Help with 'build a weather app' challenge task

The task says, "Don't forget to instantiate the dictionary with the plist!" I have no idea where I am going wrong.

plist.swift 
import Foundation

// Add your code below


let plistPath = NSBundle.mainBundle().pathForResource("CrazyInformation", ofType: "plist"),
let informationDictionary = NSDictionary(contentsOfFile: plistPath)

Hi Aniket

Your first line ends with a comma, which will certainly not work :) However, if you meant to end it with a bang (!) to unwrap the returned path, then you are not wrong. But in doing so you risk a crash if pathForResource returns nil. If you implement an if-let statement, and only populate the dictionary if you actually get a valid path back from pathForResource, then you should be able to move on...

Need specifics? I prefer not to type out the solution.

Thanks a lot Rasmus, I figured it out.
