JSON in Swift / Error: Type 'Any' has no subscript members

Question

I have a JSON file which looks like this: here is a screenshot of my JSON file

and I my code is like this:

guard let data = data else {
    completionHandler(.failure(.missingResponseData))
    return
}
guard let json = try? JSONSerialization.jsonObject(with: data, options: []),
    let results = json["results"] as? [[String: Any]] else {
        completionHandler(.failure(.invalidJson(message: "data does not contain an array of objects")))
        return
}
do {
    let movies = try results.map {
        try Movie(json: $0)
    }
    completionHandler(.success(movies))
} catch let error as Error {
    completionHandler(.failure(error))
} catch {
    completionHandler(.failure(.other(error)))
}

but I get this error:

Type 'Any' has no subscript members

Any idea what I'm doing wrong?
