Use lazy instantiation to allocate and initialize this property (in the property’s getter)
so that it starts off with a full deck of PlayingCards.

Use the getter to check if there is a valid deck. If not, initialize one …

#import "PlayingCardDeck.h"
...
- (Deck *)deck
{
    if (!_deck) {
        _deck = [[PlayingCardDeck alloc] init];
    }
    return _deck;
}
