Why I Created Learn Swift with Bob

As a developer whose first programming language is Swift, I've taken online courses from major platforms. However, I have been frustrated by a lack of detailed explanation from instructors. They tend to focus on final products, thus missing out the fundamentals. I was confused by which design principles to follow, and why. Soon after I've been blogging for the last 5 months, I've discovered this isn't the only problem of mine. I've received hundreds of emails and questions regarding how to write code that does not violate principles such as DRY, modularity, and readability. As a result, I've decided to create this course dedicated for my younger self. I believe it all comes down to the fundamentals which I lacked in the beginning.

Course Overview

There are 10 chapters in this course. From Chapter 1 to 4, you will get a firm understanding of both Intro to Functional, and protocol, and Object Oriented Programming. In Chapter 5, you will fully understand how objects are created and removed. In Chapter 6 and 7, you will learn how to create value oriented swift code along with protocol generics and enums. In the last chapter, you will acquire various advanced and hidden tips about the Swift Programming Language.


This course is designed for Swift intermediates. So, I won't cover the basics. You may visit the lecture notes and go to prerequisites. You will find a list of items you are expected to know. There is a YouTube video for each concept, so if you ever get stuck, you can always learn and come back. In a nutshell, you should be already be familiar with switch statement, conditional statement, basic operators, functions, and basic object oriented programming. 


Do you know why Swift engineers have implemented optionals? Do you know what completion handlers and how to design one for your project? Do you know retain cycle within closures and delegates? Do you know the difference between autoclosures, trailing closures, and @escaping closures? Do you know how to create custom operators. Do you truly understand the statement, "Swift is a protocol oriented programming language", and know how to use default protocols such as Equatable, Comparable, Sequence, and Iterator Protocol. Lastly, do you know the difference between normal and recursive enums? If you can't answer all of these questions, I recommend you to take this course and start learning with me.
