It is a hidden option, and one that took me a LONG time to figure (but i'm slow like that). Go to Setting > Mail, Contacts, Calendars > Gmail > then toggle Archive Messages to off. That replaces the Archive button with the trash can that used to be there and allows you to swipe to delete. HTH.
edit: nevermind. i skipped over the whole "new gmail app" part...that was in the title. all this is for the native mail app. my bad.
