make delegate methods optional

[tereks]

Hi, can I suggest to make all delegate's methods optional so if I need only one method I don't need to add another empty method

Good idea, we'll look into it. You're also welcome to make a pull request.

Sorry, closed this by accident. Reopened now. Not sure if marking the methods optional is possible though, as this would require them to be marked @objc which is not possible as their parameter is a struct.

I think we could make it work by adding a protocol extension which implements both methods and does nothing. It's a hack, but it could probably work.

I think creating protocol extension is best choice.
