Swift 4 version

override func viewDidLoad() {
    super.viewDidLoad()

    pickerView.dataSource = self
    pickerView.delegate = self

    textField.delegate = self
    textField.inputView = pickerView
}

And the extensions

// MARK: - UIPickerViewDelegate

extension ViewController: UITextFieldDelegate {

    func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
        pickerView.isHidden = false
        return false
    }
}

// MARK: - UIPickerViewDelegate

extension ViewController: UIPickerViewDelegate, UIPickerViewDataSource {

    func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 1
    }

    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        return myItems.count
    }

    func pickerView( _ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        return myItems[row].name
    }

    func pickerView( _ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        textField.text = myItems[row].name
        pickerView.isHidden = true
    }
}
