我的要求：我将在表视图中显示聊天详细信息列表。在表视图顶部，将使用文本字段进行搜索。基于用户的唯一ID，应完成搜索。不是用户输入的具有唯一ID的聊天，那么它必须重定向到另一个称为chatcreatepage的屏幕。每当我们搜索聊天时，我们都会使用一个名为FIND API的API，并且在该FIND API中有一个聊天字典，如果为null，则将调用create chat。如果该聊天字典不为nil，则需要显示聊天列表视图中的聊天详细信息。当加载聊天列表页面时，我们将调用聊天列表Api。当我们通过在文本字段中输入唯一ID进行搜索时，我们将获取输入的唯一ID和我们拥有的唯一ID详细信息在表格视图中显示。
这是我的任务，直到表格中显示聊天列表为止。我真的不知道在调用FIND API之后显示的搜索结果，如果有人帮助我解决它，那真的很棒。提前。我在下面提供代码。

您必须使用UISearchBar并在searchbar func searchBar（_ searchBar：UISearchBar，textDidChange searchText：String）的委托方法中调用api。 供参考，请使用此https://guides.codepath.com/ios/Search-Bar-Guide
