Read the Resource Programming Guide. -initWithCoder: is primarily called when unarchiving a view from a nib. It’s kind of annoying that Swift makes you implement this method for all views, regardless of whether they’ll be in a nib or not, but it’s the only way the language can back up its safety guarantees. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
