为什么我的 M1 Mac 上的 Xcode 尝试构建“iOS Simulator-x86_64”？为什么它不为基于“arm”的模拟器构建？

Question

我有一台 M1 MacBook Air。

在 Xcode 中构建模拟器时，我看到以下警告和错误：

ld: warning: ignoring file /Users/kon/Library/Developer/Xcode/DerivedData/InvisibleComputersApp-hktlnhvaoskvxkcdhnahydmbodzw/Build/Products/Debug-iphonesimulator/GoogleSignIn.o, building for iOS Simulator-x86_64 but attempting to link with file built for unknown-arm64

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

在我看来，Xcode 正在尝试构建 x86 二进制文件？为什么它甚至试图这样做，模拟器不是arm基于 M1 Mac 的吗？

我怎么能够

Answer 1

我在这个问题上折腾了三天。今天终于破解了，明白了问题所在。

我正在开发一个包含约 100 个框架的高度模块化项目。从 X86_64 (Intel) 架构迁移到 arm64 (M1) 时，我总是收到此错误：

Could not find module 'MyModule' for target 'x86_64-apple-ios-simulator'; found: arm64-apple-ios-simulator, at /my/path/

在 M1 上本地构建时。

原因是模拟器在 M1 上本机运行，但模拟的应用程序仍在 Intel 下运行。这就是为什么首先构建 x86_64 架构的原因。

这两种架构现在正在互相竞争，因为模拟器是arm64，而模拟应用程序是X86_64。删除 pod 和项目设置的 arm64 架构解决了这个问题，我现在可以完全在 M1 上构建项目。

以下是 ActivityMonitor 的屏幕截图。AchieveMe 是在模拟器中运行的应用程序。

要解决 Cocoapods 的问题，您可以简单地执行以下操作：

Could not find module 'MyModule' for target 'x86_64-apple-ios-simulator'; found: arm64-apple-ios-simulator, at /my/path/

我正在使用 XcodeGen，可以简单地将其添加到调试配置下，如下所示：

target.build_configurations.each do |config|
  config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'arm64'
end

祝你好运，我希望它有帮助。我现在可以安心睡觉了。

您可以尝试打开 Xcode，并勾选“使用 Rosetta 打开”。

0. 退出 Xcode
1. 转到您的应用程序文件夹
2. 右键单击 Xcode，然后选择“获取信息”
3. 选中“使用 Rosetta 打开”
4. 打开Xcode
