Swift3 optionals chaining in IF conditions bug?

by

It’s not a bug. It is, alas, intentional. Implicit unwrapping of optionals in comparisons (>) has been removed from the language.

So, the problem now is that what’s on the left side of the > is an Optional, and you can no longer compare that directly to 4. You have to unwrap it and get an Int, one way or another.
