swift - 有没有办法了解导致 `_NSTouchBarFinderObservation` 崩溃的原因？

Question

My Crashlytics 显示多个用户遇到以下崩溃(见下文)。我能够重新创建它的唯一方法(我怀疑用户正在这样做)是调出 Xcode Touch Bar 模拟器并在应用程序运行时在 generations 之间切换:

以下设备和操作系统已报告崩溃:

• macOS 12.2.0 MacBookPro16,1
• macOS 12.2.0 MacBookPro15,4
• macOS 12.1.0 MacBookPro15,4
• macOS 12.0.0 MacBookPro15,4

我的应用是:

• 仅限 macOS
• 用 SwiftUI 编写，包含一个 NSViewController 和 NSTextView
• 永远不要触摸/观察/引用触摸栏。

谁知道这次崩溃的原因？

Cannot remove an observer <_NSTouchBarFinderObservation 0x6000026f6260> for the key path "nextResponder" from <GUL_SwiftUI.AppDelegate-0624A6E4-3CE4-4739-BDD0-0721CE556CBA 0x600000290360> because it is not registered as an observer.

原来罪魁祸首是 Firebase Analytics。防止此崩溃的解决方案是将 FirebaseAppDelegateProxyEnabled 添加到信息 plist 并为其指定 Boolean 值 NO。似乎 SwiftUI、macOS 和 Firebase Analytics 不能很好地协同工作。
