This should be WTFMove(pathString) to avoid some reference count churn.

This should be WTFMove(root) to avoid some reference count churn.

The "inline" here is not needed, has no effect.

I think this is better as a one liner without a local.

    return adoptCF(CFBundleCopyBundleURL(m_bundle.get())).get();

Also, there is no need to explicitly specify the URL constructor. It’s not an
explicit constructor.

I think the "Ref" in the name of this local variable is misleading. We normally
wouldn’t use that name for something of in a RetainPtr. Why not just call this

This is incorrect, and will interpret the path as Latin-1 instead of UTF-8,
incorrectly handling any path with any non-ASCII characters.

Since we are returning a WTF::String and not a C string containing a file
system representation, we must use CFURLCopyFileSystemPath, not

return adoptCF(CFBundleCopyResourceURL(m_bundle.get(),
name.createCFString().get(), type.createCFString().get(),
