I put in a table-view for the top half of a OS X storyboard, and a tab-view for
the bottom. I couldn't figure out how to modify the tabs with more controls.
Eventually I followed web tutorial and replaced the tab-view with a custom view
that's attached to a tab-view controller, which itself has
OS X 10.11.5, Xcode Version 7.3.1 (7D1014).
App with TableView (View based). Works fine.
But when I give the TableView a delegate (even without implementing any
NSTableViewDelegate methods) it crashes (see below).
How to debug this?
Tried a symbolic breakpoint in -[__NSArrayM objectAtIndex:]
