Issue Description:

Swift 5.3 introduces support for binary targets but it seems like that does not include support for Objective-C based XCFrameworks.

I created a sample project (see attachments) that contains a swift package with 1 library that contains 4 targets and modules of the same name:

• A Swift source target

• A Swift binary target

• An Objective-C source target

• An Objective-C binary target

Plus an app to see if they can be used.

The app and the package are within the same workspace, the app has:

• a dependency on the libraries that are created by the package

• has a source file that imports the 4 modules from above and

• within the same source file tries to call code from the module.

Expectation:

**The code builds successfully.

Actual:

While the import statements work, I can not create instances of classes that are declared within the Objective-C binary.

Module 'BinarySampleHelloWorldObjC' has no member named 'EchoObjC'

The folder Package contains a script for regenerating the XCFrameworks after applying changes.
