Building a Foundation with Swift

Now that we have had a short tour of Xcode, it is time to start learning about Swift. Remember, if you are new to programming, things will be very different for you, so take your time. The essential skills that you learn here will set you up with a solid foundation in iOS development. If you have previous programming experience, you should still review this chapter, as it can only enhance your programming skills and act as a refresher for you.

On June 2, 2014, Apple changed the game for iOS development, because this was the day they announced Swift to the world. With this announcement, everybody was put on an even playing field, because they had to learn a new programming language. Swift has brought a more modern approach to developing apps and has seen a massive influx of new developers of all ages wanting to build iOS apps. However, enough about...

I'm into about 5 chapters. The examples are great; easy to follow and the explanations are right on. The author goes at just the right pace. He took the right approach. He teaches Swift as well as iOS 12. This book is well worth the money. I am now about to start the iOS 12 section building apps. I will updated more as I continue. Chapters are clear and easy to understand. Generally each chapter can be completed in about 2 hours or less. I'm looking forward to adding to this review once I complete this book.

I'm an experienced (5+ years, 6 monetized, published apps) Android developer who bought this book to add iOS to my portfolio. I bought the eBook on sale directly from Packt for $10, and man am I glad I didn't spend more than that.First, the good bits.1. Clean codeThis book has so much potential. It subtly teaches the use of design patterns (it doesn't specifically name them, but if you're already an experienced coder, you'll recognize them) and good programming practices, such as "separation of concerns", "D.R.Y. (don't repeat yourself), and S.O.L.I.D principles in general. I like that it's not just teaching you how to code swift, but how to write clean code, period. The end of some chapters even have you go back and refactor.2. ThoroughThe book's project, "Let's Eat", is an Open Table/Yelp style app that brings you from the basics of Swift to advanced topics not usually explored in a beginners "learn to code" book such as APIs (specifically JSON), store submission, and iMessages and Siri integration. If you take your time and carefully learn each chapter, you will be equipped to start your own project with plenty of sample code to reference from.Now the bad: TYPOS, TYPOS, TYPOS.There are so many typos that it unfortunately undoes all of the positive points I've listed above. Because I'm an experienced coder in Java/Kotlin, and patient enough to explore Apple's Swift documentation when in doubt, I was able to make it to the end of the book. But it was definitely a testament to my determination more than anything.TLDR:This book has so much potential but thanks to project-breaking typos, missing code and more, I would NOT recommend this book to anyone who is coding Swift for the first time. Because of the advanced topics it covers towards the end, it might be ok as a second book after a using one with better editing as your introduction to Swift. That way you can recognize the typos (admittedly, some are obvious) and have a bit more confidence when the sample code doesn't compile even though you copied it word-for-word.Do not pay more than $10 for this book.

Started the LetsEat tutorial. It worked for a couple of chapters then the app started crashing. Inspection revealed there appear to be some code missing. Have requested support from Packt. After a couple of weeks, nothing from Packt. Advise new iOS programmers not to purchase the book as the app will require some study and a bit of luck to make work.

My review simply echos W. Baer's review... Up to Chapter 10 - great, after that, I had to stop. I contacted Packt and although they did reply it didn't help me so regretfully I had to abandon this book. Shame as it looks like it had everything I was looking for.
