Strange. The following works for me in my .vimrc.

if v:version>=702
fun! NoSwapEncrypt()
if &key != ""
setlocal noswapfile
endif
endfun
au BufReadPost * call NoSwapEncrypt()
endif

Obviously, it has a different purpose, but nevertheless, it accurately
detects whether a file is encrypted or not, using BufReadPost.
