SortDescriptor

@frozen
public struct SortDescriptor
extension SortDescriptor: CustomStringConvertible
extension SortDescriptor: Equatable
extension SortDescriptor: ExpressibleByStringLiteral

A SortDescriptor stores a key path and a sort order for use with sorted(sortDescriptors:). It is similar to NSSortDescriptor, but supports only the subset of functionality which can be efficiently run by Realm’s query engine.
