Cocoapodsframework cannot be inherited when swift uses CocoaPods to import the third-party library's framework parent class to the subclass.

When I encountered such a problem in today's development project, I used cocoapods to import the third-party library to BaseController, And the other controllers inherited from basecontroller, however, classes that cannot be indexed to the third-party library in the inherited subclass can only call the category method of UIKit.

Subclass

Parent class

 

The current solution is to re-import the header file of the third-party library in the subclass.

PS: I have not studied why such a problem occurs. I hope you can tell me the reason when you see or know the principle.
