            // sure that it's the same as the target (presumably a test) we're building right now.
            //
            // Using that knowledge, we can do build setting tricks to defer choosing the bundle
            // loader path until Xcode build time, when the platform is known. There's no build
            // setting that conclusively says whether the current platform uses deep bundles:
            // that would be too easy. But in the cases we care about (unit test bundles), the
            // current bundle will have a style matching the style of the bundle loader app, so
            // we can take advantage of that to do the determination.
            //
            // 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.
