"In the early 2000s, when I first set foot in this industry, bookstores were filled with nothing but books preaching 'principles.' While you actually need to see the forest in the field, those books were busy talking about the cell division of tree bark. In that state, I was dropped into the middle of the deserts in Qatar, the UAE, and Saudi Arabia, learning HVAC the hard way by 'hitting the ground running.' (The sweat I shed back then could have probably created an oasis.) Later, when I moved to a data center and sat as an interviewer, I was surprised to find that many applicants still couldn't see the 'forest,' just like I couldn't 10 years ago. Out of frustration, I thought, 'I might as well set the stage myself,' and that's how I created this course. This is a 'condensed practical summary' of everything I've realized through 17 years of hands-on experience. Don't struggle as I did; use this course as a 'cheat code' to level up with ease. I always welcome your curiosity. The Q&A board and my inbox are on 'infinite standby,' open 24 hours a day."

When learning Swift, the iOS programming language, it can be confusing when multiple concepts appear all at once. That's why I created this course with the principle that "when understanding a new concept, only previously learned concepts should be used." So this course is meticulously designed with a sequential structure between concepts, where only one new concept appears at each stage, and no other unfamiliar concepts appear at all. One concept per minute, 180 concepts total. From the basics of variables and constants to understanding memory structure from a CS perspective, and even the latest syntax for asynchronous processing. In 3 hours, you'll learn 180 core concepts in the designed order.
