I created a Package which include Swift and C code, plus dependency to another swift package.
The package builds without problems with DEVELOPMENT-SNAPSHOT-2016-05-31-a.
But it doesn’t build with 3.0-PREVIEW-2.
I get the following error: fatal error: ClangModule ClangModule(SOLPOS) can't have SwiftModule(Strand) as a dependency.: …
When I move the C code in extra Package, it builds again.
But I would like to know if this behaviour is intended or a bug of spm.
You can find the project here:
