Dependency Details
We have a couple of dependency management tools. We us Carthage for managing frameworks, but because some of our dependencies are not yet framework compatible, we use Cocoapods to manage the remainder in a static library.
2.1) CocoaPods is used to manage the dependencies in our static library. Pods are setup easily and are distributed via a ruby gem. Follow the simple instructions on the website to setup. After setup, run the following command from the toplevel directory of Signal-iOS to download the dependencies for Signal-iOS:
pod install
If you are having build issues, first make sure your pods are up to date
pod repo update
pod install
occasionally, CocoaPods itself will need to be updated. Do this with
gem update cocoapods
pod repo update
pod install
2.2) Framework dependencies are built and managed using Carthage. Our prebuilt WebRTC.framework also resides in the Carthage/Build directory.
If you don't have carthage, here are the install instructions.
Once Carthage is installed, run:
// DO NOT run: `carthage update` or `carthage checkout`.
git submodule update --init
carthage build --platform iOS
3. XCode
Open the Signal.xcworkspace in Xcode.
open Signal.xcworkspace
In the Signal target on the General tab, change the Team drop down to your own. On the Capabilities tab turn off Push Notifications and Data Protection. Only Background Modes should remain on.
Some of our build scripts, like running tests, expect your Derived
Data directory to be $(PROJECT_DIR)/build. In Xcode, go to Preferences-> Locations,
and set the "Derived Data" dropdown to "Relative" and the text field
value to "build".
Build and Run and you are ready to go!
Known issues
Features related to push notifications are known to be not working for third-party contributors since Apple's Push Notification service pushs will only work with Open Whisper Systems production code signing certificate.
If you have any other issues, please ask on the community forum.
Building WebRTC
A prebuilt version of WebRTC.framework resides in our Carthage submodule (see above). However, if you'd like to build it from souce, this is how it's done.
These instructions are derived from the WebRTC documentation:
https://webrtc.org/native-code/ios/
# 1. Install depot tools
cd <somewhere>
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
cd depot_tools
export PATH=<somewhere>/depot_tools:"$PATH"
# 2. Fetch webrtc source
cd <somewhere else>
mkdir webrtc
cd webrtc
fetch --nohooks webrtc_ios
gclient sync
# 3. Build webrtc
cd src
tools-webrtc/ios/build_ios_libs.sh
# 4. Move the WebRTC.framework into Signal-iOS's Carthage directory
mv out_ios_libs/WebRTC.framework <Your Signal-iOS repository>/Carthage/Build/iOS/
