Hello

In the WeSplit project,

Paul demonstrated how to use segmented with Pickers. I understand this is smart and easy https://www.hackingwithswift.com/books/ios-swiftui/adding-a-segmented-control-for-tip-percentages

Section {
    Picker("Tip percentage", selection: $tipPercentage) {
        ForEach(tipPercentages, id: \.self) {
            Text($0, format: .percent)
        }
    }
    .pickerStyle(.segmented)
}

However , an array of tip percentages have limited users' options when it comes to tipping.

If I still want to use TextField for tips, is there a value: xxx, format: .xxxxx method for me to input any tip percent or even Int/Double value for tips ?

Thanks

Thank you @roosterboy, reading it now !

Have a nice weekend.

It seems this way it could work:

struct ContentView: View {

    @State  private var numberOfPeople = 1
    @State  private var bill = 0
    @State  private var tipPercent: Double

    var body: some View {
        NavigationView {
        Form{
            Section{

         TextField ("How much tip do you like to leave ?", value:self.$tipPercent, formatter: NumberFormatter())
                Section {
                    Text("\(tipPercent)")
                }
                }}}
               }

 struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()

Except the Preview Section is telling me :

1, 'ContentView' initializer is inaccessible due to 'private' protection level

2, Missing argument for parameter 'tipPercent' in call

As the error message indicates, you need to provide an initial value for tipPercent

Thank you @roosterboy. It works now !

Can I say that, by providing tipPercent an initial value, I effectively initialized it ?
