UIView textFieldShouldReturn not working - ios

Question

I am having some problems with function textFieldShouldReturn as far at i understand it should be called when enter are pressed on the keyboard but it does not. I have tried to search for solution on google and here but have not found a answer that solved the problem because most of the answers here on the webpage i have fund are a 3 years or older and the solutions from those did not help much.
I am using it in a UIView where the delegates for the textField is set in the function awakeFromNib() and i have tried some other delegate function textViewDidChangeSelection that does work so i am at a lost why it is not working.
Here is how the xib file looks
Here is the code that i am using as a popup:
import UIKit
class CuePointPopup: UIView,UITextFieldDelegate,UITextViewDelegate
{
#IBOutlet var labelCueNumberInImage: UILabel!
#IBOutlet var labelCueNumber: UILabel!
#IBOutlet var labelLayerName: UILabel!
#IBOutlet var labelPageNumber: UILabel!
#IBOutlet weak var view: UIImageView!
#IBOutlet var textFieldWhoText: UITextField!
#IBOutlet var textViewWhatText: UITextView!
#IBOutlet var textFieldWhereText: UITextField!
#IBOutlet var textFieldPageNumber: UITextField!
#IBOutlet var textFieldCueText: UITextField!
#IBOutlet var boxArrowLeft: UIImageView!
#IBOutlet var boxArrowRight: UIImageView!
#IBOutlet var boxArrowLeftTopConstraint: NSLayoutConstraint!
#IBOutlet var boxArrowRightTopConstraint: NSLayoutConstraint!
var cuePointObj:CuePoint!
var blockBtnClickedSave:((CuePoint) -> ())!
var blockBtnClickedCancel:((CuePoint) -> ())!
var blockBtnClickedDelete:((CuePoint) -> ())!
var blockTextChangedForPageNumber:((String, CuePoint) -> ())!
#IBOutlet var btnOutletVisibleOnPage: UIButton!
var isVisible = false
class func loadNib() -> CuePointPopup
{
return Bundle.main.loadNibNamed("CuePointPopup", owner: self,options: nil)!.last as! CuePointPopup
}
override func awakeFromNib() {
self.textFieldWhoText.delegate = self
self.textViewWhatText.delegate = self
self.textFieldWhereText.delegate = self
self.textFieldCueText.delegate = self
textViewWhatText.text = "Hello"
}
func setViewData(cueModel:CuePoint) {
self.cuePointObj = cueModel
labelCueNumberInImage.text = cueModel.cueNumber
labelCueNumber.text = "Cue #:" + cueModel.cueNumber
labelLayerName.text = "Layer #:" + cueModel.layerName
labelPageNumber.text = "Page #:" + cueModel.pageNumber
textFieldPageNumber.text = cueModel.pageNumber
textFieldWhoText.text = cueModel.whoString
textViewWhatText.text = cueModel.whatString
textFieldWhereText.text = cueModel.whereString
textFieldCueText.text = cueModel.cueTextString
if cueModel.isVisibleOnPage == true {
btnOutletVisibleOnPage.setImage(UIImage(named: "SelectedBox"), for: [])
btnOutletVisibleOnPage.tag = 1
}else{
btnOutletVisibleOnPage.setImage(UIImage(named: "UnselectedBox"), for: [])
btnOutletVisibleOnPage.tag = 0
}
}
func textFieldDidEndEditing(_ textField: UITextField) {
if textField.text != "" {
if blockTextChangedForPageNumber != nil {
self.blockTextChangedForPageNumber(textField.text!, self.cuePointObj)
}
}
}
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
//self.view.endEditing(true)
if self.textFieldWhoText.isEditing {
self.textFieldWhoText.endEditing(true)
} else if self.textFieldCueText.isEditing{
self.textFieldCueText.endEditing(true)
} else if self.textFieldWhereText.isEditing {
self.textFieldWhereText.endEditing(true)
} else {
self.textViewWhatText.endEditing(true)
}
//self.view.endEditing(true)
return false
}
}
Here is how i load the XIB
#IBOutlet weak var bookView: UIView!
var objCuePopup:CuePointPopup!
if objCuePopup != nil {
objCuePopup.removeFromSuperview()
}
objCuePopup = CuePointPopup.loadNib()
objCuePopup = CuePointPopup.loadNib()
objCuePopup.frame = CGRect(x:cuePointModal.cueX, y:0, width:465, height:410)
objCuePopup.center = CGPoint(x:objCuePopup.center.x, y:cuePointModal.cueY + 5)
//Set Y value for Popup View
if objCuePopup.frame.origin.y < bookView.frame.origin.y {
objCuePopup.frame.origin.y = bookView.frame.origin.y
}
let popupMaxY = objCuePopup.frame.maxY
let bookViewMaxY = bookView.frame.maxY
if popupMaxY > bookViewMaxY {
objCuePopup.frame.origin.y = bookViewMaxY - objCuePopup.frame.size.height
}
//Set X value for Popup View
if cuePointModal.cueX > 455 {
objCuePopup.frame.origin.x = cuePointModal.cueX - 455
objCuePopup.boxArrowLeft.isHidden = true
objCuePopup.boxArrowRight.isHidden = false
let rightY = cuePointModal.cueY - objCuePopup.frame.origin.y
objCuePopup.boxArrowRightTopConstraint.constant = rightY + 3
}else{
objCuePopup.frame.origin.x = cuePointModal.cueX + 40
objCuePopup.boxArrowLeft.isHidden = false
objCuePopup.boxArrowRight.isHidden = true
let leftY = cuePointModal.cueY - objCuePopup.frame.origin.y
objCuePopup.boxArrowLeftTopConstraint.constant = leftY + 3
}
objCuePopup.setViewData(cueModel: cuePointModal)
objCuePopup.textFieldWhoText.delegate = self
objCuePopup.textFieldWhereText.delegate = self
objCuePopup.textViewWhatText.delegate = self
objCuePopup.textFieldCueText.delegate = self
bookView.addSubview(objCuePopup)
I hope that someone here can help me with this problem.
