Question

This line of code causes compiler to complain and enter a debug mode

NSLog(@"Attacker card: %@", [attackerCard suit]);

I wonder whether it is due to the fact that suit is an enum value declared as

@property (assign) Suit suit;

Where Suit is declared as

typedef enum {
    CLUBS, DIAMONDS, HEARTS, SPADES
} Suit;

Am i doing something wrong with the format or, the problem lies elsewhere?

Answer 1

The specific size of an enumerated type is implementation defined but it’s always an integer type, so %d will work most of the time. If you need it to be very robust, you’ll want to test sizeof(Suit) and choose a format based on that.
