            // Unfortunately, the build setting for the bundle structure (CONTENTS_FOLDER_PATH)
            // includes the WRAPPER_NAME, so we can't just interpolate that in. Instead, we have
            // to use another trick with build setting operations and evaluation. By using the
            // $(:file) operation, we can extract the last component of the contents path: either
            // "Contents" or the current bundle name. Then, we can interpolate with that expected
            // result in the build setting name to conditionally choose a different loader path.

            // The conditional that decides which path is used. This is a complex Xcode build setting
            // expression that expands to one of two values, depending on the last path component of
            // the CONTENTS_FOLDER_PATH variable. As described above, this will be either "Contents"
            // for deep bundles or the bundle file name itself for flat bundles. Finally, to santiize
            // the potentially invalid build setting names from the bundle file name, it converts that
            // to an identifier. We rely on BUNDLE_LOADER_BUNDLE_STYLE_CONDITIONAL_<bundle file name>
            // being undefined (and thus expanding to nothing) for the path resolution to work.
