Omit default parameters in README examples

No description provided.

I think it's best to leave those there so that new developers know they can use those parameters.

[BasThomas]

Wouldn't it be better to in that case show what the completionHandler does?
Something like completion: { /* do something after the view has been dismissed */ })

[julianschiavo]

Yeah, I think that would be a good idea

[AvdLee]

In contrast to previous comments, I do agree we can remove the completion blocks here. They are part of the default Swift API and don't need any explanation from us.

Starting here explaining how default APIs work and with consistency in mind would require us to describe a lot more default APIs.

Therefore, we should assume implementors to be able to explore these APIs themselves.
