Swift ReactiveCocoa issue when using rac_textSignal()

Question

Hi guys I am trying to test the example of "Observing text edits" from https://github.com/ReactiveCocoa/ReactiveCocoa

However when i try to use rac_textSignal() signal I got an error saying "Value of type UITextField has no member "rac_textSignal"

Can someone please point out what I am doing wrong here? Thank you so much.

class ViewController: UIViewController {

    @IBOutlet var textField: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        let searchStrings = textField.rac_textSignal()
    }
}

无论您在哪里使用 ReactiveCocoa，都可以导入它。
