Programming Achievements: How to Level Up as a Developer

This gist is part of a blog post. Check it out at:

	#import "CoreDataTableViewController.h"

	@implementation CoreDataTableViewController

	#pragma mark - NSFetchedResultsControllerDelegate

	- (void)controllerWillChangeContent:(NSFetchedResultsController *)controller
	{
	[self.tableView beginUpdates];
	}

	import Foundation

	// MARK: - Comparable

	extension NSDecimalNumber: Comparable {}

	public func ==(lhs: NSDecimalNumber, rhs: NSDecimalNumber) -> Bool {
	return lhs.compare(rhs) == .OrderedSame
	}

	- (void)reloadFetchedResultsController {

	[NSFetchedResultsController deleteCacheWithName:@"Customers"];

	if (_request == nil) {
	_request = [[NSFetchRequest alloc] initWithEntityName:@"Customer"];
	}

	NSPredicate *predicate = [NSPredicate predicateWithValue:YES];
