If you really like this guide and adopt it as it is, great. If there are parts that you do not agree with and you change them within your guide, that is great as well. The appropriate style for you and your team is the one that you and your team feel comfortable with, and it may or may not be different from the guide in this book. We should also point out that Swift is a very young language and people are still trying to figure out the appropriate style to use with Swift; therefore, what is recommended today may be frowned upon tomorrow. Don't be afraid to adjust your style guide as needed.
