- Alice calls Bob on Signal and they start talking
- Charlie calls Alice on Not-Signal.
- Alice chooses to "Hold & Accept" putting Bob on Hold while the call with
Charlie connects.
- If Alice ends the call with Charlie, we're back in Signal-iOS and
talking to Bob, no problem.
- However, if, before ending the call with Charlie, Alice tries to swap
*back* to bob, bob won't hear any audio in the callkit screen. Alice
has to switch back to the Signal screen before the audio is transmitted.
// FREEBIE
...in response to CR, move the AudioService off of the CallViewController
Adopt multiple observer pattern vs. a singular delegate. Doing so
required implementing some machinery to address the ARC (see:
Weak.swift)
// FREEBIE
In the process, extracted the CallDelegate to allow the
CAllViewController to observe useful call state properties (call.state
and call.isMuted)
// FREEBIE
* Ensure NotificationsManager has dependencies
Otherwise it's easy to mess up the order of the required dependencies.
* move AccountManager into Environment, it's heavy to construct
