You probably found yourself in a situation where you had to do a bunch of asynchronous tasks and you just wanted to get notified when all of them finish. There are two easy ways of doing this: DispatchGroup and OperationQueue. We’ll cover them both in this post. The Story We’ll… Read more »
There are more ways than one to do concurrent operations on iOS. In this article, we’ll cover how to use Operations and OperationQueue to execute concurrent operations. There’s a lot to be said (and written) about concurrency on iOS and I don’t really want to bore you to death by… Read more »
If you started your iOS development career in Objective-C, especially pre ARC Objective-C, you’re probably very familiar with the above-mentioned concepts. If you started with Swift, some of them might be a bit murky, hopefully, by the end of this post, you’ll get to know them a bit better. A… Read more »
Generics is one powerful feature of swift that allows us to work with generic types. In this article, we’ll cover what generics are, and how to use them in your project. Generics You must have come across the term ‘generics’ when working in swift. They’re those funky things in angle… Read more »
Everyone has heard of singletons. It’s probably the simplest design pattern there is, yet, there are a few catches when implementing it. In this post, I’ll go over the singleton design pattern and the little gotchas that might end up in a crash or an inconsistent state of the app. Singleton… Read more »
There are more than a few search algorithms. Today we’ll examine one of them, the Binary Search Algorithm, and we’ll implement this algorithm using an array extension in swift. We’ll also compare the performance of this algorithm to your standard brute force search, and see how it compares. Binary Search Algorithm… Read more »
Sorting algorithms are an important feature of modern computing, and in this article we’ll examine some of the most common sorting algorithms in use today. Implementations of these algorithms will be done in swift, but they are language agnostic, and you should have on problems implementing them in a language… Read more »
In computer science there are many data structures. In this post we will examine one such structure called a ‘Stack’. We’ll implement it using another data structure called a ‘Linked List’, and for the sake of comparison, we will implement the same stack data structure using plain old arrays, and… Read more »
Snakes and Ladders is a popular game that we all played as children. For those of you who are new to the game, it’s a simple game played on a board that consists of 10×10 squares. The player moves by throwing a dice, you start from square 1, and move… Read more »
