编辑 2020-05-06：我的应用程序从 iOS 13.4 正确安装，但一段时间后应用程序在启动时崩溃，我必须重新安装它。我不知道为什么。也许在iOS更新之后？

我正在尝试flutter create在 iOS 设备（iPhone XS）上运行一个新的 Flutter 应用程序（由 创建的示例应用程序）。Xcode 设法安装它，但随后崩溃并显示以下消息：
dyld: Library not loaded: @rpath/Flutter.framework/Flutter
Referenced from: /private/var/containers/Bundle/Application/BA807438-FA5B-4021-B37D-FC437B2C80CA/Runner.app/Runner
Reason: no suitable image found. Did find:
/private/var/containers/Bundle/Application/BA807438-FA5B-4021-B37D-FC437B2C80CA/Runner.app/Frameworks/Flutter.framework/Flutter: code signature invalid for '/private/var/containers/Bundle/Application/BA807438-FA5B-4021-B37D-FC437B2C80CA/Runner.app/Frameworks/Flutter.framework/Flutter'
如果我尝试flutter run，该应用程序也会打开并崩溃。并且命令永远等待：
