There is no specific proposal for naming extensions because there is nothing gained by just giving them a name. However, named extensions have been discussed in the context of other features such as allowing extensions to have stored properties. This is discussed in the appendix of the partial initializer proposal I started but tabled until after Swift 3: https://github.com/anandabits/swift-evolution/blob/partial-initializers/proposals/NNNN-partial-initializers.md. You can find some discussion in the list archive during the early to mid January timeframe. > _______________________________________________ > swift-evolution mailing list > [email protected] > https://lists.swift.org/mailman/listinfo/swift-evolution
