Written by 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 […]
From the README on github: 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. Please note that momcom is experimental. Although it is intended to be at least as […]
From the README on github: 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 […]
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 previous post in this series, today I’m sticking to how things are supposed to work and sometimes actually do. The problem of […]
It’s almost time for iOSDevCamp Colorado! iOSDevCamp is 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. Three weeks from today! This is the fourth […]
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 […]
Update: This post is old but still accurate as far as comparing JSON with property lists, with examples for Objective-C code. If you’re using Swift, see my newer post that updates this one for Codable and Swift examples. Mac OS X and iOS include support for JSON and property lists, two generic structured data formats, […]
“Don’t you just turn on iCloud syncing, and it all Just Works?” “Just works” might be the customer experience; but developers must do more to support iCloud (or any new OS technology) than simply flipping a switch. Things can go wrong, and they often do. Rich gets into a lot more technical detail than most […]
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 […]
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 […]
