Can not get image from file

I have cache images in file like so:

enter image description here

I want to get these images, I have tried like this:

let documentsURL = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first!
let imagePath = documentsURL.absoluteString.stringByAppendingString("1.png")
let image = UIImage(contentsOfFile: imagePath)
print(image)


the imagePath give me:


"file:///Users/entropy/Library/Developer/CoreSimulator/Devices/3A41D467-B991-4F85-93CD-10C227ED4F69/data/Containers/Data/Application/F5005FAA-7107-41DD-86D2-38C302742063/Documents/1.png"


You see it gives me exactly the image path, but when I
print(image)
, the image is
nil
.

What I am doing wrong here. Please help me with this. Thanks.

Answer

Try this EDIT

let path = "~/1.png"
let expandedPath = path.stringByExpandingTildeInPath
let data = NSData(contentsOfURL: NSURL(string: expandedPath)!)

let image = UIImage(data: data!)
print(image)

Hope this helps.
