Xcode 构建失败未显示相关错误消息

Question

我试图在 iOS 上从 Flutter 构建一个应用程序，但是当我尝试运行构建时，我收到以下错误：初始化失败后无效重用。这就是我在错误消息方面得到的全部信息。我尝试在网上查找，但没有找到任何相关内容。我想我的 info.plist 可能有问题，但我找不到任何错误。下面是 info.plist 的内容

Answer 1

清理构建文件夹 ( Cmd+Shift+K) 帮助我解决了初始化失败后的无效重用问题

Answer 2

刚刚遇到了同样的问题。我通过双击文件概述中的 Runner 修复了它。这在右侧显示了身份和类型。如果您将项目格式（在项目文档下）设置为 Xcode 12.0-compatible，它就可以工作。

希望描述有帮助。我只在为 iOS 测试 Flutter 构建时使用 mac，所以我不是专家：p
