Happy too! So my main resource is Hacking With Swift (https://www.hackingwithswift.com), specifically the 100 days of SwiftUI Course. It takes you over Swift and SwiftUI. I've paired this with the official Swift site (https://www.swift.org) so I can dig into the language more, and Apple Documentation where appropriate to get used to using the tools.
In terms of finding it, it was a bit of a shot in the dark. I did some poking around and this popped up the most, specifically because I was looking for iOS specific materials. I'm sure if you want to make cross platform apps there's probably a whole host of great resources!
Happy to speak on that! I mostly wanted to dig into something I hadn't done before, with a whole new set of tools to learn. In this case, I had been super interested lately in the Apple ecosystem/platform. I'd spent some of my career in .NET/Windows land and got to see a bunch of stuff there and how it all worked, so I figured why not try out what Apple has to offer.
I also felt like since I have no real intent to try and turn what I'm learning into something that makes money, I could go a little crazy/niche and dig in.
This all being said, If someone asked me about making an app as something they want to release/make money off/turn into a company I'd fully be pointing them at tooling like React Native.
