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.

Inheritance

Inheritance is a mechanism that helps developers through the process of implementing complex hierarchical data structures. All inherited features become part of the new class. To put it simply, a class can inherit properties and methods from another class. The class which is inherited is called a parent class or super class. The new class which inherits another class is called a child class.

The inheritance is applicable to classes only.

Each class which inherits from another class can provide a specific implementation of the inherited features. All other functions, properties, subscripts, and so on, can be accessed from the child class.

Base class

Every class which doesn't have a super class is called a base...
