Only you are going to tell yourself you cant do it For the newbie This book assumes you may have never programmed before. The book is also written for someone who may have programmed before but never using object-oriented programming(ooP)languages There are several Swift books out there, but all of these books assume you have programmed before and know OOP and computer logic. We wanted to write a book that takes readers from knowing little or nothing about computer programming and logic to being able to program in Swift. After all Swift is a native programming language for the iPhone, iPad, and mac Over the past six years, we have taught thousands of students at xcelMe com to be iPhone/iPad (iOS) developers. Many of our students have developed some of the most successful iOS apps in their category in the iTunes App Store. We have incorporated what we have learned in our first two courses, Introduction to Object-Oriented Programming and Logic and Swift for iPhone/iPad Developers into this book For the More Experienced Many developers who programmed years ago or programmed in a non-ooP language need a background in OOP and logic before they dive into Swift. This book is for you. We gently walk you through OOP and how it is used in ios development to help make you a successful ios developer. www.it-ebooks.info kii ntroduction How This book is organized You,'ll notice that we are all about successes in this book. We introduce the oop and logic concepts in playgrounds and then move those concepts to Xcode and Swift. Many students are visual learners or learn by doing. We use both techniques. We'll walk you through topics and concepts with visual examples and then take you through step-by-step examples that reinforce the concepts We often repeat topics in different chapters to reinforce what you have learned and apply these skills in new ways. This enables new programmers to reapply development skills and feel a sense of accomplishment as they progress. Don't worry if you feel you havent mastered a topic. Keep moving forward The formula for success Learning to program is an interactive process between your program and you. Just like learning to play an instrument, you have to practice. You must work through the examples and exercises in this book. Understanding the concept doesnt mean you know how to apply it and use it You will learn a lot from this book. You will learn a lot from working through the exercises in this book. However, you will really learn when you debug your programs. Spending time walking through your code and trying to find out why it is not working the way you want is an unparalleled learning process. The downside of debugging is that a new developer can find it frustrating If you have never wanted to throw your computer out the window, you will. You will question why you are doing this and whether you are smart enough to solve the problem. Programming is humbling, even for the most experienced developer Like a musician, the more you practice, the better you get. By practicing, we mean programming You can do some amazing things as a programmer. The world is your oyster. Seeing your app in the iTunes App Store is one of the most satisfying accomplishments. However, there is a price, and that price is time spent coding and learning Having taught many students to become ios developers, we have put together a formula for what makes students successful. here is our formula for success: Believe you can do it. You'l be the only one who says you cant do this So, don't tell yourself that Work through all the examples and exercises in this book Code, code, and keep coding. The more you code, the better you'll get Be patient with yourself. If you were fortunate enough to have been a 4.0 student who could memorize material just by reading it, this will not happen with Swift coding. You are going to have to spend time coding You learn by reading this book. You really learn by debugging your code Use the free xcelMe com webinars and You tube videos explained at the end of this introduction. The free live and recorded training videos will be invaluable in quickly becoming a successful ios developer Don' t give up www.it-ebooks.info Introduction xxiii The Development Technology Stack We will walk you through the development process for your iOS apps and what technology you need. However, briefly looking at all the technology pieces together is helpful. these are the key ioS development technologies you will need to know in order to build a successful app and get it on the App Store Apple's developer website ■ iTunes connect ■ Xcode Swift Object-oriented programming and logic Debugging ■ Performance tuning We know this is a lot of technology. Don't worry, we will go through it, and you will become comfortable using it Required Software, Materials, and Equipment One of the great things about developing iOS apps is that everything you need to develop your app is free Xcode Swift ■OSX10.10 Yosemite Integrated development environment iPhone and iPad simulators All you need to get started is a mac and knowledge of where to download everything.
