私は、睡眠分析に関する以下のスウィフトスクリプトを持っています。スイフト：未解決の識別子の使用。対象メンバーシップ
エラー：
View Controller has no member 'updateTime'.
私は、ファイルインスペクタを使用して、このターゲットを追加し、会員を対象とし、それを追加しようとしたが、ターゲット自体が奇妙を超えており、表示されません。どんなフィードバックも高く評価されます。
PS：「エラー」はif != nilステートメントの未解決の識別子ではないという別のエラーメッセージがポップアップし続けます。ここのお手伝いも高く評価されます。

であなたのコードを置き換えあなたには、いくつかのインデントと可能な範囲の問題がある可能性がありますように見えます。関数updateTimeがクラスで定義されていることは確かですか？ – ryantxr
