在Xcode中构建项目时出错

Question

构建项目时出现以下错误。

Clening也没有帮助。 不知道突然出了什么问题

Answer 1

由于此错误表明您有重复的图像AppIcon和LaunchImage。 要对它进行排序，只需复制它并将其从项目中删除（查看Images.xcassets并将其删除）。 之后再将其导入Images.xcassets。

Answer 2

错误： AppIcon的多个实例（使用Storyboard时）。

这个解决方案对我有用：

在Storyboard窗口的Navigation面板中查找Images.xcassets的重复列表。 如果有，请突出显示并按删除键。 询问时，选择“删除引用” - 不发送到垃圾箱（可能会删除实际的Images.xcassets文件夹）。 显然，如果尝试中止将某些内容导入Images.xcassetes，则可能会出现项目中的重复列表。

Answer 3

对我来说，问题是我的资产文件夹有多个目标，而扩展已经分配了这些目标。 修复是为了确保每个资产文件夹仅分配给其特定目标，或删除不需要的文件夹。
