Why ios/build is not included to gitignore by default?

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        ios/build/

CodePudding user response：

As mentioned in gitignore:

If there is a separator at the beginning or middle (or both) of the pattern, then the pattern is relative to the directory level of the particular .gitignore file itself.

Otherwise the pattern may also match at any level below the .gitignore level.

Once you have changed the pattern to build/, don't forget you also have, to validate if that works:

git check-ignore -v -- ios/build/aFile

That should print the .gitignore rule line, which does ignore the folder.
