Overview of this book

Swift Language is now more powerful than ever; it has introduced new ways to solve old problems and has gone on to become one of the fastest growing popular languages. It is now a de-facto choice for iOS developers and it powers most of the newly released and popular apps. This practical guide will help you to begin your journey with Swift programming through learning how to build iOS apps. You will learn all about basic variables, if clauses, functions, loops, and other core concepts; then structures, classes, and inheritance will be discussed. Next, you’ll dive into developing a weather app that consumes data from the internet and presents information to the user. The final project is more complex, involving creating an Instagram like app that integrates different external libraries. The app also uses CocoaPods as its package dependency manager, to give you a cutting-edge tool to add to your skillset. By the end of the book, you will have learned how to model real-world apps in Swift.

Weather forecast API

There are many web services which provide weather forecasts. Some of them are paid, while some of them are free. To learn how to consume one, we can use a free access one and later, when we are sure what exactly we need, we can decide to use the best provider on the internet.

API stands for Application Public Interface. In terms of the web, this is a set of functions which are hosted and can be accessed by different users through the global network. These functions provide certain data or they can transform data.

For example, there could be a mathematical API which implements different mathematical functions. To consume it, we should know the server address and the name of the functions...
