Swift doesn't support exceptions AFAIK. It supports weird error handling
that looks similar to exceptions, but is really just a standard return.
i.e. this:

do

   try someFunctionThatErrors(arg)
}
catch(Exception ex)
{
   // handle ex
}

really compiles like this:

var _err : Error?
someFunctionThatErrors(arg, &_err)
if(_err != nil)
{
   let ex = _err!.exception
}

Exactly and you're not supposed to catch exceptions in Objective-C. It's 
more like Errors in D.
