I completely forgot about new logging system that works since the iOS 10, but then I noticed this article that describes this system with some thoughts on why we'd want to use it. So I think we have to try to stop using NSLog and print statements, as well as some kind of logging libs such as CocoaLumberjack.

It's the most popular question since the release of Xcode 10 - ”Where's the Library?”.
So this article describes some tips on how to simplify the process of working with new library popup.

The most useful tip is you need to hold the Option (⌥) key to keep the popup visible until you close it yourself.

Implementing the Coordinator pattern using UIResponder. 🤔

”With this approach, you can:
1. Call a Coordinator's method from anywhere: view controller, view, button's event handler, table/collection view cell, UIAlertAction etc.
2. That call will be passed up the responder chain until it reaches some Coordinator instance which overrides that method.”
