Is it possible to create a Picker that gives the user to not make a choice? Here is my existing code:
@FetchRequest(entity: ItemCategory.entity(), sortDescriptors: [NSSortDescriptor(keyPath: \ItemCategory.name, ascending: true)])
var categories: FetchedResults<ItemCategory>
@State private var selectedCategoryIndex = 0
/* omitted */
Section(header: Text("Category")) {
Picker(selection: $selectedCategoryIndex, label: Text("Category")) {
ForEach(0 ..< categories.count) {
if (categories[$0].name != nil) {
Text(categories[$0].name!)
}
}
}
}
This code allows the user to pick an option, but because I set the selection index to 0 it forces that choice without further interaction. When I use an optional for the index, it breaks selection completely. No item can be selected in that case.
Additionally, 'categories' is a FetchedResults collection.
