Back in the early 90s, when the primary language that I developed in was C, I had numerous custom libraries that contained functionality that was not a part of the standard C library. I found these libraries extremely useful because I tended to use the functionality they provided in most of my projects. This functionality included things such as converting the first letter of a string to uppercase or converting a double value to a currency string (two digits after the decimal point and a currency symbol). Having libraries such as these is extremely useful because there is always functionality that we find useful that is not included in the standard library of the language we are developing in. I usually implemented this extra functionality in C with global functions. In more modern object-oriented languages, we can implement this functionality by subclassing the class...

Overview of this book
Swift has become the number one language used in iOS and macOS development. The Swift standard library is developed using protocol-oriented programming techniques, generics, and first-class value semantics; therefore, every Swift developer should understand these powerful concepts and how to take advantage of them in their application design.
This book will help you understand the differences between object-oriented programming and protocol-oriented programming. It will demonstrate how to work with protocol-oriented programming using real-world use cases. You will gain a solid knowledge of the various types that can be used in Swift and the differences between value and reference types. You will be taught how protocol-oriented programming techniques can be used to develop very flexible and easy-to-maintain code.
By the end of the book, you will have a thorough understanding of protocol-oriented programming and how to utilize it to build powerful and practical applications.
