Xcode单元测试报错：找不到arm64-apple-ios-simulator模块

问题定位 #

报错Could not find module 'MyApp' for target 'arm64-apple-ios-simulator'; found: x86_64-apple-ios-simulator本质是主应用、测试目标与Pods的编译架构不统一——Apple Silicon芯片的模拟器需要arm64架构，但现有配置导致各模块编译出的架构不一致。

修复步骤 #

1. 统一主应用与测试目标的架构配置 #

打开Xcode，依次检查主App Target和测试Target的Build Settings：

• 找到Excluded Architectures：清空所有针对iphonesimulator的手动配置，让Xcode自动适配当前设备架构
• 找到Build Active Architecture Only：Debug模式设置为YES，Release模式设置为NO
• 确保两个Target的上述配置完全一致

2. 调整Pods的编译配置 #

修改Podfile中的post_install脚本，替换原有架构相关配置，确保适配Apple Silicon模拟器：

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '5.0'
      config.build_settings['ENABLE_BITCODE'] = 'NO'
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
      config.build_settings['APPLICATION_EXTENSION_API_ONLY'] = 'NO'
      
      # 根据模式设置仅编译活跃架构
      config.build_settings['ONLY_ACTIVE_ARCH'] = config.name == 'Debug' ? 'YES' : 'NO'
      # 移除硬编码的arm64排除规则，交由Xcode自动处理
      config.build_settings.delete('EXCLUDED_ARCHS[sdk=iphonesimulator*]')
      
      config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
      config.build_settings['CODE_SIGNING_ALLOWED'] = 'NO'
      config.build_settings['DEVELOPMENT_TEAM'] = '62365DL5L2'
      config.build_settings['CLANG_WARN_STRICT_PROTOTYPES'] = 'NO'
    end
  end
end

3. 清理缓存并重新构建 #

• 在终端执行：pod deintegrate && pod install
• 回到Xcode，按Cmd+Shift+K清理构建缓存，再按Cmd+B编译主应用，最后运行单元测试

4. 验证测试目标依赖 #

检查测试Target的Build Phases：

• 确认Target Dependencies中包含主App Target
• 确认Link Binary With Libraries中正确引入了主App的框架
