Couldn't lookup symbols in playground

I was trying to run the example in the Readme in a playground in project that has the package as a dependency, but I'm getting the following errors:

error: Couldn't lookup symbols:
  static __C.CvType.CV_8UC1.getter : Swift.Int32

  static __C.CvType.CV_8UC1.getter : Swift.Int32

Any idea why this might be? It's a brand new completely empty project.

I have just created a new Xcode project using the code provided in the Readme. Feel free to run it and compare its configuration with yours to identify any differences.
