This project seems abandoned. What are the alternatives?

No updates in two years. Anyone knows any active forks of RATreeview? Or willing to take over and pull merge requests?

Quick search on cocoacontrols got me these, but none of them are mature enough and maintained, except maybe first two:

• https://github.com/KiranJasvanee/InfinityExpandableTableTree
• https://github.com/gringoireDM/LNZTreeView
• https://github.com/cenksk/CITreeView
• https://github.com/partho-maple/PBTreeView
• https://github.com/ujell/YUTableView

This one seems to be regular updated. But it's all in Chinese.

I use SwiftListTreeDataSource to visualise hierarchical data structures (trees) in lists-like way. It's UI agnostic, just like view-model, so you can use it with UITableView/UICollectionView/NSTableView or even SwiftUI with search support.
