Xcode 9 code snippets bug

Question

I have a list of code snippets that works perfectly in Xcode 8.3.3, but in Xcode 9 I don't see them when I start typing. I tried to change Completion Scopes and I've got a new bug: when I press tab my snippet completes incorrectly as seen in the screenshot below.

Here is the repository with source of snippets.

Let me know how to fix this bug please.

I also had many comment-scope snippets starting with //, and I support your question.

I don't know how to make them work, but I can propose a temporary solution. Set Completion Scopes to All and remove // from the prefix. Then add // to the snippet body:

    MARK: - Private helpers => // MARK: - Private helpers
