jungmin82's honest review, iOS App Monetization Start, Swift Grammar Master [Beginner] course

I started without any burden since it was free, and I completed the entire course. I watched each lecture while practicing examples on the app, read explanations, and reviewed... There was a time I almost gave up on Swift because I couldn't understand optionals, but through this course I learned exactly why they're used from the ground up. I feel somewhat guilty for completing it all for free, so I'm leaving this review!! Thank you~!!
