Hi,
Our application consists of several modules & the application. None of these modules nor the application has WebKit as a dependency.
One module does have a dependency to a closed-source Swift-framework that, on itself, has a dependency to WebKit (based on the swiftinterface).
The dependency itself has been build with Swift 5.5 with BUILD_LIBRARY_FOR_DISTRIBUTION-flag enabled.
We import this module using @_implementationOnly import Foo & our module also has the BUILD_LIBRARY_FOR_DISTRIBUTION-flag enabled.
If we clean the build-folder in Xcode, then build the application, our app does compile.
However, the next time we make a (incremental) build after that, it results in a WebKit build error Could not build Objective-C module 'WebKit'.
The following log is outputted:
<module-includes>:1:9: note: in file included from <module-includes>:1:
#import "Headers/WebKit.h"

We never have encountered this problem before & it works fine when compiling with Xcode 14.3.1. I've been trying to tackle this issue since the 15.0 RC release and I cannot find a solution for this. Does anyone know how to fix this issue?
