I don't know much about ios. But in macos there are ways to access imessage chat logs or send imessages programmatically. You can create an applescript and do all sorts of stuff. So while I do get that giving this sort of access to an app on your iphone should at least be done through explicit intentful consent from the user, I do not see the impossibility in it. And the fact that there is all this crapp around should not make it impossible for us to have good things, either.
