Marc is a good friend of mine. He has a lot of qualities and I even thanked him in my book for all the support he provided me. That being said, he’s still using a super-small iPhone 5S and when I sent him the first build of this project, I forgot to handle the keyboard and it was impossible for him to log into the application. Fortunately for the both of us, handling keyboard-related notifications in an iOS application is super easy. Let’s see how Swift and ReactiveSwift can make it even easier.
