Can you name protocols that provide object hashing in Swift?

In Swift, the Hashable protocol is used to ensure object hashing. It requires the implementation of the hash(into:) method, which computes the hash value of the object. There is also the Equatable protocol, which is often used together with Hashable to determine object equality.

Example:

struct Person: Hashable {
    var name: String
    var age: Int

    func hash(into hasher: inout Hasher) {
        hasher.combine(name)
        hasher.combine(age)
    }
}

Thus, Hashable is the main protocol for object hashing in Swift.
