Re: [swift-users] still wrestling with a type conversion problem

Using a protocol with an "as?" cast convinces the compiler to do a dynamic lookup for a protocol conformance based on the value's actual type: protocol MyEncodable { func encoded() -> Any } func encode(_ value: T) -> Any { if let value = value as? MyEncodable {

[swift-users] still wrestling with a type conversion problem

I’m trying to provide some custom serialization from within a generic class. (Briefly put, I want to automatically convert types like Set to an array upon serialization, and the reverse when I read it back.) While trying things out, I was suprised by this: public func encode(_ value:T) -> Any {
