Errors should be Just Another Value, so the difference between untyped errors and typed errors is the same as the difference between just using Any for every parameter and return value, and using actual types. You can use Any for everything, and it can even be totally safe if you use as? correctly, but it's obvious why no one does that. It's not obvious to me why people are fine with that situation for errors - again, the catch-all handler issue mentioned above, and the bizarre special-casing of NSError. |
