UIKit和AppKit中的可区分数据源是声明性的。
这意味着框架不会询问你有多少个部分，而是在准备NSDiffableDataSourceSnapshot时，你会告诉框架有多少个部分。
英文:
The diffable data sources in UIKit and AppKit are declarative.
This means the framework doesn't ask you for the number of sections, instead you tell the framework the number of sections while preparing the NSDiffableDataSourceSnapshot.
