解决方案 #

报错原因是项目资源文件包含Finder信息或资源分支数据，iOS签名工具不允许这类文件存在，按以下步骤处理：

• 清理项目资源冗余数据
  打开终端进入项目根目录，执行命令删除所有文件的扩展属性：

  xattr -cr .
  

  该命令会递归清除当前目录下所有文件的Finder信息、资源分支等冗余数据。

• 清理Flutter与Xcode缓存

  1. 清除Flutter缓存：

     flutter clean
     

  2. 进入iOS目录，重置Pod依赖：

     cd ios
     pod deintegrate
     pod install
     cd ..
     

  3. 删除Xcode DerivedData目录：
     执行命令删除对应项目的DerivedData文件夹：

     rm -rf ~/Library/Developer/Xcode/DerivedData/Runner-fpfnxymfuwkswxabxobwfhbmujgy
     

• 重新构建项目
  执行Flutter构建命令：

  flutter run ios
  

  或直接在Xcode中选择目标设备点击运行按钮重新构建。

• 排查资源文件来源
  若问题反复出现，检查图片、音频等资源是否从Mac Finder直接复制（这类文件易携带Finder信息），建议重新从原始渠道获取资源，或复制后用xattr -cr命令处理。
