Swift - how to get last taken 3 photos from photo library?

Question

I need to get and show last taken 3 photos from photo library on viewDidload event without any clicks.

After this step, I should get other photos 3 by 3

Here is @Lindsey Scott's answer but in Objective-C. I am putting the last 9 photos from Camera Roll into a collection view:

-(void)fetchPhotoFromEndAtIndex:(int)index{

PHImageRequestOptions *options = [[PHImageRequestOptions alloc]init];
options.synchronous = YES;
PHFetchOptions *fetchOptions = [[PHFetchOptions alloc]init];
fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:YES]];

PHFetchResult *photos = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];
if (photos) {
    [[PHImageManager defaultManager] requestImageForAsset:[photos objectAtIndex:photos.count -1 -index] targetSize:CGSizeMake(self.collectionView.frame.size.width/3, self.collectionView.frame.size.height/3) contentMode:PHImageContentModeAspectFill options:options resultHandler:^(UIImage *result, NSDictionary *info) {
        [self.imagesArray addObject:result];

        if (index + 1 < photos.count && self.imagesArray.count < 9) {
            [self fetchPhotoFromEndAtIndex:index + 1];
        }
    }];
}

[self.collectionView reloadData];

}
