推荐答案

词典是土生土长的斯威夫特结构。的NSDictionary是一类可可。它们都将通过桥彼此（通常的范围内），作为文档解释得很清楚，并充分。

Dictionary is a native Swift struct. NSDictionary is a Cocoa class. They are bridged to one another (within the usual limits), as the docs explain very clearly and fully.

它完全平行阵列和NSArray的。

It's exactly parallel to Array and NSArray.
