Swift3 optionals chaining in IF conditions bug?

Question

This code worked just fine in Swift 2.3 and I don\'t understand why I have to unwrap TestClass to check if number is bigger than 4. This is whole point of chain

Answer 1

First of all, where are you initialising your test var? Of course it'll be nil if you don't give it a value!

And regarding optional chaining, what's the issue writing :

if let optionalInt = test?.optionalInt, optionalInt > 4
{

}

As always, safety > brevity.
