DDLogVerbose is a function from CocoaLumberjack. Your best bet to make this easy would be to install SVGKit via CocoaPods. To do so, first install motion-cocoapods
sudo gem install motion-cocoapods
This should install cocoapods and motion-cocoapods. You need to setup cocoapods so run
pod setup
Now you can add motion-cocoapods to your Gemfile
gem 'motion-cocoapods'
Next add the pod to your rake file
app.pods do
pod 'SVGKit'
end
Finally run the following rake command to download SVGKit
rake pod:install
Next time you rake, everything should theoretically just compile and work! Good luck :)
