SRCoreDataStack is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod "SRCoreDataStack"


To run the example project, clone the repo, and run pod install from the Example directory first.

Get the default shared instance:

self.dataStack = [SRCoreDataStack defaultStackForDataModel:@"Example"];

Save objects coming from network call into Core Data:

[self.dataStack saveObjects:wireObjects deleteNonMatchingLocals:NO inEntity:@"Movie" withWireAttribute:@"id" andLocalAttribute:@"movie_id" andConfiguration:^NSManagedObject *(NSDictionary *obj, NSManagedObject *mo, NSManagedObjectContext *currentCtx) {
   Movie *movie = (Movie*)mo;
   movie.movie_id = obj[@"id"];
   movie.movie_title = obj[@"title"];
   movie.movie_description = obj[@"description"];

   // define its parent-child relationship
   NSMutableArray *ma = [NSMutableArray array];
   for (NSString *genreString in obj[@"genres"])
      MovieGenre *movieGenre = [MovieGenre insertNewObjectIntoContext:currentCtx];
      movieGenre.genre_name = genreString;
      [ma addObject:movieGenre];
   movie.movie_genres = [NSSet setWithArray:[NSArray arrayWithArray:ma]];
   return movie;

Example project

Example project uses this backend project. The backend project, once downloaded and run on Terminal, can be viewed through browser. You can then make seamless live synching between the apps.


  • Saves wire objects in background managed object context
  • Custom object serialization and relationship management between objects handled within a block
  • Under the hood works with NSManagedObject instances, thus the stack doesn’t need to know of your custom managed object type
  • Uses nested managed object contexts for synching
  • Implements "insert or update" algorithm discussed in WWDC 2013-211 video
