However their exceptions work in a more RC friendly way.
Swift doesn't support exceptions. And in Objective-C exceptions
are like Errors in D. They should not be caught and the program
should terminate.
The error handling support that was added in Swift 2.0 is
syntax sugar for the Objective-C pattern to use NSError out
parameters for error handling.
Hence why I mentioned they are more RC friendly.
Swift, because it doesn't have them.
Objective-C, because termination is the only option so no need to
worry about preserving counters.
I was typing on the phone, so didn't want to provide the full
explanation.
