解决方案 #

1. 清理构建缓存 #

• 执行Flutter清理命令：

  flutter clean
  

• 进入iOS目录清理Pods及相关缓存：

  cd ios
  pod deintegrate
  pod clean
  rm -rf Podfile.lock .symlinks Flutter/Flutter.framework Flutter/Flutter.podspec
  

2. 重新安装依赖 #

• 返回项目根目录更新Flutter依赖：

  flutter pub get
  

• 回到iOS目录重新安装Pods：

  cd ios
  pod install --repo-update
  

3. 调整Xcode构建配置 #

• 打开iOS目录下的Runner.xcworkspace
• 进入Runner target的Build Settings：
  • 确认Valid Architectures设置为arm64 x86_64（适配模拟器架构）
  • 检查PhaseScriptExecution脚本路径，确保Flutter相关脚本路径正确

4. 修复Xcode插件缓存问题 #

针对日志中IDEWatchSupportCore插件报错，执行以下操作：

rm -rf ~/Library/Application\ Support/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments/com.apple.dt.xcode.sfl2
rm -rf ~/Library/Caches/com.apple.dt.Xcode
rm -rf ~/Library/Developer/Xcode/DerivedData

完成后重启Xcode和开发IDE（Android Studio/VS Code）

5. 验证版本兼容性 #

• 检查当前Flutter版本：

  flutter --version
  

• 确保Flutter版本与Xcode版本兼容，若不匹配，可升级Flutter：

  flutter upgrade
  

  或降级Xcode至兼容版本
