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.

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…
