First you need to set image(visible or hide) of button of eye for different state (selected or normal)

than connect IBAction and write code like

@IBAction func btnPasswordVisiblityClicked(_ sender: Any) {
        (sender as! UIButton).isSelected = !(sender as! UIButton).isSelected
        if (sender as! UIButton).isSelected {
            txtfPassword.isSecureTextEntry = false
        } else {
            txtfPassword.isSecureTextEntry = true
        }
    }
