Swift, Youy, and Objectivec Runtime Hacking

There are certainly benefits to having the safe, ah, the safety of swift. But sometimes you want the ability to go to sort of be in unsafe territory. I think what every kind of more higher levelapi needs is an scap patch. And even with swift as a language, you do have a lot of escape patches. For example, you can use force on wrapping if you don't want to have to deal with optionals. If we imagine a future where swift u eye will be the only u i framework, then what will be the escape hatch? We will need something where we can customize.
