Shortly stepping back from coding for a week and reading about the community, I realized it how easy it is to be crushed by anxiety: I see so many great things happening every day, things I want to be part of, but at the same time getting anxiety to be good enough. This is my […]
In the last couple years, Apple has made some good efforts to improve their testing tools. Today, I’ll walk you through some tips to make sure your test suite run at their best capacity. Project configuration and testing environment If you haven’t added yet some unit tests in your app, the first step is to […]
A recurring challenge in programming is accessing a shared resource concurrently. How to make sure the code doesn’t behave differently when multiple thread or operations tries to access the same property. In short, how to protect from a race condition? To build a Thread-safe data structure, we need to briefly walk through concurrency principles in […]
About a month ago, it became possible to run Swift code on AWS Lambda. I was really interesting to try and see how easy it would be to deploy small Swift functions as serverless application. Let’s see how. If you missed the news, Swift code running on AWS Lambda is available under couple conditions, but […]
Even though the iOS ecosystem is growing further every day from Objective-C, some companies still heavily rely on it. A week away for another wave of innovation from WWDC 2020, I thought it would be interesting to dive back into Objective-C starting with a MVVM pattern implementation. As a quick reminder, MVVM pattern is an […]
Since January, I’ve been slowing down blogging for couple reasons: I started doubting about myself and the quality of my content but I also wanted to focus more on some fundamentals I felt I was missing. So I committed to a “100 day challenge” coding challenge, focused on data structure and algorithm in Swift. Before […]
Following up previous articles about common data structure in Swift, this week it’s time to cover the Tree, a very important concept that we use everyday in iOS development. Let’s dive in. Concept Opposite to linear structure that we’ve covered like Queue or Stack, a Tree is hierarchical structure represented by a set of linked […]
Recently, I was looking into a bug where the UITabBar was inconsistently disappearing on specific pages. I tried different approaches but I couldn’t get where it got displayed and hidden. That’s where I thought about KVO. Some background on my issue, I had a custom TabBarController inheriting UITabBarController which hides or shows its tabBar based […]
After covering last week how to code a Queue in Swift, it sounds natural to move on to the Stack, another really handy data structure which also find his place in iOS development. Let’s see why. Concept Similar to a Queue, a Stack execute operation in a linear order, however the ordered is reversed to […]
Recently revisiting computer science fundamentals, I was interested to see how specific data structure applies to iOS development, starting this week one of most common data structure: the queue. My daily usage of data structure is often limited to native one available in iOS development: arrays, sets, dictionaries. However, if there is a data structure […]
