I’m mostly putting this up here to make it easy for me to find later.

Brent Simmons has been writing a great bunch of articles on syncing between a client app and a web service as he adds syncing to Vesper. I’m tackling something similar at the moment, and the insights in there have been a huge help.

(I’m leaving out the Core Data ones, because I’m interested more in the communication between the server and app, not how the app’s storing things.)

Bonus: objc.io put out an issue on syncing too!
