Use reflection. Match against only dictionaries with string keys. Match against only objects conforming to some dictionary-with-string-keys-like protocol. Match against only objects conforming to an NSKeyValueCoding protocol with a `value(forKey:)` requirement. Don't actually implement matching; just use it as an abstraction for things like CloudKit and Core Data. There are options. -- Brent Royal-Gordon Architechies _______________________________________________ swift-corelibs-dev mailing list swift-corelibs-dev@swift.org https://lists.swift.org/mailman/listinfo/swift-corelibs-dev
