修复步骤 #

• 在iOS项目根目录新建任意名称的空Swift文件（如Placeholder.swift），弹出是否创建桥接文件的提示时选择是，无需修改新建文件的内容。该操作会强制XCode编译时引入Swift标准库，解决Swift依赖库自动链接失败问题。
• 将iOS项目的iOS Deployment Target设置为14.0及以上版本，BlueConic SDK依赖的swift_Concurrency等框架仅支持iOS14及更高版本的系统。
• 若使用XCode15及以上版本，在Build Settings的Other Linker Flags配置项中添加-ld64标记，避免新链接器导致的符号解析异常。
• 清理XCode缓存，重新执行pod install后编译即可。
