Unused variable warning
Hey, this is what I've coded so far in my "magic ball" app. http://imgur.com/zjJKO9B
As you can see, there is a warning in there. The app still functions, but I'm wondering what what warning is trying to get me to do.
Thanks for any help! Louis
Hi Louis, XCode is letting you know that you defined an array called predictions but you never used it.
