This is a fixed edition for ACCodeSnippetRepositoryPlugin for support Xcode 7.2 and above.
1. Fix MenuItems (I move the menuItems to 'Source Control' menu from 'Plugins' to avoid plugin conflicts);
2. Fix Snippets Path (Because Xcode 7.2 no longer recognize snippets in subfolders,
and I change the path to ../CodeSnippets/ ).
3.Follows the acoomans's guide, and noticing my fix issues above.
