Core Data And Swift

Been quite a while since the last time we rounded up Core Data goodies, since when we’ve gone through The iCloud Angst Apocalypse and ended up with that class of problem being relegated to the new CloudKit hotness … if you don’t need, like, cross-platform access or anything. Which most people want. As, indeed, we’re going to be designing the iOS side of a project in that cross-platform space next week; so let’s take a look at what’s going on now in the new Swifty iOS 8 world, shall we?

First off, here’s an decently comprehensive curation of important tools as the Swift world dawns — keep an eye on all of these to see how they adapt to new world Swiftiness:

Top 10 Core Data Tools and Libraries :

Marcus Zarra gives us The Core Data Stack In Swift

Like videos? There’s a bunch here.

UPDATES:

AERecord: ”Why do we need yet another one Core Data wrapper? You tell me!”

(h/t ManiacDev) AlecrimCoreData: “a Core Data wrapper library written in Swift, “inspired” by MagicalRecord and LINQ.”

JSQCoreDataKit: “A swifter Core Data stack.” — rewrite of RSTCoreDataKit

QueryKit is a nifty Core Data query language in Swift; also check out KFData for some convenient Objective-C conveniences

SugarRecord: “…you’ll be able to start the CoreData stack structure just with a line of code and start working with your database models using closures thanks to the fact that SugarRecord is completly written in Swift.”

SuperRecord: “A small set of utilities to make working with CoreData and Swift a bit easier.”

CoreDataSwagger: “Extensions for CoreData on iOS.”

CoreDataKit: “makes common operations on objects and importing into CoreData a breeze.”

    I made this new Core Data wrapper for iOS in Swift - https://github.com/tadija/AERecord You can use it to setup Core Data stack like this: AERecord.setupCoreDataStack() Access context for current thread like this: AERecord.defaultContext Save context like this: AERecord.saveContext() Create fetch requests like this: NSManagedObject.create() NSManagedObject.firstOrCreateWithAttribute("city", value: "Belgrade") NSManagedObject.deleteAll() let predicate = ... NSManagedObject.firstWithPredicate(predicate) NSManagedObject.allWithAttribute("year", value: 1984) And much more... I hope it will be useful for someone.
