Are there any other options?
It looks like an unintentional error in the 10.13 SDK. If you look at other “enforcement” types, such as Notification.Name, they’ve been given a backwards-compatible availability, since they are value-compatible. (They have to be, because the Cocoa methods haven’t changed.) I don’t see any immediate solution within Swift syntax. The only solution I can think of is to use an Obj-C “bridge", where you implement the override method in Obj-C, and have the override call a Swift method that doesn’t use the MaskMode type. (The old numeric masks are still available in the 10.13 SDK as deprecated global constants.) Unfortunately, this is a bit messy to do. The cleanest way I can think of is to create a NSObject subclass (in Obj-C) that has the override and a dummy Swift-compatible replacement method that the override calls. Your class would then subclass this, and override the dummy method. Make sure you submit a bug report. If the availability is intentional, then they need at least to be able to tell you how to write the override with backward compatibility. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
