| // We can't use `Character` or `String` ranges directly because they aren't countable | |
| // Create a countable range of ASCII values instead | |
| let range = UInt8(ascii: "a")...UInt8(ascii: "z") // CountableClosedRange<UInt8> | |
| // Convert ASCII codes into Character values | |
| range.map { Character(UnicodeScalar($0)) } // Array<Character> | |
| // → ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"] |
