Xcode 15.0.1 GM - Redefinition of module SwiftBridging

We just built our app with Xcode 15.0.1 GM and we are getting the following error: Redefinition of module 'SwiftBridging'. We have mode no changes and the app builds fine with Xcode 15.0. Is anyone else experiencing this issue?

Upon further investigation we found that the build process was referencing two different module.modulemap files for the SwiftBridging module:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/swift/module.modulemap

/Applications/Xcode_15.0.1.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/swift/module.modulemap

After renaming Xcode_15.0.1.app to Xcode.app the app is able to build successfully. We also have success when having no Xcode.app file in Applications with this structure:

Xcode_14.3.1.app
Xcode_15.0.0.app
Xcode_15.0.1.app
Xcode-beta.app
10

Had the same issue here with Xcode 16.1 (Current AppStore Xcode.app) and Xcode16.0 manually downloaded. Renaming the Xcode.app in the /Applications to something else than Xcode.app solved the problem.
