Swift index error

I'm getting error like this 'fatal error: Array index out of range'.

Here is my code:

init (index: Int) {
        let brandsLibrary = BrandsLibrary().library
        let playlistDictionary = brandsLibrary[index]
        brand = playlistDictionary ["brand"] as! String!
        clas = playlistDictionary["class"] as! String!
        headquaters = playlistDictionary["headquaters"] as! String!
        models += playlistDictionary["models"] as! [String]        
    }

Can somebody please help me how to get rid of this error?

"index out of range" means you are trying to access an item in your array that is outside the bounds of the array. I.e., if you are trying to access item 6 of an array that only holds 4 items, your app will crash because the array doesn't hold 6 items.
