多次元配列を作成し、各セクションの下に各配列を表示しようとしていますが、致命的なエラーインデックスが範囲外になってしまいます。私の下に表示されているコードは、firebaseデータにアクセスしてデータベースから各配列を印刷する方法です。問題は、配列を割り当てるためのデータを取得することですが、エラーのために表示できないようです。誰かが私がスクリーンショットを添付したエラーに関する参考になることを願っています。swiftの異なるセクションに多次元配列を表示する方法3

エラーは「インデックスが範囲外です」です。私はチェックしませんでしたが、 'days.count'！= coursenames.countなので、私は = coursenames.countです。 –
