As a non-major developer, I always felt like I lacked basic knowledge about the technology when learning new technologies, even in the languages I use. It was the same when I came across iOS, and it was even more difficult because the differences between different languages felt greater than the similarities. Then I was recommended this course and took it. It was quite a lot to keep up with while working at a company, but I learned a lot of new things as I listened to the lecture. I also thought that it would have been more familiar to someone who was familiar with computer architecture, memory, and the C language. It was interesting to study a language from a perspective I had never encountered before, and it was a time to learn more deeply about the language called Swift. I wondered how they studied so much and created this material. There was so much prepared content. I have only just finished the grammar lecture, so I am not sure how much of what I learned will help me. I think I will feel it in the app creation lecture that follows. What is clear is that by studying one language from the beginning in this way, I gained confidence that I would be able to learn other languages quickly. We have a live session every week, so you explain the parts that I lack, and you test the parts that I might forget every week, and since we all check the progress chart together, I feel like I have to work hard even if I am a little behind. This is a lecture that puts a lot of effort into it, and I want to listen to the instructor's other lectures and the next lecture.
