This Stanford course has everything you need to start iOS Development. Every lesson is well explained with code demos and how Paul Hegarty explains the concepts of Swift and UIKit is amazing.

These are my solutions for all the assignments for the CS193p-2017-2018 course using UIKit, Storyboard, Swift, and Xcode. If you are taking this course on your own, as I did, I hope this helps you.
