在XCode 12中找不到x86_64的符号-仅模拟器

如何解决在XCode 12中找不到x86_64的符号-仅模拟器

仅针对模拟器进行构建时，使用Xcode 12遇到以下错误。构建真正的iPhone效果很好。

请帮忙吗？

解决方法

升级到Xcode 12后，我在一个项目上遇到了同样的问题。解决该问题的原因是先运行pod deintegrate，然后运行pod install。

,

在我们的案例中，我们有一个项目，并将本机反应集成到其中。大约两周后（昨天），我开始遇到这种情况。因此，为了解决它……有点。我要做的是遵循本指南troubleshooting guide on react native's website并安装cocoapods-fix-react-native。按照说明将plugin 'cocoapods-fix-react-native'添加到您的PodFile中非常重要。

此后，我先运行pod deintegrate，然后运行pod install。

因此，现在当我使用Xcode进行构建时，所有的单词都会消失，但是如果我清理构建文件夹，则必须先执行pod deintegrate ，然后再进行pod install。

有时在构建时，Xcode会挂起，请停下来再重新构建。
