2,553 PointsBuilding a music library model using NSDictionary
Hi, I am stuck on the below task. Any help would be greatly appreciated. Thanks!
Now that we have a chocolate box, let’s add some chocolates. We’re going to represent a single chocolate as an NSDictionary instance. Create an instance of NSDictionary, named caramelDelight and instantiate with the string flavor as a key and the string caramel as its value. Next, store the caramelDelight dictionary in the chocolateBox array.
#import <Foundation/Foundation.h>
@interface GiftBasket : NSObject
@property (strong, nonatomic) NSArray *chocolateBox;
@end
#import "GiftBasket.h"
@implementation GiftBasket
- (instancetype)init
{
self = [super init];
if (self) {
//Add your code below
}
return self;
}
@end

Courses Plus Student 5,806 PointsYou got the property, great, now add the NSDictionary instance called caramelDelight, this is how we do it:
NSDictionary *caramelDelight = @{@"flavor": @"caramel"};
the flavor is the key followed by a : then we insert the value which is caramel
to store the caramelDelight in the chocolateBox array we use the following syntax.
self.chocolateBox = @[caramelDelight];
