Split lines without omitting empty lines in Swift

How can I split lines in Swift (4+) without omitting the empty rows?

Both "1\n2\n\n3".split { $0.isNewline } and "1\n2\n\n3".split(separator: "\n") give me only three items while I need 4 with the third one beiing empty

You could try: 

"1\n2\n\n3".components(separatedBy: "\n")

Or more concise and readable, as suggested by Leo Dabus:

"1\n2\n\n3".components(separatedBy: .newlines)

These both result in: ["1", "2", "", "3"]

split has omittingEmptySubsequences parameter just for that.

By default it's true. So just set it to false:

"1\n2\n\n3".split(omittingEmptySubsequences: false) { $0.isNewline }
