An Xcode 9 project written in Swift 4 code to communicate with a wearable heart rate monitor using the Core Bluetooth framework.
In the tutorial for this code, I'll explain the essential concepts behind Bluetooth® technology, show you how getting proficient in Bluetooth® software development presents you with a tremendous career opportunity, remind you that you can't distribute an app that uses Bluetooth® without determining if you need to go through "qualification," provide you with an overview of Apple's Core Bluetooth framework, and finally, walk you through the development of an iOS app in Swift 4 that monitors a person's heart rate via Core Bluetooth and a Bluetooth® heart rate monitor -- a "wearable" -- device. Here’s what my app looks like when scanning for a heart rate monitor (HRM), and what it looks like when connected to and reading heart rate data from an HRM -- all wirelessly:
