I would like to add, that whatever we do, that we are able to support Android devices as well. I know this is a swift forum and maybe it's just a 'given' or an 'of course' but for a strong server side swift notification service to exist and thrive, I would think there needs to be that kind of support. Maybe there aren't any technical blockers to that - in this proposal but just wanted to mention it. Right now I am using Urban Airship and implemented, what they expect, inside my Vapor app and it works well with both iOS and Android devices.
thoughts?
