Swift NumberFormatter if value is 0 return empty string

Question

I have the following code:

struct Food {
    var name: String
    var energy: Float = 0
    var water: Float = 0
}

struct FoodItemView: View {
    
    @State var newFoodItem = Food(name: "")
    private var numberFormatter = NumberFormatter()

    var body: some View {
        Form {
            Section(header: Text("Basics").fontWeight(.bold)) {
                TextField("Name", text: $newFoodItem.name)
                TextField("Energy (C)", value: $newFoodItem.energy, formatter: numberFormatter)
                .keyboardType(.numberPad)
                TextField("Water (g)", value: $newFoodItem.water, formatter: numberFormatter)
        }
    }
}
               

How do I make it so that, the value displayed in my TextFields would be an empty string if the bound value is 0, rather than explicitly displaying the 0?

Answer 1

Set .zeroSymbol property of NumberFormatter.

struct FoodItemView: View {
    
    @State var newFoodItem = Food(name: "")
    private var numberFormatter = NumberFormatter()
    
    init() {
        numberFormatter.zeroSymbol = "" //<< Here
    }
