MultiPicker

A picker for selecting from multiple options. Or no options

SwiftUI's Picker on iOS only allows choosing exactly one option. If you need a picker that allows selecting one optional value, or multiple values from a set, you're outta luck. MultiPicker can do all three!

MultiPicker tries to make its API as close to the SwiftUI Picker's as possible.

MultiPicker supports localization and accessibility and has better default accessibility than Picker. MultiPicker supports string initializers as well as custom label views. MultiPicker has a few additions and deviations from Picker:

• Supports putting the selection indicator (checkmark) on either the leading or trailing side of options via the selectionIndicatorPosition(_:) modifier.
• Currently only supports inline and navigationLink style pickers.
• The picker style is set using the mpPickerStyle(_:) instead of pickerStyle(_:) modifier.
• Views are tagged using the mpTag(_:) modifier instead of tag(_:)
• The pushed picker list is inset grouped instead of grouped because I think that looks nicer.

Usage

Usage of MultiPicker is very similar to Picker:

struct MyView: View {
    @State private var selection: Set<Model> = []
    @State private var options: [Model]

    var body: some View {
        Form {
            MultiPicker("Choose something", selection: $selection) {
                ForEach(options) { option in
                    ModelCell(model: option)
                        .mpTag(option)
                }
            }
            .mpPickerStyle(.navigationLink)
        }
    }
}
