This is a real support request: Hi developer, I really hate how you have to pay for more minutes I was wondering if you could update to do surveys also as a way of paying? The mental model of this individual is astounding: How do I eat a survey, or use it to buy computing [...]
The Problem You may be interested in how to wire up or sync CoreData to a remote web service. There are plenty of frameworks to do this, like RestKit, RestfulCoreData, and various defunct libraries (CoreResource, etc.) The problem with these libraries is twofold: They assume things about your backend (like “It’s REST!” or “It has [...]

By now, you’ve certainly heard about Siri. It’s a very cool piece of tech. So cool, in fact, that I think it represents a big leap for Apple. The narrative we got from Phil Schiller is that for years, the programmers have taunted users with the dream of voice recognition technology that actually works, and [...]

Navigate to your project’s .xcodeproject file in Finder. Right-click, choose “Show Package Contents.” Leave the project.pbxproj file, but delete [...]

So I get about a couple people a day, 365 days a year, who inquire about my services. I’ve cataloged a few thousand inquiries at this point (99% don’t pan out, obviously). An awful lot of these [...]
