我有一些我已经创建的自定义控件，我正在新项目中使用它们.但是，我在接口构建器中不断收到错误:
Failed to update auto layout status: Failed to load designables from path (null)
或
Failed to render instance of <control>: Failed to load designables from path (null)
I've tested out the controls in another project and they seem to render c或rectly in interface builder, but I cannot get them to w或k in the current project. What causes this err或 and how might I fix it?
提前谢谢...
