"I strongly recommend this course to anyone who wants to learn the fundamentals thoroughly." Despite being a computer science major, I didn't pay much attention in class, which left me with weak fundamentals. After deciding to pursue a career as an iOS developer, I felt the need for in-depth learning and found this course. Although the price was somewhat burdensome compared to other Inflearn courses, I was convinced that it would be a worthwhile investment if I could gain proper knowledge, so I decided to enroll. The greatest strength of this course is that it goes beyond simply memorizing syntax and helps you understand the fundamental principles. In particular, the instructor explains memory structure, CPU operation principles, and more in detail using diagrams. Thanks to this, the concepts became clearly established in my mind. I was able to learn core concepts that felt difficult—such as classes, structs, ARC, and asynchronous processing, which are common interview questions—in a way that "spoon-feeds" you. I was able to cover in-depth content across both Swift and iOS development in general. Beyond the learning itself, the active community management was a great help. I could receive immediate answers to my questions, so my learning flow was never interrupted. I was able to hear stories and know-how from people who had already successfully found employment, which gave me confidence and motivation for my career preparation. I highly recommend this course to computer science majors with weak fundamentals or anyone who wants to build a solid foundation!
