I am using Vim 9.1

After installing Vim, swap files are created normally.

But if I create a $MYVIMRC file, Vim stops creating swap files.

If I put the line ‘set swapfile’ in the $MYVIMRC file, Vim still won’t create swap files.

If I open a file and enter the command ‘:set swapfile’, edit the file and close it, Vim still won’t create swap files.

If I remove the $MYVIMRC file, vim creates swap files normally.

I was expecting Vim to keep creating swap files, even after I create the $MYVIMRC file.
