在 swift 中使用 `NSDictionary` 时出错

Question

我是 swift 的新手，我正在尝试在集合视图中显示图像集合

我收到此代码的错误

let asset: PHAsset = self.photoAsset[indexPath.item] as PHAsset
        PHImageManager.defaultManager().requestImageForAsset(asset, targetSize: PHImageManagerMaximumSize, contentMode: .ScaleAspectFill, options: nil, resultHandler: {
            (result: UIImage!, info: NSDictionary!)in cell.setThumbnailImage(result)

        })

'[NSObject : AnyObject]' is not identical to 'NSDictionary' 是错误，我不知道如何解决？

帮助说

func requestImageForAsset(_ asset: PHAsset!,
           targetSize targetSize: CGSize,
          contentMode contentMode: PHImageContentMode,
              options options: PHImageRequestOptions!,
        resultHandler resultHandler: ((UIImage!,
            [NSObject : AnyObject]!) -> Void)!) -> PHImageRequestID

你提供

info: NSDictionary!

更改它以便您提供

info: [NSObject : AnyObject]!
