应用程序启动未返回有效的 pid，也未返回启动错误

Question

我的应用程序在模拟器上安装得很好，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抛出下面的错误。

我已经尝试了我所知道的所有技巧（删除派生数据并重新编译，到处注释掉一些代码，彻底搜索关键字）。

任何帮助或见解将不胜感激。

Answer 1

面临同样的问题。问题是模拟器是在 Xcode 之前启动的。

解决方案：只需关闭模拟器并重新构建项目即可

Answer 2

好吧，事实证明这个神秘的无名环境变量在方案中被检查了。我取消选中它并且它起作用了。

Answer 3

就我而言，即使我没有在 Rosetta 下运行它，我也必须安装它。为此，请运行此脚本：

softwareupdate --install-rosetta

或者如果您想跳过许可协议，请执行以下操作：

/usr/sbin/softwareupdate --install-rosetta --agree-to-license

Answer 4

造成此错误的原因似乎有多种。我在 M1 Max / macOS Monterey 上运行。我尝试了上面的一些解决方案，但发现它们要么不适用，要么没有效果。最后，答案（对于我的配置）就在这里——安装 Rosetta。这也是 Xcode 在每次启动时提示我做的事情。我正在运行一个使用 Cocapods 的应用程序。

Answer 5

对我来说，解决方案是将 Mach-O 类型更改为捆绑，然后再次运行应用程序（相同的错误）并将其再次更改回可执行文件。
