无需Rosetta修复CircleCI Apple Silicon iOS测试启动失败问题

我有一个原生iOS应用，使用CircleCI的Apple Silicon节点进行CI/CD。当不启用Rosetta时，运行模拟器单元测试会触发**"Failed to install or launch the test runner"**错误。以下是我的配置文件及错误日志，求不依赖Rosetta的解决方案。

config.yml配置 #

version: 2.1

# setup: true

orbs:
  macos: circleci/macos@2.4.1
  ruby: circleci/ruby@2.1.2

parameters:
  application-nonprod-context:

    default: application-nonprod-context-default-value

executors:
  my-executor:
    macos:
      xcode: "15.3.0"
      resource_class: macos.m1.large.gen1

    steps:

          command: bundle exec fastlane tests

错误日志 #

Testing failed:
        Simulator device failed to launch com.mycompany.myapp.debug.
        MyApp encountered an error (Failed to install or launch the test runner. (Underlying Error: Simulator device failed to launch com.mycompany.myapp.debug. No such process. (Underlying Error: Application launch for 'com.mycompany.myapp.debug' did not return a process handle nor launch error. No such process)))

1. 修正项目架构配置 #

• 打开Xcode进入项目Target的Build Settings：
  • 将Architectures设置为Standard Architectures (arm64)，移除x86_64架构
  • 确保Build Active Architecture Only在Debug模式下设为Yes
  • 若存在VALID_ARCHS配置，仅保留arm64

2. 调整CircleCI配置 #

• 删除config.yml中的- macos/install-rosetta步骤，完全禁用Rosetta
• 替换macos/preboot-simulator为手动启动命令，确保模拟器以arm64架构运行：

  - run:
      name: Boot arm64 simulator
      command: |
        xcrun simctl boot "iPhone 15 Pro (17.4)"
        xcrun simctl list devices | grep Booted
  

3. 更新Fastlane测试配置 #

• 在run_tests命令中添加destination参数，明确指定arm64架构：

  lane :tests do
    run_tests(
      workspace: "MyProject.xcworkspace",
      devices: ["iPhone 15 Pro (17.4)"],
      scheme: "UnitTests",
      clean: true,
      parallel_testing: false,
      configuration: "Debug",
      derived_data_path: ".Build",
      build_for_testing: true,
      destination: "platform=iOS Simulator,name=iPhone 15 Pro,OS=17.4,arch=arm64"
    )
  end
  

4. 添加缓存清理步骤 #

• 在CircleCI测试步骤前添加缓存清理，避免旧架构构建残留：

  - run:
      name: Clean simulator and derived data
      command: |
        xcrun simctl erase all
        rm -rf ~/Library/Developer/Xcode/DerivedData/*
  

5. 验证Xcode与模拟器兼容性 #

• 确认Xcode 15.3已正确安装iOS 17.4模拟器包，若存在兼容性问题，升级Xcode到最新稳定版本
