应用程序启动没有返回有效的 pid 也没有启动错误答案

【问题标题】：Application launch did not return a valid pid nor a launch error应用程序启动没有返回有效的 pid 也没有启动错误
【发布时间】：2021-12-29 19:50:12
【问题描述】：

我的应用在模拟器上安装良好，我可以在手动打开它后附加该进程，但它不会从调试播放按钮运行而不会引发以下错误。

我已经尝试了所有我知道的技巧（删除派生数据并重新编译，在这里和那里注释掉一些代码，穷举搜索关键字）。

任何帮助或见解将不胜感激。

【问题讨论】：

我遇到了同样的错误。只需重新启动模拟器即可解决。
我有同样的错误，提供的两种解决方案都不适合我。

标签： ios swift xcode swiftui simulator

【解决方案1】：

好吧，原来这个神秘的无名环境变量已在方案中检查。我取消选中它并且它有效。

【解决方案2】：

对我来说，解决方案是将 Mach-O 类型更改为 bundle，然后再次运行应用程序（同样的错误）并将其再次更改回 Executable。

【讨论】：

对我不起作用:(

【解决方案3】：

就我而言，我试图运行单元测试，但在模拟器上使用午餐应用程序后出现了类似的错误。

对我有用的是我在构建单元测试目标时没有注意到编译器错误。修复测试目标构建问题后，应用程序再次正常运行。因此，请确保项目正在构建且没有任何错误。

【讨论】：

是的，即使测试目标显示构建成功，也存在编译器错误“问题导航器”。
