Only a few pages into the iOS Security document released by Apple today, and already there’s a notable error. It states: Apps can’t share data directly with each other; sharing can be implemented only by both the receiving and sending apps using custom URL schemes, or through shared keychain access groups. False, at least partially.… Read more
I’ve wanted to try out a few little projects based around llvm/clang for a while now. I grabbed the sources from svn last week, and have been perusing them, and their documentation, randomly. Today I caught wind of the supposed support for Xcode (in the form of Xcode project files) via CMake. “Awesome!”, I thought,… Read more
It should be a trivial task. It’s certainly an obvious goal, and I was quite perturbed to find no clear instructions, very little discussion of it at all, and a few awkward speed-bumps on the way. But I did figure it out. So here it is, for those lucky enough to find this before they… Read more

So now anyone using an old link to any HTML page under https://homepage.mac.com/wadetregaskis will get… Read more
I had a devil of a time trying to get Xcode to recognise my standard Core Data UIManagedDocuments, given they are bundles, not flat files. Turns out one of the keys was that your UTI must inherit from com.apple.package. I had rather more sensibly (IMHO) inherited from one of the built-in database UTIs. Silly me for… Read more
