[swift-evolution] Smart KeyPaths

[Kenny Leung]

Hi All.

I’m not sure I’m understanding this proposal properly. In (old) Cocoa, two places where key paths were used extensively was EOF/CoreData, and WebObjects. I’m wondering how Smart KeyPaths will solve these two problems:

1. fetching data from a database and stuff it into objects that are not known at compile time (since you’ve written the framework ahead of time)

2. Token replacing text in a template, like ${person.firstName}

Will there be some conversion of key paths to/from strings?

Thanks!
