Answer 1

I can just add question, not answer.

if let has a local scope, so how could it be strong reference ?

Does guard let behave differently ?

I do not see how to declare if weak var

Thanks.

I'ts a lazy way of dealing with an optional but I've started using it all the time. Just wanted to make sure.
