One of the main reasons I wanted a Macbook was to build applications for iOS. In 2014, I watched many lectures from Stanford University's Developing iOS 7 Apps series ^1. The series covered Object-Oriented Objective-C. I was 11-12 at the time when I was watching the course. I cannot recall much of the material today, nor can I attest to how much I retained from that lecture series.
CS193p left me with a sense of curiosity about coding. When I did get a Macbook, some time after I watched the course online, the notion of actually building an application using Xcode -- the most modern version of which, at the time, was Xcode 5! -- wasn't interesting. But I still knew I wanted to code, although I hadn't quite found "my thing" yet.
Flash forward years later and I found myself in love with programming, particularly Python and the web. CS193p was both exactly for what I was looking and not quite right for me at the same time: a demonstration of what was possible with programming, but that was missing the same allure that I found in Python later in my coding journey.
I still vividly remember the introduction scene to the course showing Stanford University. That, the name of the course, and how I watched with intrigue and curiosity are all deep-rooted memories.
