このCoreDataエラーが発生します。このエラーが発生する理由はわかりません。Transformable型は使用していません。変換可能なプロパティを使用していることを示すコードが何も表示されません。プロジェクトの作成時に[コアデータを使用]オプションを選択して、XcodeにCoreDataをセットアップさせました。他の同様の質問は役に立ちません。答えは、プロジェクトの作成時にXcodeが作成されたことがわかるようなコードに関係しているためです。このエラーがデバッグウィンドウに表示されても、プロジェクトはクラッシュしません。Xcode 11.3とiOS用のGoogle Maps SDK for iOS 12を使用していますが、iOS 13.3を搭載したiPhone 8デバイスで実行されています。

Please switch to using "NSSecureUnarchiveFromData" or a subclass of NSSecureUnarchiveFromDataTransformer instead. At some point, Core Data will default to using "NSSecureUnarchiveFromData" when nil is specified, and transformable properties containing classes that do not support NSSecureCoding will become unreadable.
