iCloud Complications, Part 3: I'm Waiting...
May 7, 2013
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 mind that as with my previous post, I’m sticking to how the API is designed to work in the absence of bugs in the implementation.

momcom is a command-line tool for Mac OS X that takes an uncompiled Core Data model created with Xcode and compiles it to produce a compiled '.mom' or '.momd' suitable for use at run time.

momdec is a command-line tool for Mac OS X that takes a compiled Core Data model and decompiles it to produce an equivalent xcdatamodel or xcdatamodeld suitable for use in Xcode. The resulting model file can also be used with mogenerator to produce source code files for Core Data entities which have custom subclasses.
iCloud Complications, Part 2: De-duplication
Apr 15, 2013
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. As with my (link:/icloud-complications text:previous post) in this series, today I’m sticking to how things are supposed to work and sometimes actually do.
The problem of duplicate data isn’t actually specific to iCloud. It can happen in any case where people might create data on different devices and where your app wants to sync that data between the devices.
iOSDevCamp Colorado 2013
Apr 12, 2013
It's almost time for iOSDevCamp Colorado, an informal un-conference where anyone is welcome and encouraged to present about anything relevant to iOS development. Colorado has a fantastic iOS developer community and these events are a great place to meet people, learn things, and have fun.
iCloud Complications, Part 1
Apr 9, 2013
As (link:/blog/icloud-sotu text:promised), I’m going to be doing a number posts on using iCloud with Core Data. I’m not sure how many there will be, I’ll keep going as long as it takes. Today I’m starting off with some things that, while not actually bugs, may catch a developer off guard. In this post I’m sticking to how iCloud is designed to work, and not getting into the questions of how and when it doesn’t work.
JSON and Property Lists: Alternate Universe Siblings
Apr 3, 2013
Mac OS X and iOS include support for JSON and property lists, two generic structured data formats, both in common use in different places. If Stack Overflow is any indication, there’s a fair amount of confusion regarding the two. It’s true, they’re very similar, so much that it’s tempting to think the differences are merely syntax choices. In some cases it’s possible to read data from one format and write it to the other as-is, with no conversion.
Rich Siegel on iCloud

“Don’t you just turn on iCloud syncing, and it all Just Works?” Rich gets into a lot more technical detail than most of the other iCloud coverage that's come out recently.
iCloud: State of the Union
Mar 27, 2013
As some of you know, I’ve spent a lot of time over the past year working with iCloud in Mac and iOS apps. Specifically, working with Core Data’s built-in support for iCloud. I’m going to be doing a series of blog posts covering iCloud in various ways. Today I’m going to start off with an overview covering how iCloud is supposed to work with Core Data and a little about how it actually works in practice.
Waiting for WWDC
Mar 17, 2013
Once upon a time Apple would announce dates for their World-Wide Developer Conference and those of us who were interested would calmly begin planning our trip. The only urgency came from making sure to buy a ticket in time to get the earlybird price.
Those were the days. Now, the announcement of WWDC dates triggers a mad rush to buy tickets before they’re gone. Don’t hesitate, don’t think, or the decision is made for you.
