Ever since I've updated to Xcode 8.2 (GM seed, from the App Store), I have been stuck at the following error:

Use Legacy Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.

So I went to my target's Build Settings, and searched for SWIFT_VERSION to see where I was erring. However, I was surprised to find that it was already set to No!

How do I fix this?
