I started looking at NSConcreteValue (commit 1a9fe560) and decoding it is fine (notwithstanding implementing all the special cases). What’s the plan for instantiating concrete of NSValue though? * Class clusters seem impossible to implement in Swift * Factory methods are an API change * NSValue becoming concrete seems to muck up CF bridging (also, fragile base class problem) * I looked a little into using ManagedBuffer to size instances dynamically but it’s not much help by the time init() is called * A lookaside table works and is straightforward to implement, but is pretty ugly — Luke _______________________________________________ swift-corelibs-dev mailing list swift-corelibs-dev@swift.org https://lists.swift.org/mailman/listinfo/swift-corelibs-dev
