Core data migration error Cocoa error 134130 Can't find model for source store

Question

My app is live on the app store. I made an update with changes to the core data model. I followed the core data light migration on Apple dev website.

• Add a new version of the model in Xcode
• Make changes to the new model version
• Select the option to use the new version for the model (new model version has the green check)
• Add options when add sqlite file to the persistent store

Here is the code:

NSString *momdPath = [[NSBundle mainBundle] pathForResource:@"PropertiesModel" ofType:@"momd"];
    model = [[NSManagedObjectModel alloc] initWithContentsOfURL:[NSURL fileURLWithPath:momdPath]];

//    model = [NSManagedObjectModel mergedModelFromBundles:nil];

    psc = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:model];

    NSString *path = [self itemArchivePath];
    NSURL *storeURL = [NSURL fileURLWithPath:path];

    NSError *error = nil;
    NSDictionary *options = @{ NSMigratePersistentStoresAutomaticallyOption : @(YES),
                               NSInferMappingModelAutomaticallyOption : @(YES),
                               NSSQLitePragmasOption : @{@"journal_mode" : @"DELETE"}};
    if (![psc addPersistentStoreWithType:NSSQLiteStoreType
                           configuration:nil
                                     URL:storeURL
                                 options:options
                                   error:&error]) {
        CLS_LOG(@"store URL: %@ \n options: %@ \n error: %@",storeURL,options,error);
        [NSException raise:@"Open failed" format:@"Reason: %@, Full Error: %@", [error localizedDescription],error];
    }

    // Create the managed object context
    context = [[NSManagedObjectContext alloc] init];
    [context setPersistentStoreCoordinator:psc];

I keep running into this error that it cannot find my original (old version) model. The weird thing is when I tested it during development, it worked. I released to the app store and now it is crashing on all my user's device.

I tried to revert back to the code base of the last stable release version in the app store but I also runs into a core data error "the model is not compatible with the store" or something like that.

This is driving me nut. Could someone shed some light on this issue please?

Edit: My app can back up core data files to dropbox. It backs up the sqlite file and -shm and -wal files. If i delete my app and download the current version on the app store, restore the 3 files from dropbox, go to any screen that uses core data, it will crash.

Is there an easy way I can export the data from the sqlite and import it to core data with the new model?

Answer 1

I was able to get the correct old data model by checkout a commit way in the past and fix the issue. Thanks all
