Ha! I was right yesterday: The review of closures was part of the 15th day!

I liked on this day, that Paul went a bit more into the details of access control and typecasting.

Also, I changed some legacy code yesterday to use Void instead of () as return-type of a closure. I saw that in Paul's code and it reminded me, that at my job, we should follow a code styleguide. Those () always confused me, but it's nice to be aware of a better alternative.

Hopefully I will write some SwiftUI-code tomorrow. I'm getting exited! 🤓🤓🤓🤓
