CI/CD 自动化

问题

iOS 项目如何实现自动化构建和发布？

答案

Fastlane

# Fastfile
default_platform(:ios)

platform :ios do
  desc "运行测试"
  lane :test do
    run_tests(scheme: "MyApp")
  end

  desc "发布到 TestFlight"
  lane :beta do
    increment_build_number
    build_app(scheme: "MyApp")
    upload_to_testflight
  end

  desc "发布到 App Store"
  lane :release do
    build_app(scheme: "MyApp")
    upload_to_app_store(
      skip_metadata: true,
      skip_screenshots: true
    )
  end
end

GitHub Actions

name: iOS CI

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  build:
    runs-on: macos-latest
    steps:
      - uses: actions/checkout@v4

      - name: Select Xcode
        run: sudo xcode-select -s /Applications/Xcode_15.0.app

      - name: Install dependencies
        run: |
          xcodebuild -resolvePackageDependencies

      - name: Run tests
        run: |
          xcodebuild test \
            -scheme MyApp \
            -destination 'platform=iOS Simulator,name=iPhone 15' \
            -resultBundlePath TestResults

      - name: Build
        run: |
          xcodebuild build \
            -scheme MyApp \
            -configuration Release

常见面试问题

Q1: CI 上代码签名怎么处理？

答案：

1. Match（Fastlane 推荐）：证书和 Profile 存储在 Git 私有仓库，CI 上自动下载安装
2. 手动：将 .p12 和 .mobileprovision 作为 CI 机密变量，构建前安装到钥匙串
3. Xcode Cloud：Apple 原生 CI，自动处理签名
