Thank you for help.

EDIT
I have found a solution on the net, though I don’t understand meaning.
open /Applications/Utilities/XQuartz.app
ssh -Y <user-name>@<host>
export DISPLAY=:0.0
EDIT.
The above “solution” was my illusion. It did not work.
EDIT.
On Emacs.app, This is OK.
M-x shell
swipl
?- emacs.
On terminal. This is not OK.
emacs
M-x shell
swipl
?- emacs.
(The same error message)
EDIT.
This works ! Put the one line just before the swipl command.
% export DISPLAY=:0.0
% swipl
?- emacs.
