Coding is my passion, is it yours too ?

Hello,

My name is Chathura Marasinghe and I'm a well seasoned Software Engineer with over 20 years of industry experience. Out of that 20 years, almost 15 years of it spent on developing iOS apps to tech companies from small Boston based startups to Silicon Valley giants. My coding experience expands from lower level C++ to Objective-C and the latest version of Swift (whichever is that). And from developing image processing libraries to contributing into highly scalable iOS apps with multi million lines of codes. At the moment, I work as a Senior Staff Engineer in Big tech (please see my LinkedIn profile for more) and lives in greater Boston area.

If you learn something new from my Blog or if you just like my writing style, please don't hesitate to drop a line in the comment section and I will do my best to reply as soon as possible. Thank you and hope you enjoy reading my blog posts !

Swift Protocol Oriented Programming for iOS Devs - 2

Naming your Protocols

This is the part 2 of the Swift Protocol Oriented Programming series, the first part was an introduction to Protocols compared to Java Interfaces and some of the basic characteristics of both compared in one-to-one manner. However as a developer, the more important questions are asked when and how we can use POP design pattern in our day to day coding.

Swift Protocol Oriented Programming for iOS Devs - 1

This is the first part of a multiple part series of Protocol Oriented Programming with Swift (Actually Only with Swift, if you know any other programming language which supports Protocol Oriented Programming, please be kind enough to comment below). Let's first try to understand what the heck is a Protocol in Swift/iOS App development context. May be we should start from somewhere most of us are familiar with, at least the people who are familiar with Java (if not, you are missing a lot), yes the most popular programming language in the world.
