Siri to Swipes
For this to be able to work, you will need a swipes-supported email client (I personally use mailbox). Configure your email client so that it will automatically move emails that are from your email to the designated 'add to swipes' folder. Once this is done, you should be able to see it in swipes once you made a reminder using Siri. The subject of the email will be the title of the task and the body as it's notes (limited to a few lines).
