Not sure how to create the for in loop

I've watched the video twice and I still don't understand how I'm supposed to create it.

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

Challenge Task 2 of 2

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

the use of for...in loop was covered in this lecture at around 03:40 time stamp.

The for...in loop you're going to write for this challenge is quite similar to what the instructor presented during the lecture. The difference is that now you have an Array of NSString instead of NSNumber.

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

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

Hope it helps.
