can't get UIImage's init(contentsOfFile:) to work

I am trying to locate a file in a subdirectory of subdirectory of my bundle. I used this code to create an UIImage with init(contentsOfFile:).

let resource = NSBundle.mainBundle().pathForResource("1g", ofType: "jpg", inDirectory: "Level1")      
let image = UIImage(contentsOfFile: resource!)

What am I doing wrong?

EDIT:

This works because groups you create in xcode editor do not affect the actual path.

let resource = NSBundle.mainBundle().pathForResource("1g", ofType: "jpg", inDirectory: nil)

or let resource = NSBundle.mainBundle().pathForResource("1g", ofType: "jpg")

you are get the error fatal error: unexpectedly found nil while unwrapping an Optional value, this means your variable is set to nil, but your code is expecting it to not be nil.

do like check the resource contains value or not.

let resource = NSBundle.mainBundle().pathForResource("1g", ofType: "jpg", inDirectory: "Level1") print (resource) //

then

do like

Choice -1

if let resource = NSBundle.mainBundle().pathForResource("1g", ofType: "jpg", inDirectory: "Level1") 

{
  let image = UIImage(contentsOfFile: resource!)
}
else
 {
 print (resource)
 }

Choice -2

let resource = NSBundle.mainBundle().pathForResource("1g", ofType: "jpg", inDirectory: "Level1")      

if resource != nil {
//Do Something
let image = UIImage(contentsOfFile: resource!)
}

Ok I figured it out. Based on the path Fatti Khan mentioned I tried 

let resource = NSBundle.mainBundle().pathForResource("1g", ofType: "jpg",inDirectory: nil)

which is the same as 

let resource = NSBundle.mainBundle().pathForResource("1g", ofType: "jpg")

It seems that even though I created groups in xcode editor that had no effect no the actual path, which is: file:///Users/user/Desktop/MattNeuburg/pathFinder/pathFinder/1g.jpg. pathFinder is the name of the project.
