SwiftUI array of objects with AnyView

Question

I'm new to SwiftUI and im trying some things out. I have a List which is being build out of an Array. I want to create a Navigation depending on the row that is clicked. So I've build a struct with the following:

struct DiscoverItem: Hashable, Equatable {
    var name: String
    var destination: AnyView
}

let arr = [
    DiscoverItem(name: "Catalogus", destination: AnyView(ProductList(products: []))),
    DiscoverItem(name: "Locations", destination: AnyView(LocationList()))
]

However Xcode is saying

Type 'DiscoverItem' does not conform to protocol 'Equatable'

How can I solve this or which way is the proper way to do this?

It is due to AnyView which disables automatic conforming to those protocols (because does not conform to them).

Here is possible solution:

struct DiscoverItem: Hashable, Equatable {
    static func == (lhs: DiscoverItem, rhs: DiscoverItem) -> Bool {
        lhs.id == rhs.id
    }

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

    let id = UUID()
    var name: String
    var destination: AnyView
}
