Consider the following scenario. Two iOS apps are in the same app group, Alice and Bob. Alice is a Manager app, and Bob is a Chat app.
Alice is responsible for communication with the server, so even if (the user of) Bob receives a (text) message, the server would only notify Alice. Considering Bob is in the background state, how could Alice wake up Bob, so that Bob can update its content and schedule a local notification?
If Bob is suspended in the background, there is no good way for Alice to force it to resume.

Would you see a solution for this scenario, or would you change the architecture of the system altogether?
Would you see a solution for this scenario, or would you change the architecture of the system altogether?
The latter. In the iOS architecture, apps are expected to work as apps, that is, a program that’s primarily user facing [1]. Trying to bend that architecture to get an app to provide a system service is going to result in all sorts of headaches.
