[swift-evolution] KVO/KVC in Swift

[Adrian Kashivskyy]

Colin,

Until KVC/KVO is supported, you may be interested in using constructs like Observable<T>. Here are some illustrative libraries that make use of it: SwiftBond/Bond <https://github.com/SwiftBond/Bond>, slazyk/Observable-Swift <https://github.com/slazyk/Observable-Swift>.


Pozdrawiam – Regards,

If you’re working on Apple platforms, Swift does interoperate with the Objective-C KVO implementation, using the “dynamic" keyword.
