Hello World! Build Your First App Using Swift

By now you should have installed Xcode 7 and some understandings of Swift language. If you haven't done so, check out the previous chapter about what you need to begin iOS programming. We'll use Xcode 7.0 (or up) to work on all exercises in this book. You may have heard of the "Hello World" program if you have read any programming book before. Hello World is a program for the first-time programmer to create. It's a very simple program that outputs "Hello, World" on the screen of a device.

Getting Started with Xcode 7 Development

So you want to create your own app? That's great! Creating an app is a fun and rewarding experience. But before we begin to dive into iOS programming, let's first go through the tools you need to build an app.

Beginning iOS 9 Programming with Swift

Last year, Apple brought us Swift, a brand new programming language for both iOS and OS X. When it was first announced, just like many iOS developers, I was thrilled. Advertised as a fast and safe language, Swift has now grown to one of the most popular programming languages. As expected, the company introduced Swift 2 at WWDC this year. In this site, I will give you an introduction to Swift 2, discuss some of the new features in iOS 9, and most importantly, show you how to build a real world app from scratch.
