I’m putting together a tiny demo project which subclasses NSDocument. It has two targets, identical Cocoa macOS apps except one is in Objective-C and the other in Swift. In the Objective-C target, I override -[NSDocument willPresentError:] like this:
- (NSError*)willPresentError:(NSError *)error { NSLog(“Presenting!!”) ... ... } and that override is called prior to the display of an error dialog sheet, as expected. In the Swift target, with this code: override func willPresentError(_ error: Error) -> Error { Swift.print("Presenting!") ... ... } running the Swift app in the exact same way, presenting the same error dialog, this override is never called. It does not log “Presenting!”, and a breakpoint in there never breaks. A different print(), in deinit(), logs as expected. Is my syntax correct? I’m using Xcode 9.0, Swift 4.0.
