How to get non nil in file path in subfolders in Main Bundle?

Question

iOS

Hey! There is a task to open browser games in WebView, which I copied into the project (see screenshot).
When I try to get the path of a file inside a folder, I always get path = nil:

let path = Bundle.main.path(forResource: "index", ofType: "html", inDirectory: "games/game1")

But if you put index.html in the root of the project, and use the method without the inDirectory parameter, then the path is found.

let path = Bundle.main.path(forResource: "index", ofType: "html")

Question: how to get the path to a file that is inside a folder?
PS I copied the folder to the project not as groups, but even if you copy it as groups (yellow folders), the result does not change.
