Explore Swift's object-oriented concepts Become familiar with built-in Swift types Dive deep into Swift objects, protocols, and generics Tour the lifecycle of an Xcode project Learn how nibs are loaded Understand Cocoa's event-driven design Communicate with C and Objective-C Once you master the fundamentals, you'll be ready to tackle the details of iOS app development with author Matt Neuburg's companion guide, Programming iOS 13.
Swift does not seem to have a lot of options when it comes to books, especially compared to Java or Python. So this is basically the Swift book to read (along with the second book, which I have not finished yet). Luckily it's also really good. The author's intent was to write a book to be read all the way through and then used as a reference. It has served both purposes well for me. Of course, there are some things it does not cover. Personally I wish he would write a book on SwiftUI.
Provide good examples of swift from fundamental to in-depth knowledge in first half of the book. The other half is about how to use xcode, it's good to know but will be more better to watch youtube tutorials.
