I'm pretty new here and I'm still trying to figure out the nuances of swift, so please bear with me.
So I'm well aware that a Class cannot subclass more than once class, so how would I go about subclassing a cocoapod SwipeTableViewController as well as CollapsableTableViewController if I'm already subclassing UIViewController?
My second question is, why is the keyboard not presenting itself when I click on the textfield to name my workout? I tried using the textField.becomeFirstResponder(), but that didn't do anything for me. Any suggestions? I also have a pickerview in the same view as the textfield, could that have something to do with my issue?
Any help would be much appreciated!

For your first question, I don't think you need to worry.
You should inherit from CollapsibleTableSectionViewController if that is what you want to use. That itself extends UIViewController so you don't need to do it yourself.
I can't see any SwipeTableViewController in the SwipeCellKit - you just need to implement the delegate somewhere (in your main view controller code is fine) and you can 'inherit from' (actually, 'implement') this as it is a protocol, not a class (look into the difference between classes and protocols to find out why).
I can't see the relevant source code for your second question, but maybe that needs a separate question anyway.
