In swift APNumberpad delegate method is not calling

[nagurbee]

• (void)numberPad:(APNumberPad *)numberPad functionButtonAction:(UIButton *)functionButton textInput:(UIResponder *)textInput {

}

this method is not calling in swift

private func numberPad(_ numberPad: APNumberPad, functionButtonAction functionButton: UIButton, textInput: UIResponder & UITextInput) {
print(textInput)

    textInput.insertText("#")

}

am using above code in swift..

Most likely, initialization needs to be corrected.
This basic example works for me when adding APNumberPad via SwiftPM:

import UIKit
import APNumberPad

class ViewController: UIViewController {
    @IBOutlet weak var textField: UITextField!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let numberPad = APNumberPad(delegate: self)
        numberPad.leftFunctionButton.setTitle("#", for: .normal)
        textField.inputView = numberPad
    }
}

extension ViewController: APNumberPadDelegate {
    func numberPad(
        _ numberPad: APNumberPad,
        functionButtonAction functionButton: UIButton,
        textInput: UIResponder & UIKeyInput
    ) {
        textInput.insertText("#")
    }
}
