It seems to be a bug in Swift. See discussion on Apple developers portal

It is said to be fixed in Xcode version that is about to be released. But for now there is temporary workaround:

Go to your target Build Settings and set Reflection Metadata Level flag to None

  • If you're using Cocoapods, refer to this stackoverflow.com/a/47114775/5854394
  • Thank you very much! This is so obvious, I created a Podfile and mistakenly opened the file with the type .xcodeproj instead of .xcworkspace.
  • Great answer. I added a new Target to my XCode project. I did not select "Target Membership" for the old files but XCode auto added ( a file I didn't want ) to the Compile Sources list. That caused my duplicate Symbol. Removed. Worked. Boom!.
