已尝试的解决步骤 #

• 更新iOS部署目标至15.0：
  • 修改Podfile设置platform :ios, '15.0'
  • 在Xcode项目设置中把iOS Deployment Target设为15.0
• 清理并重新安装依赖：
  • 执行flutter clean
  • 删除Pods和Podfile.lock
  • 执行pod install
• 验证依赖兼容性：
  • 检查所有依赖是否兼容Swift 5和iOS 15.0
• 修改Xcode构建设置：
  • 确保Swift Language Version设为5.0
  • 在Framework Search Paths和Other Linker Flags中添加$(inherited)

以上步骤均未解决问题，仍提示相同错误，寻求可行的解决建议。
