Is it %d or %@ ?

I was having a problem with this question and found a forum posts with help documenting how to answer using %d when my version clearly asks me for %@.

Has the question been updated? because my answer of:

NSNumber *foxtrot = @24;

NSLog(@" %@", foxtrot);

NSNumbers are objects, so you need to use %@ which is the format specifier for objects. %d is only used for ints.

The reason you arent passing is your string is incorrect. It needs to output this: foxtrot 24 currently all you are outputting is 24
