User Profile

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?

Hey!I was wondering if there is a way to implement the following scenario: a system of complementary applications that supports SSO in the following way - logging into a "manager" application would automatically log the user into the rest of the applications system (ease of access is critical).Question 1: Is such a SSO scenario possible if the applications have a different developer team?Question 2: Is it possible for the "manager" app to be the single one to send notifications, when being notified by the other applications when a certain event occurs (message received, etc.)?Question 3: Is 100% reliability achievable provided both push notifications and web sockets are used?I would highly appreciate answers to and ideas regarding any of these questions, but I am especially interested in the answer to Q1.Thank you!
