Just to add to the above, For swift 3.0 this worked for me.

PHPhotoLibrary.shared().performChanges({
                let imageAssetToDelete = PHAsset.fetchAssets(withALAssetURLs: imageUrls as! [URL], options: nil)
                PHAssetChangeRequest.deleteAssets(imageAssetToDelete)
            }, completionHandler: {success, error in
                print(success ? "Success" : error )
            })

Thanks for the help.

Fixed it with the below code.

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    let image = info[UIImagePickerControllerOriginalImage] as! UIImage
    pickedImage = image
    saveImageToDisk(pickedImage)
    refreshCollectionView()
    let imageUrl = info[UIImagePickerControllerReferenceURL] as! NSURL
    var imageUrls = [imageUrl]
    //Delete asset 
    PHPhotoLibrary.sharedPhotoLibrary().performChanges( {
        let imageAssetToDelete = PHAsset.fetchAssetsWithALAssetURLs(imageUrls, options: nil)
        PHAssetChangeRequest.deleteAssets(imageAssetToDelete)
        },
        completionHandler: { success, error in
            NSLog("Finished deleting asset. %@", (success ? "Success" : error))
    })
    self.dismissViewControllerAnimated(true, completion: nil)
    refreshCollectionView()
}
