Is the official WWDC app available as a sample app? It'd be useful to learn CloudKit programming.
Source code for WWDC app?
The WWDC App is not available but was dicussed in session 226 Advanced NSOperations.
In a follow-up discussion I had at CloudKit Labs shortly after Session 715, CloudKit Tips and Tricks, I discovered there is no reference app for CloudKit. Instead, I was directed to refer to the Sample Code discussed in session 226 Advanced NSOperations. The Sample Code is called Earthquakes.
Unfortunately, I've not been able to get that to run correctly using XCode 7 and IOS 9. It runs on my device but doesn't do anything upon launch except to show an empty UITableView. A refresh swipe results in a crash.
Update:
I've been able to run the Earthquakes App in the Simulator. As I mentioned, it was recommended for some of the ways it uses NSOperation together with CloudKit.
The App still opens to an empty UITableView but the drag to refresh gesture seems to run correctly. I am seeing the the Network Activity indicator is still active after the UITableView data has been loaded.
