ユーザーからデータを収集してWebサービスに送信しようとしていますが、「JSON書き込みでトップレベルの型が無効です」というエラーが表示されます。関数を呼び出すと、すべてのデータがuserhealthprofile変数に正しく渡されます。しかし、何かが私のJSONコードに問題があるSwiftにユーザー入力JSONを投稿する
完全なエラーメッセージが、これは、これはUSERPROFILEのように見えるものである

のように(送信者ANYOBJECTが)あなたが取得しているエラーを追加... – Ladislav
完全エラーを追加しました –
userHealthProfileは '[[String:Any]]'または '[String:Any]'ではありません – Marcel
