"local declaration of 'predictionArray' hide instance variable"

The problem happens when I'm in Xcode, I did just like what the instructor taught, then suddenly it appears yellow line and side by side of the code:

self.predictionLabel.text = [predictionArray objectAtIndex:5];

I'm in this lesson: http://teamtreehouse.com/library/ios-development/build-an-iphone-crystal-ball-app/learning-the-language/creating-a-property

someone can explain this to me. im in Xcode iOS 6.

Thanks, Amin

It's possible that you are declaring the predictionArray within that method. You need to remove that declaration since you have created a property within the header file. And since you have created a property you should refer to it with self.predictionArray
