macos crashlyticsが報告を送信中にクラッシュする

Question

私の（最初の）macOSアプリに問題があります。ベータテスターは、アプリの開始時にクラッシュを取得します。 なぜ私は少し困惑しています。 私はcrashlyticsフレームワーク（バージョン3.9.3（128））を含めました。 crashlyticsが（以前のクラッシュからの）レポートを送ろうとしている間、クラッシュしているようです。

誰かに似たような経験がありますか？クラッシュレポートから

Answer 1

マイク。私はこれがCrashlyticsのクラッシュだとは思わない。ほとんどのクラッシュレポートで参照されるスレッドが表示されるのは、プロセスが目を覚まして例外を捕まえるためです。

表示されているエラーは、通常、メモリの管理ミスや存在しなくなったオブジェクトの保持によるものです。
