The bug is in your code. It has always been a requirement that you nil out any delegate and datasource backpointers before the thing they point to gets deallocated. You just happened to get away with it due to some aspect of older Xcode versions’ codegen. This was a large motivation behind Zeroing Weak References (aka __weak in ARC). --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
