using colors in uipickerview

Why would you avoid using NSAttributedString? I don't see why you would?

In any case, there's two ways to go about doing what you want to do:

Code:

    func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView
   {
        let view = UIView();
        let label = UILabel();
        label.textColor = UIColor.green;
        view.addSubview(label);
        //adjust frame rect's here to make sure it's actually visible
        return view
    }

^ This is really ugly in my opinion but it would work. You could also create a custom UIView xib interface file and that would be just fine.

If you're willing to break down and use NSAttributedString it is FAR easier and simpler. Here's an example:

Code:

    func pickerView(_ pickerView: UIPickerView, attributedTitleForRow row: Int, forComponent component: Int) -> NSAttributedString?
    {
        return NSAttributedString(string: "a pretty color", attributes: [NSFontAttributeName : UIFont(name: "Helvetica", size: 14)!, NSForegroundColorAttributeName : UIColor.red]);
    }
