100 Days of SwiftUI

So would I recommend this tutorial for people? ABSOLUTELY! I was literally able to release my first app with (pretty much) only doing this tutorial alone. Everything I did I took from a lesson in 100 Days of Swift. My layout is created similar to 7 Swifty Words, the majority of my flags are created using Core Graphics, I use tableviews, CollectionViews, UIAlertControllers, UIActivityController, animation, Timers, importing images, resizing images, ScrollViews, UserDefaults, and the normal programming stuff that Swift offers. I literally learned ALL of those things from Hacking With Swift. If I can do it, you can too!

For beginners to swift, I would highly recommend HWS. I've been working on a new project on the side incorporating many of the new concepts I've been learning so far which has really been helping me retain the information.

I'll vouch for Hacking with Swift. I came from an Objective-C iOS background (EDIT: also CS degree and previous non-iOS dev work) and found that Paul Hudson's stuff was a good way to transition into the Swift side of things.

I'll put it to you this way -- I've gone through very expensive Swift training (corporate training is a big money business and it always shocks me) and the contents of this very expensive training have been almost identical to what is available for free on Hacking with Swift. I would even go so far as to say I've seen, in some cases, more detail on HwS than in my other training.

Very clear explanations, and explained so that even people who are not very experienced with programming, and havent been doing it for decades, can understand what's going on.

Hacking with Swift is an amazing, practical approach to iOS development, and I believe it is still free (though supporting them is always encouraged, and I believe you get convenience out of it, like a PDF version of their material or something like that among other things). I recommend going through their projects. Once finished, you will be in a good place to branch off, they offer several books that specialize in various aspects of Swift.

HWS introduced me to a way of learning even though I knew how to code. Forget the theory, do practical things first and you'll see the theory fall into place.

Hacking With Swift - very good step by step but no videos. Offers 2 ways to learn ie learning via building apps or swift language first.

These online tutorials are a great way to learn the basics of Swift and start building your first few projects with step-by-step instructions. Paul Hudson, the author, writes in a way thats easy to understand, especially if youre new to programming. These tutorials are designed to be used on a Mac with Xcode. Highly recommended and theyre free!
