Early this year I mentioned a great open source project providing a straightforward universal API for working with various app analytics programs called ARAnalytics.
Here’s another interesting project from Orta in the form of a Ruby Gem that allows you to save the an app’s current state in the iOS simulator including all data thus saving you from the need to constantly sync and resync app data.
As stated on the Artsy engineering blog:
Chairs is a gem you can install via gem install chairs. It allows you to stash and replace your current iOS simulator application state. It will grab everything related to the app ( including the current NSUserDefaults) and store it in a named subfolder in your current working directory.
You can find Musical Chairs on Github here.
You can read more about Musical Chairs on the Artsy Engineering blog.
An extremely handy tool to have around if you’re working on an app that requires you to store large amounts of data.
