Ugh… SceneKit is both promising and frustrating. It appears to be a very stereotypical case of “version 1” syndrome – nice idea, flaky implementation and very skimpy documentation. So amongst the many strange, undocumented foibles it has, one in particular is quite egregious. When you add an SCNNode to your SCNView-rendered scene, containing an SCNCamera, the… Read more

The answer is pretty easy to find. The relevant code follows a similar… Read more
I’ve been trying to make use of iCloud in an iOS app over the last couple of weeks, and it’s been absolutely infuriating. There’s a large volume of documentation, but it’s not very good, and it’s incomplete. So let’s run down the laundry list: Entitlements Getting the entitlements to work is, in general, an incredible… Read more
