Question

I want to convert it to an array, one array element p

Answer 1

For the record, Swift's Foundation CharacterSet can be used within split:

alternative 1

extension String {
    var lines: [String] {
        return split { String($0).rangeOfCharacter(from: .newlines) != nil }.map(String.init)
    }
}

alternative 2

extension String {
    var lines: [String] {
        return split { CharacterSet.newlines.contains($0.unicodeScalars.first!) }.map(String.init)
    }
}
