Wrong Module-Swift.h header is generated with import to itself

问题

So I am mixing swift and objc everywhere. I have development pod called Renetik. It has some extensions written in swift but it's mostly objective c code. Now, I wrote some class and used it in main project fine and wanted to move it to Renetik development pod. When I do it somehow in Renetik-Swift.h wrong import is generated and project won't compile.

#import <Renetik/Renetik.h>

Then I experimented a lot. And found out that wrong import is generated when I actually return from swift class function type defined in pod itself. It is happening just when I try to make it in Development Pod where is mostly objective-c. Other swift extension and classes works juts when I try to modify some class to return objc class defined in pod itself.

I will write example when everything is OK. This compiles fine and I can call function testMe from main project:

@objc public class ReplaceMe: NSObject {
    @objc public func testMe() {
        let variable = CSResponse<NSObject>()
        variable.cancel()
    }
}

Just this small change and wrong header is generated as I stated before:

@objc public class ReplaceMe: NSObject {
    @objc public func testMe() -> CSResponse<NSObject> {
        let variable = CSResponse<NSObject>()
        variable.cancel()
        return variable
    }
}

I use use_frameworks! in podfile as use_modular_headers! don't work for other reasons. I m able to setup branch in Github project where this happens as this is open source.

So it seems only not hack possibility is to create other pod just for Swift files. Define in podspec dependency to released verison, and in host application podfile add dependencies with :path => .
