Remove Core Data from an Xcode project

Question

I started an app development using Core Data in the course of the development of the project I have been observing that the Core Data is not the best for the app.

Within this scenario, I would like to know how I do to remove Core Data completely of my application and continue the development of the same without it.

Since you didn’t specify whether it’s Swift or Objective-C, I’ll guess it’s Objective-C. But the process on Swift is similar.

1. Select the project on Project Navigator -> Build Phases and in Link Binary With Libraries remove the CoreData.framework
2. (Skip this step if you are Swift) Search for the . pch file of your project. Usually the default is: [Name of your project]-Prefix.pch. Remove the line from #import <CoreData/CoreData.h>
3. Delete any file *.Model

4. In the AppDelegate.h delete the following properties and methods (On Swift are the lazy var eponymous):

   • @property (readonly, strong, nonatomic) NSManagedObjectContext *managedObjectContext; @property (readonly, strong, nonatomic) NSManagedObjectModel *managedObjectModel; @property (readonly, strong, nonatomic) NSPersistentStoreCoordinator *persistentStoreCoordinator;
   • - (void)saveContext;
- (NSURL *)applicationDocumentsDirectory;

5. (Skip this step if you are Swift) No AppDelegate.m remove the @synthesize of the properties you have just removed:

   • @synthesize managedObjectContext = _managedObjectContext; @synthesize managedObjectModel = _managedObjectModel; @synthesize persistentStoreCoordinator = _persistentStoreCoordinator;

6. Still in the AppDelegate.m delete the following methods:

   • saveContext managedObjectContext managedObjectModel persistentStoreCoordinator applicationDocumentsDirectory
7. And finally, still in AppDelegate.m, within the method applicationWillTerminate remove the call from the method [self saveContext]

Okay, you got rid of Coredata!
