In this article I’ll explain how to use map clustering with quad trees using GoogleMaps for iOS. This was done back in December 2015 as back then Google did not have map clustering available for iOS. Since then Google have implemented map clustering using the algorithm described. This was a… Read more »
In this short blog post, we’ll cover some basics on how to use the keychain on iOS, and we’ll create a simple wrapper for the keychain. You’ve probably heard of an iOS keychain. If not, it’s a secure persistent storage, meant to be used to store sensitive information, like passwords,… Read more »
In one of my previous posts, I talked about how to create a temperature sensor using an Arduino and a BLE breakout circuit, and how to read that data from your iOS app. You can read more about it here: Creating a Temperature Sensor for iOS Using BLE and Arduino. In… Read more »
Today we’ll create something cool, a temperature sensor and an iOS app that connects to it. For this project, we’ll be using an Arduino with a BLE breakout circuit. On the iOS side, we’ll be using CoreBluetooth. Don’t worry if some of these things are unfamiliar to you, I’ll try to… Read more »
We all hate entering passwords on our devices, you have to remember the right password, type it in… It’s a drag. Well, since iPhone 5S we’ve got a fingerprint sensor, also called Touch ID. We would normally use it to unlock the device and/or to verify your account just before you… Read more »
I’ve read a great book recently, Soft Skills: The software developer’s life manual by John Sonmez. I borrowed that book to a friend, and somehow he stumbled on a blog course that covers some of the topics covered in the book. Since I enjoyed the book, I decided to give it… Read more »
I’ve read a great book recently. Algorithms Fourth Edition by Robert Sedgewick and Kevin Wayne. This is a great book that reminded me of my college days when I was listening to my Algorithms and Data Structures. This book is written as a text-book, and is very technical. So if… 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 »
With iPhone 6s came the 3D touch, and with it we got a few more options to interact with the users. In this short blog post we’ll examine one of those options called ‘Application Shortcuts’, or sometimes called ‘Home Screen Quick Actions’, we’ll call them application shortcuts, because it’s shorter….

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 »
