What I learned from doing the Advent of Code 2019

I did many tutorials with Swift before and the experience has always been guided. Of course, it has to be like this, nothing wrong with the tutorials. It is just that I never really did put into practice what I was learning. The advent of code has allowed me to approach and deal with problems. I was almost about to say real-world problems, but really to rescue Santa cannot be considered a real-world problem, can it?
