I was going to say "no", because my bug's still open, but in fact I never filed one. :( The following are still "open" (including their duped-to originals) though: 24046976 / 21380125 NSSplitView's delegate should be weak not assign 21366070 / 18987740 NSAnimation delegate should be 'weak' not 'assign' 17553217 NSSpeechRecognizer delegate should be 'weak' not 'assign' 17540574 NSToolbar's delegate should be 'weak' not 'assign' 17540533 NSWindow's delegate should be 'weak' not 'assign' 15301393 / 10520557 Support zeroing weak references (under ARC) with NSTextView As for NSMenu, it came back: "Although the delegate is declared “assign” in NSMenu.h, it’s actually been weak (for weak-compatible objects) since 10.9." When switching from GC to ARC, all this was a PITA. Cheers, -- ____________________________________________________________ Sean McBride, B.
