metro捆绑器不连接ios模拟器，但构建器显示模拟器

Question

我正在尝试为我的react native应用程序react-native run-ios运行iOS模拟器。它构建和metro捆绑器CLI运行，设备模拟器运行，但应用程序没有连接metro捆绑器。

我运行"react-native"; "0.66.0"xcode 13.0

我首先杀死所有模拟器。然后运行cmdreact-native run-ios

第一个窗口构建应用程序并启动窗口2

$ react-native run-ios

• iphone 13 pro max已打开并运行。但是我的应用程序没有运行
我看到我的应用程序图标。我试着运行它，但是它自动关闭了，窗口2显示"警告没有应用程序连接…"消息。

我试过却没有做任何事

• 删除node_modules并运行yarn install
• podfile删除。锁和pod文件夹。ranpod install
• 确保xcode>产品比;计划在构建配置>调试。不释放。
• rm -rf ~/Library/Developer/Xcode/DerivedData
• 卸载xcode, npm, yarn, src code并重启。

帮忙吗?

这就解决了。检查崩溃日志。~/Library/Logs/DiagnosticReports当直接从模拟器启动时，应用程序会崩溃但如果我在Xcode中通过play按钮在模拟器中启动应用程序它会正常运行
