Howdy – I’m Trevor, Adafruit’s Lead iOS Developer and I’m currently learning SwiftUI. SwiftUI is Apple’s newest programming language that makes complex UI very simple to implement. While using SwiftUI I’ve noticed that developing your UI is significantly faster – even faster than using Storyboards! I’ve decided to recreate one of my first iOS apps I’ve made prior using SwiftUI and it was fun and easy to put together.

The app was a pedometer app. Nothing special. This app uses the CoreMotion library and URLSession to make network calls to Adafruit IO and stores the amount of steps and calories accumulated daily.

Adafruit IO is a platform designed (by us!) to display, respond, and interact with your project’s data. We also keep your data private (data feeds are private by default) and secure (we will never sell or give this data away to another company) for you. It’s the internet of things – for everyone!

As I started getting more familiar with SwiftUI, I’ve decided to really lean into its benefits. Instead of create UI that knew I can put together easily, I wanted to make some thing more dynamic.

I went from creating this..

To this!

One thing that I’ve noticed that more complex tasks don’t have good example code yet. Rather than just searching stack overflow for how to accomplish a task, you might have to read the Apple docs and figure out how to put together multiple pieces that have never been written about before. They’re just aren’t a lot of examples for how to do things yet, and there’s a lot of new terminology to learn just to be able to google about what’s going on. I’lll be sure to create more blog posts like this in the future.
