Answer 1

You are not creating a new managed object for each Plant dictionary value. You are just trying to assign the dictionary itself to the relationship which, of course, will not work.

You need to add something like:

[gardenManObj setValue:[thisGardenDictionary objectForKey:@"rating"] forKey:@"rating"];

NSDictionary *thisGardenPlantsDictionary = [thisGardenDictionary objectForKey:@"plants"];
NSLog(@"thisGardenPlantsDictionary contains %i dictionaries.", [thisGardenPlantsDictionary count]);
NSManagedObject *plantMO;
for (Plant *eachPlant in thisGardenPlantsDictionary) {
  plantMO=[NSEntityDescription insertNewObjectForEntityForName:@"Plant" inManagedObjectContext:context];
  [plantMO setValue:[eachPlant valueForKey:@"someValue" forKey:@"someKey"]];
   //... repeat for all attributes
  [plantMO setValue:gardenManObj forKey:@"gardent"];
}

... that will create the necessary Plant objects and set the relationship with the correct Garden object.
