Or if you own an Apple TV there’s a dedicated WWDC 15 channel you can tune in to so you can watch the event on the big screen.

If you’re keen on watching the keynote, you can simply visit from your Safari browser on your Mac or iOS device and catch the live stream that way. Luckily, as has been the case for a few years now, Apple will be live-streaming the keynote so you don’t have to smash your way through a wall of humanity in order to watch the event yourself (if you were even able to get a WWDC ticket, that is). The line to get into the Moscone Center here in San Francisco was a formidable one, and the sheer amount of news and satellite trucks parked out front is a good indication that this is a pretty big deal.
And if we’re lucky, they might even talk a little bit about gaming. It’s also possible Apple will announce a new music streaming service at the keynote. Every year there’s buzz about Apple finally refreshing the Apple TV and opening the little box up to developers, but this year those rumors seemed to get squashed early on, so we’ll see.
And hey, there just might even be a few surprises. They’ll most likely be talking about the current state of Apple’s business, unveiling what they have planned for iOS 9, and laying out what sort of sessions developers can partake in during WWDC this week. NSOperations stem from the NeXTSTEP era, and while they can be used in modern applications, today I think they’re simply a bit… clunky.Apple’s World Wide Developers Conference kicks off this morning as it does every year with Apple delivering a keynote address. Or I’d do something like Async/Await with Result and GCD. Both are uniquely suited to handling sequential streams of events and operations, and I get automatic propagation of my data and better error handling to boot. If I needed to do something today like your import/upload example, I’d probably reach first for RxSwift or Combine. I believe that one of the reasons operation-based development didn’t catch on is that we simply have better solutions available. If an operation fails how do you get the error back out of it? You can, of course, but again with the drawback of adding additional complexity, especially when chaining multiple failable operations.įinally.
You could add a factory to provide operations and use protocols to also provide “mock” instances for testing, but now we’ve added quite a bit more complexity simply to support operations.Īnother issue is error handling and perhaps more to the point, error reporting.

Tight coupling between components and added difficulty when it comes time to test the code that uses those operations. A service could build them and use them…īut directly instantiating an operation from within has many of the same drawbacks as directly accessing singletons. This makes them unsuited for direct dependency injection as opposed to a service. And I did… and in the course of doing so I found that they suffer from a few drawbacks.įirst and foremost is that once an operation has executed you need another one. That said, when I first saw the Advanced NSOperations video I was excited and wanted to use them.
One guess as to which one generated the most interest?
