XCode 11 添加 iOS 14 設備支持后崩潰

Question

我的 XCode 版本是 11.1，iPhone OS 版本是 14.0.1。 要在 iOS 14 設備上運行應用程序，需要 XCode 12。

在 XCode 11 中支持 iOS 14 的替代選項是添加設備支持。 所以我通過以下方式添加了對 iOS 14 的設備支持 -

轉到應用程序 > Xcode > 右鍵單擊 > 顯示 Package 內容 > 內容 > 開發人員 > 平台 > iPhoneOS.platform > DeviceSupport

然后在此目錄中添加設備支持文件。

設備支持文件可在此處獲得 - https://github.com/filsv/iPhoneOSDeviceSupport

添加設備支持后，每當我嘗試在 iPhone 設備上運行它時，它會立即顯示“構建成功”消息，然后 XCode 崩潰。

這是構建錯誤日志 -

There has been a security enhancement that stops Xcode 11 working with iOS 14 (the probable underlying reason causing the crash) but there is a workaround (and lots of other helpful information) at https://betterprogramming.pub/debugging-on-ios -14-with-xcode-11-d332f12f49dd解釋了如何啟動、記錄和調試。
