If we’re going to build a Bluetooth app for WatchOS and iOS, we need at least one additional primitive to be available – a 24-bit unsigned integer. Since Swift doesn’t provide that, we’ll just have to create it ourselves. This post will dive into how to create a custom numeric data type in Swift (and how to overcome some limits of the platform in the process).

The world of software development is changing rapidly. With Google’s latest announcement, part of how we deploy systems is getting ready to change for the better for nearly half of all companies. Are your teams ready for the challenge?

If we’re going to build a Blutooth-enabled application, the first step is understanding the basics of how data is provided to clients. In this post, I’ll explore some basic terminology and concepts. We’ll then look at how the data is structured so that we can interpret it in our application.

I decided that it was time to improve the integration between my treadmill and my watch. First, I upgraded my treadmill with a smart device that provides standardized services using Bluetooth Low Energy. Next, I created an application that integrated everything together. After that, I began this series to make it easier for you to build a Bluetooth-integrated application in Swift.

Minimizing network activity improves your build times, speeds up builds, and reduces costs. With ARC, you rely on multiple Actions steps in your workflow. What if you could avoid needing to download your most frequently used Actions? This post walks you through creating images with an Actions archive cache to eliminate those downloads.
