With Xcode9 I was able to import a framework the following way:
`@testable import MyFramework`
and this would allow me to invoke internal functions and avoid having to mark everything used as Public. This no longer works in Xcode10. I get errors of the type `error: Couldn't lookup symbols:` (importing without the @testable does work but would require marking everything used as Public).
Has anyone found a fix for making @testable work in Xcode10 playgrounds?
