iOS - send email from pre set address (NOT from users address) to set address in background? Ok for app store? -

so seems question ios - send email automatically (not user's account) tackles in objective-c can't find answer swift.

i creating app app store ideally needs compliant apple's privacy restrictions (i know have issues sending emails/texts in background)-

i need have email set message body (as in nothing editable user, pre programmed) sent 1 of email addresses (not accessing user's @ all) of email addresses (again, pre set).

ideally don't want user see email form or know email being sent - when button clicked, button 1 thing , want email function called along it. know apple doesn't allow email transparent user if being sent email address 1 of email addresses can't see why i'd violating anything.

i have looked can't figure out how in background (not pulling mail form, etc).

in swift, how can send set email 1 of email addresses of email addresses in background?
