在Rosetta模式下使用Xcode 14.0。

\n

Rosetta模式下的Xcode 14.1 - 同样的问题

\n

没有 Rosetta 的相同配置也可以正常工作。（在我的产品项目中，由于第 3 方依赖，我必须使用 Rosetta）

\n

为活动架构构建设置为NO

\n

为 Active 架构构建不会YES改变任何内容

\n

所有常见的事情都尝试过：

\n

\n
• 重建项目
\n
• 干净的派生数据
\n
• ETC。

The answer to those who came here with the same problem: \n\nIf you have to run in **Rosetta** mode, keep checking this post.\n\nOtherwise, run without **Rosetta**, that will solve your problem.\n

我遇到了同样的问题。基于 M1Pro 构建，未安装 Rosetta。iOS 项目。预览工作正常，然后在我移动一些代码以适应所需的应用程序结构（不是我的）后的一天停止了。预览错误指示一个特定的 swift 源文件，但当我将其复制到另一个项目时，它完美地编译和预览。
