How to split a [String] into rows?

I'm using a UITextView to add some values into an array.

I'd like to separate the text from the UITextView into single items if they have a newline (\n) or a comma (,) between them.

var values = self.textLabel.text.componentsSeparatedByString("\n")
for item in values {
    if item != "" {
        cellDataSet.insert([item, false], atIndex: 0)
    }
}

If you want to separate a String on multiple tokens, use componentsSeparatedByCharactersInSet(_:)

Example:

let text = "This is, some, text; With multiple | seperators"
let separators = NSCharacterSet(charactersInString: ",;|")
let values = text.componentsSeparatedByCharactersInSet(separators)

You can use the globally available split function to do the same.

let stringToSplit = "Words,Separated\nBy,Comma,Or\nNewline"
let outputArray = split(stringToSplit) {$0 == "," || $0 == "\n"}
