We have internal tooling that publishes Swift interfaces for comment and review. For Swift-only frameworks our tooling works fine simply getting the abstract syntax tree of the Swift source code. However, this approach doesn't work when the source contains, or is primarily, Objective-C.

We have an alternate process that will process *.swiftinterface files, but we have yet to find a process that works for generating these files from Objective-C or mixed source except for using the internal Xcode Generated interface. We are searching for a programmatic solution.

Based on comments here (jpsim/SourceKitten#405) I was hoping that this tool might solve our issue. However, when I run it on a simple dummy framework, which contains a SwiftClass object and an ObjCClass object, the generated interface only includes the SwiftClass interface even though the bridged ObjCClass is exposed.

Is ModuleInterface intended to work with mixed source, or is it strictly for Swift-only frameworks (or the Swift-only portion of mixed frameworks)?
