I will give you best understandable coding for pick the image,refer this

func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) 
{
     var alert:UIAlertController=UIAlertController(title: "Choose Image", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)
     var cameraAction = UIAlertAction(title: "Camera", style: UIAlertActionStyle.Default)
     {
        UIAlertAction in
        self.openCamera()
     }
     var gallaryAction = UIAlertAction(title: "Gallary", style: UIAlertActionStyle.Default)
     {
        UIAlertAction in
        self.openGallary()
     }
     var cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel)
     {
        UIAlertAction in
     }

    // Add the actions
     picker?.delegate = self
     alert.addAction(cameraAction)
     alert.addAction(gallaryAction)
     alert.addAction(cancelAction)
     self.presentViewController(alert, animated: true, completion: nil)
}
func openCamera()
{
    if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera))
    {
        picker!.sourceType = UIImagePickerControllerSourceType.Camera
        self .presentViewController(picker!, animated: true, completion: nil)
    }
    else
    {
        let alertWarning = UIAlertView(title:"Warning", message: "You don't have camera", delegate:nil, cancelButtonTitle:"OK", otherButtonTitles:"")
        alertWarning.show()
    }
}
func openGallary()
{
    picker!.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    self.presentViewController(picker!, animated: true, completion: nil)
}

//PickerView Delegate Methods
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject])
{
    picker .dismissViewControllerAnimated(true, completion: nil)
    imageView.image=info[UIImagePickerControllerOriginalImage] as? UIImage
}
func imagePickerControllerDidCancel(picker: UIImagePickerController)
{
    println("picker cancel.")
}

Have a nice day:-)
