I suggest using early return here instead of nesting everything inside an if statement.

I don’t think we need a RetainPtr for the return value from a method that is just passed on to another function and then dropped. I suggest either using the type "id" here instead, or not using a local variable at all.

Also, why is the message body called wkMessageBody instead of just body or messageBody?

Can we come up with some type checked cast for use in cases like this rather than using a straight C cast?

Typo here: "inected".

Use of RetainPtr is OK here if the return type of rootObject is a RetainPtr. But if not, then I suggest just using "id" rather than "RetainPtr<id>".
