Fixing the "contains is unavailable" error in Swift 2.0

[kjmcneish]

The contains() method has been removed from Swift 2.0, and has been replaced with the contains() method found on collections instead.

For example, this code in Swift 1.2 and earlier:

Code: [Select]

let fruit = ["Apple","Orange","Banana"]
let hasApple = contains(fruit, "Apple")
Should be changed to:

Code: [Select]

let fruit = ["Apple","Orange","Banana"]
let hasApple = fruit.contains("Apple")
All the best!
