【问题描述】：

我只是想调试我在 ios 上的 Flutter 应用中所做的一些更改。从 VS Code 启动它并收到以下错误：

libc++abi: terminating with uncaught exception of type std::__1::system_error: thread constructor failed: Resource temporarily unavailable
* thread #1, queue = 'com.apple.main-thread', stop reason = signal SIGABRT
    frame #0: 0x00000001b928e964 libsystem_kernel.dylib`__pthread_kill + 8
libsystem_kernel.dylib`__pthread_kill:
->  0x1b928e964 <+8>:  b.lo   0x1b928e984               ; <+40>
    0x1b928e968 <+12>: pacibsp 
    0x1b928e96c <+16>: stp    x29, x30, [sp, #-0x10]!
    0x1b928e970 <+20>: mov    x29, sp
Target 0: (Runner) stopped.

据我了解以及在互联网上找到的内容，该应用程序无法创建线程。不幸的是，它并没有说明为什么会发生这种情况或谁在尝试创建线程。

我尝试了多种方法来减少引起的可能性：

使用过的模拟器 使用真实设备 flutter clean 重启 VS Code 重新启动 Mac 回滚我的代码更改 在设备上安装而不是调试

没有任何改变。错误仍然出现。没有机会在另一台 Mac 上运行它。

有人知道错误或有什么建议吗？

【参考方案1】：

通过检查 git 中的最新更改来解决它。反转文件Info.plist中的以下行后

    <key>UILaunchStoryboardName</key>
    <string>Main</string>

到

    <key>UILaunchStoryboardName</key>
    <string>LaunchScreen</string>

我仍然不明白为什么这会导致错误，但现在它消失了。
