With tools like spacecommander (https://github.com/square/spacecommander <https://github.com/square/spacecommander>) and clang-format for XCode (https://github.com/travisjeffery/ClangFormat-Xcode <https://github.com/travisjeffery/ClangFormat-Xcode>), it can enforce the rules and auto run the formatter constantly so nicely formatted code stays that way. It saves alot of time, and keeps acleaner commit log without constant formatting adjustment.

This would be a fantastic thing to have, but of course someone has to build it ;)
