I'm trying to create a custom Picker similar to the one in the Reminders app where users can select colors and icons for a list of reminders. I currently have this: struct CustomPickerStyle: PickerStyle {     static func _makeView<SelectionValue>(value: _GraphValue<_PickerValue<CustomPickerStyle, SelectionValue>>, inputs: _ViewInputs) -> _ViewOutputs where SelectionValue : Hashable {     }     static func _makeViewList<SelectionValue>(value: _GraphValue<_PickerValue<CustomPickerStyle, SelectionValue>>, inputs: _ViewListInputs) -> _ViewListOutputs where SelectionValue : Hashable {     } } These are automatically generated by Xcode. How should I deal with these methods? I could not find any documentation online for making a custom picker view... Thanks!
