Xcode – Adding A UIGestureRecognizer To A custom .xib View

I want to add a tab recognizer to a custom .xib file view in my ios swift app. Here’s the code from the owner class of the .xib file:

import UIKit

class WordLabel: UILabel {
    
    
    @IBOutlet weak var wordLabel: UILabel!
    @IBOutlet var wordFrame: UIView!

    
    
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        commonInit()
        

//I added the tab recognizer here
        wordLabel.isUserInteractionEnabled = true
        let gestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(labelClicked(_:)))
        wordLabel.addGestureRecognizer(gestureRecognizer)

    }
        
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        commonInit()
    }
        
    func commonInit() {
        
        Bundle.main.loadNibNamed(K.wordLabelNibName, owner: self, options: nil)
        
        addSubview(wordFrame)
        wordFrame.frame = self.bounds
        wordFrame.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        

    }
    
    
    //should happen when label is tapped
    @objc func labelClicked(_ sender: Any) {
        print("UILabel clicked")
    }
    
  
}

When I ran the project on a phone simulator, there were no errors.

App Running On The Simulator

But when I clicked the labels that showed up, the message was not printed onto the console (meaning that the action was not triggered). What am I doing wrong?

Thank you for your help.
