WIP: WebRTC calling
* 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

Apart from the general `BUILDING.md` there are certain things that have
|
||||
to be done by Signal-iOS maintainers.
|
||||
|
||||
For transperancy and bus factor, they are outlined here.
|
||||
|
||||
## Dependencies
|
||||
|
||||
Keeping cocoapods based dependencies is easy enough.
|
||||
|
||||
`pod update`
|
||||
|
||||
### WebRTC
|
||||
|
||||
We don't currently have an automated build (cocoapod/carthage) setup for
|
||||
the WebRTC.framework. Instead, read the WebRTC upstream source and build
|
||||
setup instructions here:
|
||||
|
||||
https://webrtc.org/native-code/ios/
|
||||
|
||||
Once you have your build environment set up and the WebRTC source downloaded:
|
||||
|
||||
cd webrtc
|
||||
# build a fat framework
|
||||
src/webrtc/build/ios/build_ios_libs.sh
|
||||
# Put it in our frameworks search path
|
||||
mv src/webrtc/ios_libs_out/WebRTC.framework ../Signal-iOS/Carthage/Builds
|
||||
|
||||
