[swift-evolution] [Pitch] Introduce continue to switch statements

[Taras Zakharko]

I’d love to see goto in Swift, but on the other hand, do {} with labels have so far been sufficient for any practical problem I encountered so far. Goto is much more useful in languages like C, which lack nested functions and other abstraction mechanisms. 

Of course, I wouldn’t try to write a high-performance interpreter in Swift any time soon.
