I tried the splitting of personal and business expenses in iExpense. I'm looking for a good way to present totals for each of these in the List Section footer. Is there an easy way to achieve this (personal expenses section as an example)?

List {
                if personalExpenses.personalItems.isEmpty {
                    Section("Personal Expenses") {
                        Text("No personal expenses")
                    }
                } else {
                    Section() {
                        ForEach(personalExpenses.personalItems) { item in
                            HStack {
                                Image(systemName: "creditcard")
                                    .font(.title2)
                                    .foregroundStyle(.secondary)
                                VStack(alignment: .leading, spacing: 5) {
                                    Text(item.name)
                                        .font(.headline)
                                    Text(item.type)
                                        .font(.footnote)
                                        .foregroundStyle(.secondary)
                                }
                                .frame(maxWidth: .infinity, alignment: .leading)
                                Text("\(item.amount, specifier: "%.2f kr")")
                            }
                        }
                        .onDelete(perform: removePersonalItems)
                    } header: {
                        Text("Personal Expenses")
                    } footer: {
                        Text("Total personal expenses: \(100) PLACEHOLDER")
                    }

Try something like this

var sumPersonalExpenses: Double {
    let amounts = personalExpenses.personalItems.map { $0.amount }
    return amounts.reduce(0, +)
}
