UIImagePicker Controller swift

Question

Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates

I'm getting this warning when I used UIImagePickerController to take photo from camera.and couldn't set image to image view

Please follow the code and apply in your project according to the relevant place

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.")
}
