Answer 1

PFFile is a parse representation of anykind of file. To get the "real" file (image), you need to call getDataInBackgroundWithBlock. Try it:

if let userPicture = object.valueForKey("Image")! as! PFFile {
   userPicture.getDataInBackgroundWithBlock({
      (imageData: NSData!, error NSError!) -> Void in
         if (error == nil) {
            let image = UIImage(data:imageData)
            self.ImageArray.append(image)
         }
      })
}

With Swift 3 on Parse.

  if let photo = obj.file as? PFFile {
       photo.getDataInBackground(block: {
          PFDataResultBlock in
          if PFDataResultBlock.1 == nil {//PFDataResultBlock.1 is Error
                    if let image = UIImage(data:PFDataResultBlock.0!){
                        //PFDataResultBlock.0 is Data
                        photoCell.attachedPicture.image = image
                    }

                }
            })
        }

Swift 1.2+ Version

        if let userPicture = PFUser.currentUser()!.valueForKey("Image") as? PFFile {
            userPicture.getDataInBackgroundWithBlock {
                (imageData: NSData?, error: NSError?) -> Void in

                if error == nil {
                    let image = UIImage(data:imageData!)
                    self.ImageArray.append(image)
                }else{
                    print("Error: \(error)")
                }
            }
        }
