Googling for this suggests the problem is old, and not confined to Xcode 7b4, but the proposed solutions (deleting and re-typing the methods) doesn't work for me. Has anyone found a better solution?
I have a simple NSOutlineView in source list mode, using an NSOutlineViewDataSource, in Swift 2. I've implemented …numberOfChildrenOfItem:, …child:ofItem:, …isItemExpandable:, and …viewForTableColumn:item:. I've even tried adding …objectValueForTableColumn:byItem:, which docs say is not necessary for view-based views. But I still get this at run time: *** Illegal NSOutlineView data source (<NSViewController: 0x6080000c6740>). Must implement outlineView:numberOfChildrenOfItem:, outlineView:isItemExpandable:, outlineView:child:ofItem: and outlineView:objectValueForTableColumn:byItem: I'm not sure why those methods are optional if they must be implemented, but whatever. Any suggestions on how to get it to behave?
