What's the advantage of #selector update in Swift 2.3?

Question

I can\'t see a problem with just writing the method name as a string. Im just curious as to why this is better?

Answer 1

“Before Swift 2.2, selectors were string literals and prone to error because we, as humans invented, and still contribute to typos whenever given the chance to write something without autocomplete.”
