我是Xcode和Swift的新手，因此对任何幼稚的行为表示歉意。
我设法使用dropsource组合了一个应用程序，该应用程序连接了多个链接的tableViewControllers。现在，我想使用主页（第一个TableViewController）上的SearchBarController编写搜索栏，该搜索栏搜索应用程序中的所有表，并允许用户直接跳到任何表中的单元格（与搜索中的文本匹配）栏），然后点击它。
我的问题是我所有的表都使用API设置，但我不确定如何将数据从API连接到搜索栏。将字符串变量连接到搜索栏很简单，但是事实证明，连接API太多了。
我可以使搜索栏完美地显示在页面上，但不能将其与任何数据链接。
我特别努力的是在updateSearchResults函数中放置什么表达式来访问不同表的API /数据：
func updateSearchResults(for searchController: UISearchController) {
//what expression should I write here to allow the search bar to access multiple API's/tableViews
//what expression do i follow up with here to output all the cells from all the tables that match the search term into one table
}
这是主页上我的代码提供上下文的全部内容：
