Storm (i)Cloud

Last year I did a series of posts here where I ran through problems I had encountered with Core Data’s iCloud integration, with various solutions and workarounds I had been able to devise. Then iOS 7 and Mac OS X 10.9 came out with numerous visible (and internal) updates and people started asking me, so, […]

Probably Approximately Correct Location for iOS

If you’re writing an iOS app and you need to know the user’s current location, the answer is straightforward: use Core Location. That fires up device GPS (when available). Apple’s A-GPS combines this with things like local Wifi networks and IP addresses to work out the device’s location. All of this, of course, assuming that […]

Mark Dalrymple on the Objective-C Run Time

iCloud Complications, Part 3: I’m Waiting…

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 […]
