This allows you to only pull up a smaller portion of the objects in your data set that may result from your fetch request, allowing you to have smaller chunks of data as you go through your data set and also another candy feature of NSFetchRequest is relationship prefetching. Simply use an NSFetchRequest and give it a predicate to find the objects you're looking for. Now, as you ingest objects, your relationships will be changing and Core Data will maintain these for you, so if you set up any delete propagation rules in your object model we'll delete and object and propagate those deletes as you define.įinding objects in your object graph is also particularly easy. Simply tell us a bit about your Cocoa model there and the object model editor, tell us a little about your objects, their attributes, how they're all related to each other and we'll take care of the rest and we'll also persist it in the back end of your choice, be it sequel light or your own custom store. Well, Core Data makes this easy.Ĭore Data will manage your object graph for you. And then as your user makes changes on the UI you're pushing all those changes back through your object graph and back to your data source. Now as you process those objects you're building up a complex graph and shuttling all those changes to your UI. Now a lot of you have made these amazing apps with beautiful UI and you've tied it all with data that you're either getting from an external data source or provided with your resource bundle. My name is Rishi Verma and I'll be joined by Scott Perry later and we'll be presenting What's New in Core Data this year.īefore we get into what's new though, I'd like to tell you a little bit about what is Core Data. Delete these two pieces and you have a shorter but more coherent WWDC keynote.Good afternoon and welcome to Session 220. They inserted a baseball segment early and added a music segment at the end. They had them lined up but then one of them balked, leaving the WWDC produers scurrying to change the show. Apple planned to shake up the TV industry by securing sweeping partner agreements. The graphic logo for the event seemed to telegraph it. I believe the “one more thing” final segment was meant to be the long-awaited Apple TV, very relevant both to the developer audience as well as to kibitzers like the media.
Why?īecause, originally conceived as a stand-alone event, Apple Music was appropriated at the eleventh hour to fill out the keynote session after the original ending had to be scuttled. Instead it was shoehorned into a developers’ conference usually tightly focussed on code and operating systems. What was your WWDC 2015 highlight and lowlight?īecause WWDC 2015 seemed a strange mishmash, I persist in thinking that it was in fact cobbled together at the last minute.Īttempting to reshape the music industry-for a second time-shouted for its own special media event. For others, it’s watchOS 2, or the Apple Pay enhancements, or Apple’s News app…
Perhaps, instead of unveiling it at WWDC, there should have been a separate Apple Music event? It seems evident that the ongoing saga of Apple TV content deals (or lack thereof) impacted the WWDC 2015 keynote.įor some people, Swift 2 will be the highlight of WWDC 2015. It has the capacity to become very big, very quickly, and Apple could usher in yet another sea change for yet another industry. MacDailyNews Take: WWDC 2015: From triumphs to train-wrecks, and a different experience for everyone.įrom our perspective, “One more thing…” was desecrated by unfocused, unprepared presenters, but Apple Music certainly has the capacity to be worthy of the designation. Tons more in the full article – recommended – here. “And as much as everyone has spoken about the new Apple, that clash of culture will be a challenge for all of us.” “It was also about comedic bits and musical guests that proved far more divisive with the traditional audience than any new operating system or feature set ever has,” Ritchie writes. “It was about showing what that redesign and functionality will enable for the future.” This year it was more than pixels or bits,” Ritchie writes. In 2014 it was the functional revolution. “But the ramifications of what gets announced and how, and the effects it will have on us for the next year, takes me some time to come to grips with.” We shared some more midweek during the Debug Roundtable,” Rene Ritchie writes for iMore. We shared our initial reactions to WWDC 2015 right after Monday’s keynote on iMore Live from AltConf (video should be available soon).
