Ok, so in my case it was not so sensitive, I had generated a publish profile for one of my projects, that said I don’t want the world and their aunty to be able to publish their apps to my server so I needed to remove my sensitive data from git.
git filter-branch --index-filter 'git rm --cached --ignore-unmatch mySensitive.data'
--prune-empty --tag-name-filter cat -- --all
git commit -m "Add Rakefile to .gitignore"
git push origin master –force
The above removes the file from history, you could add it to your .gitignore to ensure it’s not accidently added again.
