I set up source control on a small project with Xcode, but I quickly found that there are a lot of random files and folders that Xcode makes for my project that are also getting picked up by git. Not sure if it is helpful to keep them to perfectly restore a previous commit, but it definitely makes it harder to view changed files when the list of changes after changing one file comes out to a length of 168. Is there any way that I can add all of these automatically to gitignore or at least hide them?
