エンコード/デコードSwiftのCNContactオブジェクトを一般的な方法でJSONエンコード/デコードしようとしています（これは、オブジェクトが実行時に保持するプロパティを判別したいという意味で、そのプロパティをハードコードしたくない）しかし、私はそうすることはできませんでした。私の質問は、スウィフト4でこの行動を達成する方法はありますか？もしそうなら、どうすればいいのですか？Swift CNContactオブジェクトを一般的に
いいえ、official documentationに従ってCNContactは変更されていないため、Encodeable & DecodableのタイプアライメントであるCodableプロトコルに準拠していません。 EncodableとDecodableに現在準拠しているクラスのリストを見ることができます。CNContactもその中にはありません。
ただし、上記のプロトコルに準拠するようにCNContactの内線番号を書くことができます。
フレームワークを使用してCNContactオブジェクトをSwift3にエンコードする方法の例を次に示します。これは単なる例であり、可能なすべてのフィールドを解析しておらず、CNContactオブジェクトに特定の値が存在しない場合は、JSONにキーが存在しないことに注意してください。また、デコーダの機能は完全には実装されていませんが、エンコーダの動作を確認すれば簡単に実装できます。
JSONキーの名前も構造と一緒に任意に選択されていますので、それらを変更することができます。
以下のコードは、完全に動作するプレイグラウンドファイルです。必要に応じて、自分でテストすることができます。
