Section {
    TextField("Amount", value: $checkAmount, format: Locale.current.currency?.identifier ?? "USD"))
        .keyboardType(.decimalPad)

    Picker("Number of people", selection: $numberOfPeople) {
        ForEach(2..<100) {
            Text("\($0) people")
        }
    }
}

should fix code like this

Section {
    TextField("Amount", value: $checkAmount, format: .currency(code: Locale.current.currency?.identifier ?? "USD"))
        .keyboardType(.decimalPad)

    Picker("Number of people", selection: $numberOfPeople) {
        ForEach(2..<100) {
            Text("\($0) people")
        }
    }
}
