-1 I agree with this and doing something a specific number of  times without accessing the iteration counter is an edge case in my experience. Creating another syntax to save 4 characters for an edge case is a poor benefit/complexity tradeoff.  Ignoring with an underscore is universal in Swift and, to me at least, expressive and intuitive.
