How does one subclass an extension locked inside a Pod?

Question

I have Cocoapod library that offers its functionality via an extension like this:

extension ExposedLibraryClass
{
    class func setup () { ... }
}

I have some boilerplate code that goes into setup() for every app I do, but each app also needs some bespoke bits adding after that. The problem is that this being an extension, I cannot subclass it, and just wedging bespoke code at the end of the setup() function is a very nasty solution.

What would you suggest I do, please? Thank you.

You can write as many extensions for a type as you like. But you cannot override methods in an extension. — Martin R, Feb 23 '16 at 16:12
extensions are _not_ for overriding methods of the original class – as its name says, they are _extensions_ only. — holex, Feb 23 '16 at 16:12

Nope, extensions can not override methods defined in another extension. They are for adding new functionality to existing objects.

The only way to do what you want would be to create a subclass of SomeClass and override the methods you want.

Take a look at the documentation on extension for the list of what they can do.
