How to get the lines in a string as an array

Swift version: 5.0

Paul Hudson    @twostraws   

Swift’s strings have their lines separated by the \n character, which is a line break on Unix operating systems. Using that plus the components(separatedBy:) method, you can get an array of all the lines in a string like this:

let lines = str.components(separatedBy: "\n")

If you intend to use that regularly, consider making an extension on String like this one:

extension String {
    var lines: [String] {
        return self.components(separatedBy: "\n")
    }
}
