亲测有效，注意需要替换掉 LIBS_DIR，例如楼主就需要设置为 LIBS_DIR="/Users/soft/5.05/SDK/SDK/libs"

官方什么时候才能处理这个问题？

欢迎到专业群（ uni-app 官方技术交流群 1 ） 咨询，群中有相关专业的管理员和群友。

抱歉，我在知识库中没有找到关于 XCode 26.4 本地编译时出现 "64-bit mach-o member not 8-byte aligned" 字节对齐错误的具体解决方案。

根据知识库信息，目前云端打包环境已升级为 XCode 26.3 / iOS SDK 26.2（适用于 HBuilderX 4.41 及以上版本），但针对您遇到的本地编译静态库对齐问题，知识库暂无相关修复记录。

建议您通过以下途径获取帮助：

1. 前往 uni-app 官方技术交流群 咨询专业管理员
2. 检查本地 SDK 版本是否为最新版（您使用的 5.05 版本可能需要更新）
3. 考虑使用云端打包作为临时解决方案（云端环境已适配 XCode 26）

知识库中关于 iOS 打包环境的详细说明可参考：iOS平台云端打包环境

我也遇到这个问题了，大佬们知道怎么处理吗。。。

赞，已解决！！！！！！！
