Great work, now the next big thing is to mix this with Cocoapods to that once you select a package, it does the pod install command for you automatically and you are good to go.
Alcatraz isn't a CocoaPods wrapper, it is an installer for Xcode customizations like plugins and color schemes. You can use it to install a CocoaPods Xcode plugin to handle installing and updating pods though: https://github.com/kattrali/cocoapods-xcode-plugin
