Swift 3 upgrade gives FIXME: "comparison operators with optionals were removed from the Swift Standard Library..."

Hi,

I got this FIXME at the top of my code when I updated to Swift 3.

// FIXME: comparison operators with optionals were removed from the Swift Standard Libary. // Consider refactoring the code to use the non-optional operators. fileprivate func < <T : Comparable>(lhs: T?, rhs: T?) -> Bool { switch (lhs, rhs) { case let (l?, r?): return l < r case (nil, _?): return true default: return false } }

I have NO CLUE WHAT THIS MEANS!! Can someone please help / explain what's going on?

I am using a Date comparison in the code. I.e. if it's been longer than 30 minutes, send this notification, otherwise reset the timer.

I use Date.timeIntervalSinceReferenceDate; if thisTime > lastTime + waitTime, call func.

Thanks!!
