iOS模拟器安装WidgetKit应用报错SendProcessControlEvent:toPid: Error Code8求助

我尝试在iOS模拟器上安装一款WidgetKit应用，但遇到了无法解决的错误：应用启动失败，小组件也未在模拟器中显示。收到的错误日志如下：

系统环境 #

• macOS Version 14.5 (Build 23F79)
• Xcode 15.2 (22503) (Build 15C500b)
• 时间戳：2024-08-17T11:01:48+05:00

可能的解决方法 #

• 校验Bundle ID拼写：错误日志中的com.mlbench.MyWedgetApp.DateWedget存在拼写错误（Wedget应为Widget），检查项目中小组件目标的Bundle ID是否存在同样拼写错误，修正后重新构建。
• 清理构建缓存：
  1. 使用Cmd+Shift+K清理项目
  2. 使用Cmd+Option+Shift+K清理构建文件夹
  3. 重启Xcode和模拟器后重新运行项目
• 重置模拟器：打开模拟器，选择Device → Erase All Content and Settings，重置完成后重新安装应用
• 检查小组件配置：
  • 确认小组件目标的Info.plist中，NSExtension下的NSExtensionPointIdentifier值为com.apple.widgetkit-extension
  • 确保主应用与小组件目标使用相同的签名配置（开发团队、证书一致）
• 更新开发工具：尝试升级Xcode至最新版本，或更新macOS系统，修复已知的兼容性问题
