问题
In Xcode I noticed that .DS_Store and *.xcuserstate always change and don't need to be commited. So, I wrote a .gitignore file that contains this:
.DS_Store
*.xcuserstate
among other entries. Then I used:
git rm --cached *xcuserstate
git rm ---cached .DS_Store
To remove the these file types already under version control. However, when I go to merge Xcode tells me that there are changes that need to be committed. Those changes include .DS_Store files and .xcuserstate files.
So, I tried this:How can I Remove .DS_Store files from a Git repository?
find . -name .DS_Store -print0 | xargs -0 git rm --ignore-unmatch
find . -name *.xcuserstate -print0 | xargs -0 git rm --ignore-unmatch
and I got the same result. How do I remove these files from source control for good?
回答1:
You need to commit your change after removing them from the staging area.
As you did already, run:
$ git rm --cached path/to/.DS_Store
$ git rm --cached *.xcuserstate
Note, you may have some in other directories, so you may need several invocations to get them all. At this point, your removals are staged in the index, but there's still more to do: add your .gitignore, and commit the final result:
$ git add .gitignore
$ git commit -m "Remove and ignore .xcuserstate and .DS_Store files."
Now they'll be removed from the repository, and ignored in the future. Note: this will remove the files for other people, even though you used git rm --cached locally. Unfortunately, there isn't much you can do about this. Also, the files are still in your history, so depending on what you do, you may see them in other branches until things get merged and all your branches are based on something that has the new commit.

Try git update-index --assume-unchanged *.xcuserstate .DS_Store and see if it helps
