It's too late now It's a lecture from 3 years ago. In the meantime, Swift and XCode have been updated continuously, and there are many parts that do not match this lecture. I appreciate Hangulling's efforts, but the Korean subtitles did not come out until the end, so only 10 lectures out of 17 lectures were translated. Although it's an old lecture, the core of iOS and Swift itself has not changed, so I think it's worth watching once. Thank you to the Hangulling team. This lecture is from 2016, and additional materials from the first half/second half of 2017 have been uploaded to the YouTube below. The PPT slides and source code are also on Google Drive and GitHub. Those who have taken the lecture or will take it, please refer to it. https://www.youtube.com/user/MichelDeiman/playlists
