Delete a dictionary key and value through .onDelete(perform: delete)

Question

The list below is populated with a Dictionary

@State private var currencyList: [String:String] = [:]

The delete function is as follows, however IndexSet is not applicable for a dictionary.

func delete(at offsets: IndexSet){
        print(" currency list  before \(currencyList)")
        currencyList.remove(atOffsets: offsets)
        print(" currency list after \(currencyList)")
    }

List{
            ForEach(currencyList.sorted(by: >), id: \.key){ key, value in
                HStack{
                    Image(systemName: "centsign.circle")
                    Text(value)
                    
                    Text(key)
                }
            }.onDelete(perform: delete)
        }
