Does the preview button work? I've rarely actually see any results when using. Tend to see a blanks screen

Is the 'Preview' button suppose to work? Or am I suppose to use a certain browser and setting to get this working? Im using Chrome latest version.

array.swift 
// Enter your code below

var arrayOfInts: [Int] = [1, 2, 3, 4, 5, 6]

arrayOfInts.append(7)

arrayOfInts = arrayOfInts + [8]

let value = arrayOfInts[4]
