Answer 1

you could do something like the following:

class ViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {

  var colors = ["red","green","blue"]

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

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

  func pickerView(pickerView: UIPickerView, attributedTitleForRow row: Int, forComponent component: Int) -> NSAttributedString? {
    let color = (row == pickerView.selectedRowInComponent(component)) ? UIColor.orangeColor() : UIColor.blackColor()
    return NSAttributedString(string: colors[row], attributes: [NSForegroundColorAttributeName: color])
  }

  func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
    pickerView.reloadAllComponents()
  }
}
