推荐答案

项目设置>在目标下，选择你的项目>构建阶段>
打开编译源代码和复制捆绑资源。检查是否有任何文件以红色列出。如果是这样，只需删除它。然后清洁并运行。

Project Settings > Under "Targets", select your project > Build Phases > open "Compile Sources" and "Copy Bundle Resources". Check if any files are listed in red color. If so , just delete it. Then clean and run.

为我工作。
