Thread 1: "Diffable data source detected section identifiers that are equal but have different hash values. Two identifiers which compare as equal must return the same hash value.

Identifiers that are equal but have different hash values: (BilibiliLive.SearchList(title: "视频", width: <NSCollectionLayoutDimension: 0x283c4ff20>, height: <NSCollectionLayoutDimension: 0x283c4ff60>, scrollingBehavior: __C.UICollectionLayoutSectionOrthogonalScrollingBehavior)) and (BilibiliLive.SearchList(title: "视频", width: <NSCollectionLayoutDimension: 0x283c7ac60>, height: <NSCollectionLayoutDimension: 0x283c79420>, scrollingBehavior: __C.UICollectionLayoutSectionOrthogonalScrollingBehavior))"
