In this chapter, you will look at using the new programming language from Apple called Swift. It is a new language created by Apple and has very powerful features to perform a variety of tasks and is now open source. Apple released it, and it has grown so fast that in the months and years to come, it will be the de facto standard for coding using Apple devices. You will see how Swift works with iOS, Xcode, and SQLite.

It has been an extraordinary journey since Swift was announced at the WWDC 2014 in San Francisco. In 2015, Apple announced that Swift would be open source. The language itself allows you to write high-level code and even low-level code with ease. It is a culmination of languages, such as Python, C, and Objective-C, making it faster and easier, and it's available on a number of platforms.

Can you imagine what is going to happen in the next few years? Design patterns and skills are developing at a fast rate, and applications will be rewritten...
