推荐答案

项目设置 > 在目标"下，选择您的项目 > 构建阶段 >打开编译源"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，只需将其删除.然后清理并运行.

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.
