[swift-evolution] [Pitch] Typed throws

[Adrian Zubarev]

Wouldn’t that mean that you couldn’t use your Swift library in Objective-C anymore, at least the error type as an NSError?

I thought it was going to be any one subtype of Error, be it a struct, an enum, or a protocol existential, or Error itself.

Imho we should remove the restriction that you can only throw Error-conforming types if typed throws are added:
It's a compatibility feature, and if you manually declare what can be thrown, you should be allowed to break with Objective-C.

As Error has no requirements at all, it looks like harassment, as its whole magic is neither visible nor necessary.
