There is no .gitignore inside a .git folder.
The is however a .git/info/exclude file, which allows you to exclude a file locally, generally when you want to exclude a file only for this specific repo (with an alias like this one):

git config alias.exclude "!sh -c 'echo \"$1\" >> .git/info/exclude' -"
git exclude UserInterfaceState.xcuserstate

If you need to exclude this file for all similar project, as Elnur Abdurrakhimov mentioned in his answer, exclude it globally.

echo UserInterfaceState.xcuserstate >> ~/.gitignore

But, as mentioned in "Do we need to check in *.xcuserstate?", if it is a type of file which should be ignored by any user of that repo, I would actually version a .gitignore at the top of the repo, with a content similar to:

*.xcuserstate 

That way, any user of that repo won't even realize that this file exists and is generated (whatever its name is): it won't show up in a git status ever.

Or you can ignore xcuserdata/ entirely (either in a global .gitignore, or in a versioned one, like the generic GitHub Objective-C.gitignore file.
