The return type of functions that do not return normally, that is, a type with no values.
@frozen enum NeverUse Never as the return type when declaring a closure, function, or method that unconditionally throws an error, traps, or otherwise does not terminate.
func crashAndBurn() -> Never {
fatalError("Something very, very bad happened")
}var id: ObjectIdentifierThe stable identity of the entity associated with this instance.
var id: NeverThe stable identity of the entity associated with this instance.
static func != (Self, Self) -> Boolstatic func ... (Self) -> PartialRangeFrom<Self>Returns a partial range extending upward from a lower bound.
static func ... (Self) -> PartialRangeThrough<Self>Returns a partial range up to, and including, its upper bound.
static func ... (Self, Self) -> ClosedRange<Self>Returns a closed range that contains both of its bounds.
static func ..< (Self) -> PartialRangeUpTo<Self>Returns a partial range up to, but not including, its upper bound.
static func ..< (Self, Self) -> Range<Self>Returns a half-open range that contains its lower bound but not its upper bound.
static func <= (Self, Self) -> BoolReturns a Boolean value indicating whether the value of the first argument is less than or equal to that of the second argument.
static func > (Self, Self) -> BoolReturns a Boolean value indicating whether the value of the first argument is greater than that of the second argument.
static func >= (Self, Self) -> BoolReturns a Boolean value indicating whether the value of the first argument is greater than or equal to that of the second argument.
