Redistributing ChatSecure Code on the App Store
Even though this project is open source, this does not mean you can reuse this code when distributing closed source commercial products. Please contact us to discuss licensing options before you start building your product.
If you are an open source project, please contact us to arrange for an App Store redistribution exception. For more information about why this is required, please read this blog post from Open Whisper Systems.
Cost for End Users
Downloading the ChatSecure app is 100% free because it is important that all people around the world have unrestricted access to privacy tools. However, developing and supporting this project is hard work and costs real money. Please help support the development of this project! We now also accept Bitcoin via Coinbase!

$ brew install carthage $ gem install cocoapods
Download the source code and don't forget to pull down all of the submodules as well.
$ git clone https://github.com/ChatSecure/ChatSecure-iOS.git $ cd ChatSecure-iOS/ $ git submodule update --init --recursive
Now you'll need to build the dependencies.
$ carthage bootstrap --platform ios # or carthage update --platform ios --cache-builds $ bash ./Submodules/CPAProxy/scripts/build-all.sh $ bash ./Submodules/OTRKit/scripts/build-all.sh $ pod repo update $ pod install
Next you'll need to create your own version of environment-specific data. Make a copy of
$ cp OTRResources/Secrets-template.plist OTRResources/Secrets.plist
You'll need to manually change the Team ID under Project -> Targets -> ChatSecure -> Signing. The old .xcconfig method doesn't seem to work well anymore.
ChatSecure.xcworkspace in Xcode and build.
Note: Don't open the
.xcodeproj because we use Cocoapods now!
