Sending Data From Your App to Apple Watch Using WCSession

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 »

Creating a Temperature Sensor for iOS Using BLE and Arduino

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 »

Binary Search Array Extension in Swift

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 »
