Hi @uuttff8, thanks a lot for your PR!
As soon as possible I will review in detail your changes, quickly looking I didn’t see any problem.

Thanks to bring the dark mode to the project!

I really appreciated your effort!

So far, I do not have any comments to do here. Just say a huge Thank You for your time giving some love to the code and bringing support to Swift 5, what I couldn't stop to do.
