I can't seem to get a handle on this Array thing

For some reason, I try to get the Array right, but I failed. What could be the problem? (It's been a since I got on the iOS track.)

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

for (NSString *drink in drinks)
{
  NSLog(drink);
}

Hi there,

You can't output the drink to the log like that - you'll need to use interpolation. Try something like:

NSLog(@"%@", drink);

I hope that helps,

Steve.

Thanks, I wasn't so used to programming in Objective-C. I focused on every other programming language, since I was on my PC. (I'm on my Mac right now) Thanks, man.
