Hello list,
I’ve encountered a bug for the life of me I can’t work out. I’m restricted to
supporting Mojave (10.14) for the time being, so it is possible this has been
fixed / not an issue on later releases. This is a Core Data backed application,
with several Xib loaded views that are swapped

Where’s the best place to intercept undo/redo actions to edit the action name

particular, when a particular entity’s attribute's change. Obviously, I want to

Hello Cocoa List,
I’m in the process of porting a hobby project to up-to-date Swift so it can be
used on Catalina (and I can upgrade my work machine - still looking for a
QuickTime 7 Pro replacement, though). I’ve encountered a phenomenon

Hello list,
Anyone know if it is intentionally the case that NSTableView doesn’t call
dragImageForRows(with dragRows: IndexSet, tableColumns: [NSTableColumn], event
dragEvent: NSEvent, offset dragImageOffset: NSPointPointer) -> NSImage
if you implement
func tableView(NSTableView,
Hello list,
After putting it off for too long, I’m migrating to view-based NSTableViews.
I’ve worked through most of the conversion problems I’ve had, and am generally
pretty happy. There is, however, one problem I haven’t been able to solve.
I have a NSButton in the same window as my table.

I have googled extensively on this issue, and it seemed pretty easy. The

Thank you both for responding. I am pretty sure I have everything linked up
properly. I first noticed a problem when I couldn't get a NSMenuItem to

subclass to test this:

Thanks again.
