前提

APIの結果を扱うアプリを作っています。

実現したいこと

Dictionary<String, Any>.Elementの中にある

試したこと

1日色々試してみましてがどれもダメでした。
①試したこと： if let ... で値にアクセスしてみる →✖️
https://qiita.com/Atsushi_/items/0dfe56878b269f805c2a

②Keyを探してValueを取得する →✖️
https://qiita.com/Saayaman/items/e82a09f93bb91409e446

③JSONDecoderを使ってDictionary→JSONへ変換
https://stackoverflow.com/questions/68060692/swift-dictionary-api-no-value-associated-with-key-codingkeysstringvalue-typ

JSONへの変換や文字列等の変換を試みてみましたが理解が浅く実現できませんでした。

補足情報（FW/ツールのバージョンなど）

Dictionary<String, Any>.Element自体あまりよくわかっていないのでお手柔らかにお願いいたします。

TwifterClientについて私はよく知らないのですが、こちらについてもどのようなものか質問欄に記載しておいた方が回答がつきやすいかもしれませんね。オブジェクトの形になっているvalueが全部Anyだとすると valueを取得するごとに[String: Any]にキャストする感じでアクセスできそうですがいかがでしょうか。 ```swift let statuses = results["statuses"] as? NSArray let status = statuses?[0] as? [String: Any] let user = status?["user"] as? [String: Any] print(user?["contributors_enabled"]) // Optional(0) ```

無事解決しました。

Swift
1let statuses = results["statuses"] as? NSArray
2let status = statuses?[0] as? [String: Any]
3let user = status?["user"] as? [String: Any]
4print(user?["screen_name"]) // Optional(TwitterJP)
