Oh man, I have waited a long time for a tool like this to come around. I've even attempted to build one myself a couple times.
The process of localizing Cocoa applications has always been a bit of a chore. Various tools are available to facilitate localization of applications, but they all require a fair amount of work. Even when there is demand for localization, many applications are only available in one language. Greenwich is here to change that.
Greenwich is a new, open-source framework that greatly speeds up the process of localizing and translating an iOS or Mac app. At anytime a developer or translator (yep, Greenwich has been built with translators in mind) can make a change to a word or two, relaunch your app and see the changes reflected immediately.
Setup and usage for iOS and
Mac are very well documented on Greenwich's awesome setup page.
Do yourself a favor and check this out now, if you've ever localized a Mac or iOS app you know what a pain the process can be. Looks like we finally have a great solution.
