Module bundle not found when using dynamic library

Description

The generated resource bundle accessor Bundle.module crashes in a test target because it cannot find the bundle of a dynamically linked library.

The setup is the following:

BaseLibrary package defines a dynamic library that contains a resource file
ClientLibrary package defines another library that depends on BaseLibrary
ClientLibrary has a test that tries to access the resource in BaseLibrary

The sample code can be found here: https://github.com/erudel/spm-dynamic-bundles/

I've searched for similar issues and found this post and other similar reports, however these all seem to be using static libraries. I tried switching BaseLibrary to be a static library and everything works as expected, so it seems the issue only arises when using a dynamic library.

Expected behavior

The test target ClientLibraryTests passes

Actual behavior

ClientLibraryTests crashes with the following error:

BaseLibrary/resource_bundle_accessor.swift:40: Fatal error: unable to find bundle named BaseLibrary_ BaseLibrary

Steps to reproduce

Clone project https://github.com/erudel/spm-dynamic-bundles/
Double click on ClientLibrary/Package.swift to open the project with Xcode
Select Product > Test (cmd-U)

EDIT: after finding https://github.com/apple/swift-package-manager/pull/3824 it seems that, if this is indeed a bug, the problem lies in the accessor generated by Xcode and not by SPM. Is anyone able to confirm this?
