In this chapter, we learned about the benefits of using iCloud, and how to access them through their storage APIs. We looked at how we can incorporate iCloud features within our code, how to store and retrieve key-value data, and how to store documents within a folder inside our application sandbox.
We also learned about the process involved in how to search and locate a document within an iCloud repository, as well as learned to handle and avoid file-version conflicts when multiple copies of the same file are being updated on more than one device, and then being submitted to the iCloud repository.
In the next chapter, we will learn about the new debugging features of OpenGL ES, and how this new debugger in Xcode allows you to track-down issues specific to OpenGL ES directly within your code, right from within the IDE.
