This output is expected, everything went well and the extension should be available in the admin panel.

The swiftmailer/swiftmailer warning is caused by Flarum itself and will be present in all Composer outputs for all extensions. It has to be fixed in the upstream Laravel package first, then Flarum will be able to use that new version and get rid of the message. It might take a few more Flarum releases until it disappears.

If there's any issue with the extension itself let us know and we'll take a look!
