When I first started learning Swift, I really struggled. I remember going to other lectures and studying on my own, always wondering, "Why is it like this?" since they didn't explain it in detail. Then I happened to see a 2-month boot camp course at Inflearn, and I paid for the course with the money I saved up from my part-time job. It was a lot of money for me, but I got more than its worth. Now, I can read everything, like official documents or blog posts written by other people, and it's still so amazing. I just did what I was told. If you've been lost in other places like me about Swift, or if you're just starting out, I definitely recommend it.
