如何按修改日期对CloudKit结果进行排序？
[英]How do I sort CloudKit results by modified date?
问题描述
I'm trying to order search results by the modified date. 
我正在尝试在修改日期之前订购搜索结果。 If I wanted to do by creationDate its: 如果我想通过creationDate进行操作，请执行以下操作：
query.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
What's the key for modified date? 修改日期的关键是什么？ A list of all NSSortDescriptor keys or a way to find them would be extremely helpful. 所有NSSortDescriptor键的列表或找到它们的方法将非常有帮助。
