Design Patterns in Swift: A different approach to understanding design patterns.

Hello All! I am Vamshi, author of this book: Design Patterns - I came across this term for the first time in my life in a job interview (mind you, I was almost two years into iOS Development then). I got back home and googled about them. It was embarrassing and interesting at the same time, as I found out that I had been using a few of those patterns without actually realising that I was doing so. I forgot about that incident after several days and got back to my work. Fast forward two years, I was back at job searching and this time I decided to learn in depth about design patterns. As a seasoned iOS Developer, I was initially looking to learn the concepts through examples coded in Swift language. Surprisingly, I could not find a single book or blog discussing design patterns in detail in the Swift language. There are tons of books and blogs discussing them in Java, C#, PHP, etc. For someone who codes in Swift, it only takes a little effort to understand Java. So, I started learning the design patterns from different sources available on the Internet through Java examples. For practice, I started putting up a few examples in Swift for each of the design patterns. Personally, cricket is something that I understand in and out. I can almost relate anything under the sun to a situation in cricket (okay, that’s a bit of an exaggeration). So, I decided, instead of using different contexts for each of the design pattern examples, I would be using cricketing terms for all the examples I would be coding. I believe cricket is a very simple game, and even for those who do not follow the game, it should not be a big effort to relate to the cricketing terms.
