Delegate is nil.

[cukingpro]

`class DecimalNumberPad: APNumberPad {

convenience init() {
    self.init(delegate: DecimalNumberPadDelegate())
    leftFunctionButton.setTitle(".", for: .normal)
}

}`

`class DecimalNumberPadDelegate: NSObject, APNumberPadDelegate {

func numberPad(_ numberPad: APNumberPad, functionButtonAction functionButton: UIButton, textInput: UIResponder & UITextInput) {
    textInput.insertText(".")
}

}`

When I create delegate class, the delegate is nil when I click on left button.

It doesn't happen when I set delegate is viewcontroller

It happens because delegate is stored as weak:

You need to keep a strong reference to your DecimalNumberPadDelegate somewhere.
