How to stop pushing your swap files

I'm an avid vim user. I'm not ashamed to admit it. But I don't really need everyone to know. If you are a vim and tmux user, you know that sometimes you push your changes while a vim process is still open and this ends up pushing your swap file to you remote git branch.
