The Objective-C religion doesn't allow to insert Integers into NSDictionary

So...

// why they've done so with old good enums?
typedef NS_ENUM(NSUInteger, PaymentType) {
    tCreditCard  = 0,
    tBankAccount = 1,
    tBitcoin     = 2
};

        ...

NSDictionary *payItem = [[NSDictionary alloc] 
                        initWithObjectsAndKeys:[NSNumber numberWithInt:tCreditCard], @"type", 
                        [self makeFakeCreditCardData], @"data", nil];

        ...

switch([[object valueForKey:@"type"] integerValue])
{
    case tCreditCard:
        // do something
        break;

        ...
