Description

Lets Say I have a Swift class A I want to have tab bar like the one in your Youtube Example.

So I would be declaring it like

@objc class A: BaseButtonBarPagerTabStripViewController<MyCustomTabCell>

The reason I used @objc is because I will use my class in Objective C code. This will give a compile time error because Classes with Swift generics can not be used in Objective C.

please see this thread

Can you please tell me a workaround

Research direction
Investigate why Swift generic classes cannot be exposed to Objective C due to the absence of generic type information at runtime. Review the StackOverflow thread linked in the issue for potential workarounds such as creating a non generic base class or using type erasure. Consider adding documentation or an example in the repository showing how to wrap generic classes for Objective C compatibility.
