I don't even know how to describe the question! But the essence of sorting an array or replacing it with a non-array???

Question

iOS

the essence is that there is an array of the names of the posts, and there is an array of the IDs of these posts and they match in number and number in the array.
When a person clicks on a cell, he goes to the post. BUT!!!! Implemented word search that filters the array of post titles, but during filtering, the array of IDs no longer matches the array of filtered post titles.
HOW to filter them at the same time or can use not an array but a dictionary. In short, I don't even know what to do. Send!!!

Answer 1

In short, I implemented
self.dictWordId.updateValue(post["ID"] as! String, forKey: post["NAME"] as! String)
dictionaries and added the
following destanation.idPost = dictWordId[arFiltLet[(indexPath.row)] to segue ]!
