How do I make this work? Rather than duplicating the MenuItem struct, I would like to be able to pass in any object conforming to Storage If I change 'var items: [Storage]' to just [Wallet] or [Bank] it works fine. But when it is [Storage], ForEach complains I'm new to Swift and trying hard to understand Hashable to resolve this issue but I need help.

protocol Storage { var index: Int { get } var name: String { get } // ... }

struct Bank: Storage, Hashable { let index: Int let name: String // ...

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

}

struct Wallet: Storage, Hashable { let index: Int let name: String // ...

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

}

struct MenuItem: View { // I need this to except objects conforming to the Storage protocol var items: [Storage]

var body: some View {
    VStack(spacing: 0) {
        // ... Type 'any Storage' cannot conform to 'Hashable'

        ForEach(items, id: \.self) {item in
            // ... This thows the error
        }
    }
}

}

var banks = [Bank]() var wallets = [Wallet]()

protocol Storage: Hashable { 
  var index: Int { get } 
  var name: String { get } // ...
}

does not work?

No. I did try that. I get the same error

Your Storage is a protocol, using var items: [Storage], is like saying items is of an array of Storage Protocols.
