Not updated for Swift 5. Is this no longer supported?

The issue may be my own lack of knowledge. When I download the source code it compiles with no problem using Xcode 10.2.1 (Swift 5). But when I install the framework using CocoaPods, I get a handful of errors that need updating for Swift 5, but I cannot save the changes. I'd prefer to use the framework but it appears my only path forward is to integrate the source code into my project...?

I installed the pod using the instructions here: https://cocoapods.org/pods/CollapsibleTableSectionViewController
