Xcode 8 generates broken NSManagedObject subclasses for iOS 10

I finally got mine to work. Here is what I did. (Flights is one of my entities)

I setup the xcdatamodeld as follows

And then the entity as

Then I used Editor -> Create NSManagedObject Subclass

This creates two files for my flights entity

Flights+CoreDataProperties.swift

Flights+CoreDataClass.swift

I renamed Flights+CoreDataClass.swift to Flights.swift

Flights.swift is just

import Foundation
import CoreData

@objc(Flights)
public class Flights: NSManagedObject {

}

Flights+CoreDataProperties.swift is

import Foundation
import CoreData


extension Flights {

    @nonobjc public class func fetchRequest() -> NSFetchRequest<Flights> {
        return NSFetchRequest<Flights>(entityName: "Flights");
    }

    @NSManaged public var ...
}

This appears to work for me.I could not get Codegen to work in any other way, even though I tried many of the suggestions that were out there.

Also this had me scratching my head for a while and I add it as an assist. Don’t forget with the new Generics version of the FetchRequest you can do this

let fetchRequest: NSFetchRequest<NSFetchRequestResult> = NSFetchRequest(entityName: "Flights")
