple shapes is easy thanks to animatableData property. We have seen […]
In this article, I try to summarize the bare minimum one needs to know to add internationalization support to an iOS app. Localizations, locales, timezones, date and currency formatting… it’s shocking how easy is to forget how they work and how to use them correctly. After years more than 10 years into iOS development, I […]
As iOS developers, a lot of our work involves taking models from a server, and transforming them to be displayed on an iPhone or iPad. This sounds like a job for some declarative architecture. 🤔 If you ask 3 programmers how to define MVVM, expect to get 7 different responses. — ✨ Joe Fabisevich™ ✨ […]
If you haven’t checked out Part I, I recommend reading it because if you don’t, none of writing below will make sense! Three Unanswered Questions 1. What happens when the views you want to configure are more complex? My recommended approach is to construct a one-time use struct, specifically for displaying in that one place. […]
When asked about data structure and algorithm for an iOS development role, there is always this idea that it’s not a knowledge needed. Swift got already native data structure, right? Isn’t the rest only UI components? That’s definitely not true. Let’s step back and discuss about data structure and algorithm applied to iOS development. If […]
The journey we took to restructure our mobile apps towards a modular architecture. Originally published on the Just Eat Engineering Blog. Overview Modular mobile architectures have been a hot topic over the past 2 years, counting a plethora of articles and conference talks. Almost every big company promoted and discussed modularization publicly as a way […]
A11yUITests is an extension to XCTestCase that adds tests for common accessibility issues that can be run as part of an XCUITest suite. I’ve written a detailed discussion of the tests available if you’re interested in changing/implementing these tests yourself. Alternatively, follow this quick start guide. Getting Started Adding A11yUITests I’m assuming you’re already familiar […]
For a while now I’ve been looking at possibilities for automated accessibility testing on iOS. Unfortunately, I’ve not found any option so far that I’m happy with. I am a big fan of Apple’s XCUI Test framework. Although it has its limitations, I believe there’s scope for creating valid accessibility tests using this framework. Over […]
