How to hide keyboard while using UIPickerView with Swift 4?

I have got a problem with my code because I am using a UIPickerView but when we switch from one textfield to another, keyboard is not hiding despite my code below.

I would be glad to have someone to help me.

(I have done research about this error but none of code I have seen solved my problem)

@IBOutlet weak var colorPickerView: UIPickerView!



public func numberOfComponents(in pickerView: UIPickerView) -> Int{

    return 1

}



public func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{

    return list.count

}





func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {

    self.view.endEditing(true)

    return list[row]

}



func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {

    self.colorTxtField.text! = self.list[row]

    self.colorPickerView.isHidden = true

}





func textFieldDidBeginEditing(_ textField: UITextField) {

    if textField == self.colorTxtField {

        self.colorPickerView.isHidden = false

        textField.endEditing(true)



    }

}

I would be glad to have someone to help me.

Maybe calling endEditing inside of textFieldDidBeginEditing is not supported / allowed. Have you tried using textFieldShouldBeginEditing instead and return false for self.colorTxtField.

I think you are showing pickerView wrongly. You, need not to write

func textFieldDidBeginEditing(_ textField: UITextField)

instead to show picker, just write this line in your viewDidLoad

self.colorTxtField.inputView = self.colorPickerView

thank for your response , now I have got this error *** Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller:<UICompatibilityInputViewController: 0x7ff65b720ef0> should have parent view controller:<project1.Add2ViewController: 0x7ff65b5292b0> but requested parent is:<UIInputWindowController: 0x7ff65c04e800>'

seems like your view hierarchy is not correct. Can you tell me how you are placing this textField and pickerView in your viewController ?
