I updated my answer to use an implicit optional instead of an explicit one.

This will crash when parentView becomes nil finally. You can leave it as it was before, or unwrap the optional inside the while loop

It doesn't crash on the IBM Swift Sandbox 3.0-dev. The code I tested is here.

not nice :/ we declare variable outside of the loop, make iteration in the end of code block, and at all have too many lines of code
