Identify the version of Swift a project is using

I have a bunch of Xcode projects. When I open them in Xcode, is there any way to see which ones are using Swift 2.2 and which are using 3?

In the Build Settings section of a target, see the 'Use Legacy Swift Language Version' option. If that's set to 'Yes', you're using Swift 2.x; 'No' for Swift 3.
