Signal for iOS

Signal allows you to make private phone calls and we are working on bringing secure messaging to it soon.

Building

1. Clone the repo to a working directory

2. CocoaPods is used to manage dependencies. 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 update
pod install

occasionally, CocoaPods itself will need to be updated. Do this with

sudo gem update

3. Open the Signal.xcworkspace in Xcode. Build and Run and you are ready to go!

Translation

Help us translate Signal! The translation effort happens on Transifex

Interoperability

Signal works with RedPhone on Android.
