How to get the lines in a string as an array
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")
}
}Available from iOS 8.0
