I am trying to setup my Core Data database for use with iCloud, I understand the basic and followed a nice tutorial on how to set it up, does anyone know what might be going wrong?
I am getting the error that the database could not be connected to:
Unresolved error: Error Domain=NSCocoaErrorDomain Code=256 "The operation couldn’t be completed. (Cocoa error 256.)" UserInfo=0x1c5de2a0 {NSUnderlyingException=unable to open database file, NSSQLiteErrorDomain=14}, {
NSSQLiteErrorDomain = 14;
NSUnderlyingException = "unable to open database file";
}
Here is my code to return the persistent store:
- (NSPersistentStoreCoordinator *)persistentStoreCoordinator
{
if (__persistentStoreCoordinator != nil) {
return __persistentStoreCoordinator;
}
NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"CategoryModel.sqlite"];
NSError *error = nil;
__persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]];
if (![__persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:nil error:&error]) {
/*
Replace this implementation with code to handle the error appropriately.
abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development.
Typical reasons for an error here include:
* The persistent store is not accessible;
* The schema for the persistent store is incompatible with current managed object model.
Check the error message to determine what the actual problem was.
If the persistent store is not accessible, there is typically something wrong with the file path. Often, a file URL is pointing into the application's resources directory instead of a writeable directory.
If you encounter schema incompatibility errors during development, you can reduce their frequency by:
* Simply deleting the existing store:
[[NSFileManager defaultManager] removeItemAtURL:storeURL error:nil]
* Performing automatic lightweight migration by passing the following dictionary as the options parameter:
[NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil];
Lightweight migration will only work for a limited set of schema changes; consult "Core Data Model Versioning and Data Migration Programming Guide" for details.

Here is my managedObjectModel method (CategoryModel is the name of the .xcdatamodeld):
- (NSManagedObjectModel *)managedObjectModel
{
if (__managedObjectModel != nil) {
return __managedObjectModel;
}
NSURL *modelURL = [[NSBundle mainBundle] URLForResource:@"CategoryModel" withExtension:@"momd"];
__managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL];
return __managedObjectModel;

When I try downloading the file from developer.icloud.com, it does not download and a message is sent to the Safari console Failed to load resource: the server responded with a status of 409 (Conflict)
When a file is uploaded, several warnings are issued in the Safari console:

Edit [whatever number it is now]
When logging the persistent stores, NSLog(@"MOC: %@", self.managedObjectContext.persistentStoreCoordinator.persistentStores);
I get the following output:
2013-03-02 13:57:38.241 Clueless[2221:907] MOC: (
"<NSSQLCore: 0x1c5da560> (URL: file://localhost/var/mobile/Applications/[some long number which looks like it should be private]/Documents/CategoryModel.sqlite)"
)
So Im guessing the error unable to connect to database is called because only the local persistent store is there
New error
Safe save failed for file, error: Error Domain=NSCocoaErrorDomain Code=512 "The file upload timed out." UserInfo=0x1c5cb220 {NSLocalizedDescription=The file upload timed out.}
Edit - error with directory
I think the issue is with a directory not being created.
The following log says a directory is not there, when trying to transfer a file. I think should I be able to fix this, iCloud will work:
