Xamarin.iOSアプリがiOS13の起動時にクラッシュする
数週間前、ユーザーがiOS 13ベータ版にアップデートした後、起動時にアプリがクラッシュするというフィードバックをユーザーから受け取り始めました。古いiOSバージョンでは同様の問題は発生していません。以前のバージョンは2019年4月に入手可能な最新のSDKでビルドされました。今、VS for Mac 8.2.6（ビルド73）にアップグレードし、Xcode 11プレビューチャネル、Xcode 11 GM 2でアプリを再構築しました。私がテストしたすべてのiOS 13シミュレータ（リリースビルドも含む）でアプリは正常に動作しますが、TestFlightユーザーはまだアプリが起動時にクラッシュすると言います。iOS13ベータ版への更新が失敗したため、自分のiPhoneデバイスでこれをテストできません。調査しましたあるユーザーから受け取ったクラッシュログですが、クラッシュの理由を見つけることができませんでした。

クラッシュが発生する現在知られているデバイス：iPhone 7、iPhoneX。分析データに基づくと、すべてのiOS 13デバイスにこの問題があるわけではありません（正確なデバイスモデルは不明です）。
下の画像は、「検索表示コントローラー」を示しています。私はこれを使用していませんでしたが（かなり古かったため）、iOS 13（実稼働ビルドのみ）で問題が発生しました。これが他の人の役に立つことを願っています。
単純に削除（または再コーディング）し、プロダクションビルドが機能するようになりました。
