Issue Description:

I have attached a project which builds successfully in Xcode 8 Swift 3, but fails to build in Xcode 9 beta 6 using the Swift 3 compatibility mode. It also fails to build in normal Swift 4 mode.

Xcode 9 gives me an error saying: "ViewController.swift:19:4: Ambiguous reference to member '+' " and lists "Found this candidate" exactly 40 times. Each candidate points to the same source location.

This has been an issue since either Xcode 9 beta 1 or 2.
