Create a "for in" loop to iterate over drinks and print out each drink name using NSLog.
NSArray *drinks = @[@"juice", @"water", @"coffee" ];
for (*drinks) {
NSLog("%@", drinks)
}

We're missing an '@' before that first argument to NSLog.
To have our for loop cycle through each element of our NSArray, we'll want to use the 'in' keyword. We'll write the condition of our for loop as if to say 'for each NSString element in drinks...', and then the rest of the loop tells the compiler what to do for each element.
NSArray *drinks = @[@"juice", @"water", @"coffee"];
for (NSString *drink in drinks) {
NSLog(@"%@", drink);
}
Hope this helps!
