I want to get the hash value of an Any object that conforms to Hashable.

However, with this code:

    let anyValue: Any
    //...
    if let h = anyValue as? Hashable {
        return h.hashValue
    }

I'm getting this error

Protocol 'Hashable' can only be used as a generic constraint because it has Self or associated type requirements

You need to use AnyHashable instead of Hashable, which is the type erased version of the Hashable protocol created to resolve that specific error you are encountering.

if let h = anyValue as? AnyHashable {
