Recently I found out that I can get rid of tons of boilerplate code by creating my own Xcode file templates, but then I thought, that it would be cooler to create group with all files stored inside this group. However, I didn't find any solution. Only one answer that was close to my question was Creating sub-groups in XCode 4 Templates, but I tried it and doesn't work
