Put gaps between! — Before we start Difficulty: Beginner | Easy | Normal | Challenging This article has been developed using Xcode 12.2, and Swift 5.3 Prerequisites This article is based on the [UITableView Programmatic Example](), and builds on that (although the code is given in this article I usually remove the storyboard using this technique Keywords and Terminology Row: The…

Surely Nobody Needs To? — The Problem Before iOS 15 AttributedString for SwiftUI wasn’t a thing. Something which might produce the following result:

The classic sorted and unsorted sub arrays — Difficulty: Beginner* | Easy | Normal | Challenging This article covers the classic sorting algorithm Merge Sort, and it’s implementation in Swift. This is seen as a beginner topic (first year Computer Science degree fare) but is certainly not easy. Terminology Algorithm: A process or set of rules to be followed …

5 screens to 1 — If you wish to modify the flow of an App there are many different things that you should be aware of and think about before embarking on the change in your latest sprint. So what should you be thinking about if (say) your login process is to move from 5…

How to avoid these! — The standup A daily standup meeting is performed during Sprints, and functions to keep members of the development team aligned in order to reach the goal of the sprint. …

Algorithms in Swift — Before we start Depth-first search for trees is commonly used for LeetCode challenges, even those rated as Medium or above on the platform. Prerequisites To follow along with this piece, you should be able to create a binary tree using insertions (although a simple implementation is shown below). It would be helpful to be…

Shortcuts and best practices — Unit tests are just as important as your normal programming code. Getting them right is important. Doing a good job is important. Get this right, do. Difficulty: Easy | Normal | Challenging Prerequisites Some basic understanding of functions and methods in Swift. Some String interpolation comes up later, but you can…

Without the Hot Dogs References — I’ve previously written an article where I recreated the code from a Video from WWDC. I’m taking a view about the necessity of viewModels when using SwiftUI, and part of that investigation is around testing. Can I write even simple tests for that code, and get them working? …
