Swift iOS Development From Scratch July 10, 2014
Swift is very, very new. As such, there aren't a lot of tutorials out there for people who have done literally zero iOS development in the past. I've only been tinkering around with it for a few days, but there's not a lot of information out there for starting from zero.
Here's the best way to start from scratch:
1: Download XCode 6 Beta
I had XCode 5, but didn't realize you had to get XCode 6 BETA to have access to the Swift Programming language (like I said, I'm brand new to this). You can download it here (warning: it's a big-ass download).
2: Familiarize Yourself with XCode
The tutorials I've found seem to be mostly for people that are already familiar with XCode. I was not. If you skim over this tutorial, it will at least give you an idea of where things are. This particular post is for an old version of XCode, but it should be enough to help.
3: Follow This Guy's Tutorials
I came across this guide that is (mostly) for beginners. He does take a few assumptions (like assuming you've opened up XCode once in your life), but it's great for the most part.
