Keyboard does not come up when I tap on textfield

[tesddev]

Even after I set isSearchEnable to true, keyboard fails to come up. See code snippet below.

let senderStateTextField: TesDropDownTextField = {
        let textField = TesDropDownTextField()
        textField.isSearchEnable = true
        textField.placeholder = "Origin"
        return textField
    }()

I then later set the textfield to become firstresponder in the listWillAppear delegate method

senderStateTextField.listWillAppear {
        self.senderStateTextField.becomeFirstResponder()
 }

This brought up the keyboard but brought along several bugs with it.

1. When I start typing, it creates another list up.
2. When I select, it dismisses only the first list and leaves the original one
3. When I click on any of the list in the original list that fails to dismiss, I get an "index out of range error"
4. Tapping outside doesn't also dismiss the original list.

If anyone has a correct way of using the search feature, please help me.
