Ranges

I wondered aloud, in a previous post, about the differences in writing a range as

        ForEach(1..<21) {
            Text(String($0))
        }

versus

        ForEach(1...20) {
            Text(String($0))
        }

And that’s been answered in in one of the Day 34 articles. It sounds like older versions of Swift might not have allowed the second version.
