Sorry, I said NSProgress but I meant NSPredicate.

Re: [swift-corelibs-dev] KVC dependent classes
Hi David, It’s likely that we’ll have to come up with some alternative API in these cases. For example, in NSProgress I could imagine a callback for progress updates instead of observing the properties. It’s not ideal but I don’t think we want to undertake a reinvention of KVO when we do not have the Objective-C runtime present (so much of it relies on that dynamic behavior). - Tony > On Mar 14, 2016, at 4:14 PM, David Hart via swift-corelibs-dev >wrote: > > I was looking through Foundation for stuff to do and saw NSProgress, > NSExpression and NSSortDescriptor.

[swift-corelibs-dev] KVC dependent classes
I was looking through Foundation for stuff to do and saw NSProgress, NSExpression and NSSortDescriptor. They seem to be most reliant on KVC, and as KVC is not available without the Objective-C runtime, I’m not sure what those classes are doing here. Are those classes doomed to be dropped? Or is there another way to implement them? David. ___ swift-corelibs-dev mailing list swift-corelibs-dev@swift.org https://lists.swift.org/mailman/listinfo/swift-corelibs-dev
