Enum TouchBarItemPresence 

pub enum TouchBarItemPresence {
    Required = 0,
    Default = 1,
    Optional = 2,
}

SwiftUI.TouchBarItemPresence, in declaration order.

Every case carries the item’s identifier, so all three are payload cases — and payload cases are numbered before empty ones, which here means the tags are still the declaration order. That puts required first, not default.

Variants

Required = 0

Default = 1

Optional = 2
