CoreNFC に関するすべてのドキュメントを読み、WWDC 2019 のタグの読み取りと書き込みに関するすべてのビデオを見ましたが、私の問題に関する情報は見つかりませんでした。オフィスの開いているドア/窓のデータをタグに書き込む必要があります。NFCタグを読み取ってswiftで簡単なプロジェクトを作成しますが、電話をUSBリーダーにかざすと、ログに次の問題が発生します:

私は decodeObjectForKey: class "NFFieldNotification" について何かを見つけようとしましたが、実際には Google ページに関する情報はありません。多分誰かが私を助けることができますか？それとも、iOS 13 ベータ 2 または xCode 11 ベータ 2 は生の製品なのでしょうか? この質問が将来役立つとしましょう...
