iOS Objective-C Basics (Retired) Foundation Framework NSArray

NSArray and for in

Getting an error I can't seem to fix. Any suggestions?

Challenge Question: Create a "for in" loop to iterate over drinks and print out each drink name using NSLog.

Error: Bummer! You didn't use the correct format specifier.

Code I used:

NSArray *drinks = @ [ @"juice", @"water", @"coffee" ]; for (NSString *string in drinks) { NSLog (@"&@", string); }

you need to use %@ not &@

for (NSString *string in drinks) {
    NSLog (@"%@", string);
}

Awesome. Thanks!

I'm having the same issue -

For (NSString *string in drinks) { NSLog(@"%@",string); }

you need to be sure you use a lowercase f on for:

I passed using your code with a lowercase f:

NSArray *drinks = @[@"juice", @"water", @"coffee"];

for (NSString *string in drinks) { NSLog(@"%@",string); }
