3. Declaring and initializing a IBOutlet UIDropDownTextField so an UITextField can hook from interface

      // Mark - Initializing drop down items in UIDropDownTextField datasource
      
      func dropDownTextField(_ dropDownTextField: UIDropDownTextField, setOfItemsInDropDownMenu items: [UIDropDownObject]) -> [UIDropDownObject] 
      {
                return socialMediaList
