Chatto

Chatto is a Swift lightweight framework to build chat applications. It's been designed to be extensible and performant. Along with Chatto there is ChattoAdditions, a companion framework which includes cells for messages and an extensible input component. You can find more details about how it was implemented in our blog. See them in action!

How to install

CocoaPods

1. Make sure use_frameworks! is added to your Podfile.

2. Include the following in your Podfile:

pod 'Chatto', '= 2.0.0'
pod 'ChattoAdditions', '= 2.0.0' # if you want to use the cells or the input component

If you like living on the bleeding edge, you can use the dev branch with:

pod 'Chatto', :git => 'https://github.com/badoo/Chatto', :branch => 'dev'
pod 'ChattoAdditions', :git => 'https://github.com/badoo/Chatto', :branch => 'dev'

3. ChattoAdditions won't compile with -O optimization due to https://bugs.swift.org/browse/SR-2223. Add the following post_install phase to your Podfile:

# workaround for https://bugs.swift.org/browse/SR-2223
post_install do |installer_representation|
  installer_representation.pods_project.targets.each do |target|
    if target.name == 'ChattoAdditions'
      target.build_configurations.each do |config|
        if config.name == 'Release'
          config.build_settings['SWIFT_OPTIMIZATION_LEVEL'] = '-Owholemodule'
        end
      end
    end
  end
end

4. Run pod install
