In previous installments of this series we laid out our state mocking system, and how we built UI integration testing on top of it. In this article we go into depth on how the system is architected, how idle detection is approached, and how errors are gracefully handled. This includes a fair amount of implementation […]

In today’s installment of my continuing series on using iCloud with Core Data I’m going to discuss how factors beyond your control may render iCloud unusable, even if everything is working normally. Even if everything is working correctly, the current API can still require complex workarounds to get decent app performance. Through this, keep in […]
Today I’m continuing my series of iCloud/Core Data-related posts with a discussion of duplicate data, how and why it occurs, and what you can do about it in your apps.
