I want to provide the user with a list of categories (via picker included in a form) and the last category listed is 'Other'. If the user selects 'Other', the app is to add a field to the form for the user to enter in the new category name (which would be saved for future references).
I have been able to have the picker list presented:
Section {
Picker(selection: $courseIndex, label: Text("Course")) {
ForEach(0 ..< courses.count) {
Text(self.courses[$0]).tag($0)
} //ForEach
} // Picker
} // Section - Course
But I am unable to determine how to have the new field presented for the user to enter in the new category.
Thanks.
You can add use if
in the BodyBuilder, example:
struct ContentView: View {
@State var courseIndex: Int = 2
let courses = ["Course 1", "Course 2", "Other"]
var body: some View {
VStack {
Section {
Picker(selection: $courseIndex, label: Text("Course")) {
ForEach(0 ..< courses.count) {
Text(self.courses[$0]).tag($0)
}
}
}
if courseIndex == 2 {
Text("Show Extra")
}
}
}
}
