Woah! NSClassFromString() lookups work with native Swift classes. /via @mjtsai http://mjtsai.com/blog/2015/07/23/dynamic-swift/#comment-2482853 … (David Koretzky)

@owensd @mjtsai I don't know how I feel about using such a Factory in Swift, kinda destroys the static-ness which we love...

@Kametrixom You still get to cast the return value from NSClassFromString() to make sure it’s what you think it is…
Kametrixom ‏@Kametrixom 23 Jul 2015

@mjtsai True, but the initializing with a String is very ugly and you have to watch typos. Generics are more to my liking
David Owens II ‏@owensd 23 Jul 2015

@Kametrixom @mjtsai they solve different problems. And the typo will fail. You need to be using as? instead of as!, no safety loss.

@owensd @mjtsai I get it, but maybe an enum with an associated class for each case would work too but be compile-time fail-proof?

@Kametrixom @owensd The class may not even exist at compile time.
