有人可以幫助我了解啟動時崩潰的問題：
當 iOS 在一段時間后預熱（這是新的 IOS 15 功能）應用程式并且用戶啟動應用程式時，它會崩潰。

uj5u.com熱心網友回復：
在 iOS 中有一個叫做 WatchDog 的應用程式。為了確保 iOS 不會崩潰或無回應，它會殺死所有回應時間過長的應用程式。
如果應用程式啟動時間過長，通常會發生這種情況。如果您在啟動應用程式時做的太多，這可能會發生。
它可以通過有趣的錯誤代碼來識別0x8BADF00D。大聲朗讀為“吃了不好的食物”??。
為了阻止這種情況，您需要減少在啟動應用程式期間正在執行的操作。有幾個 WWDC 討論如何做到這一點。加上幾個顯示使用方法的博客。
uj5u.com熱心網友回復：
我們有同樣的問題，但沒有崩潰。應用程式啟動（大約 30 分鐘后關閉），但在定位方面一切都呈現錯誤。
我們使用“場景”來實作 CarPlay 的“PointOfInterest”模板，如果我們排除“場景”（和 CarPlay），應用程式啟動就好了。
在 iOS 15 之前我們沒有這個問題，所以預熱可能是原因。
歡迎任何幫助。
