I think this is a good course to quickly experience iOS overall. It helped me figure out what kind of flow and what kind of thoughts I should have while studying in the future. However, there were some difficulties I had while taking the course, so please refer to it for future students. - The comments in the attached code blocks are brief, so it is difficult to review them with just the code blocks. So I copied the explanations in the video and used them for review. (It took some time because I paused the video and wrote it down;) - The code explanations are somewhat lacking. Even if you complete the course by project, you cannot learn everything at once. Since I just finished the course, I plan to review it several times. - It is a shame that there are no solution videos for the challenge problems. I understand that students are encouraged to solve them on their own, but I think that solution videos are necessary in terms of the completeness of the course. Then I will go review :)
