So I currently have an service extension setup that write data to CoreData (Or I believe it does). Given that the xcdatamodelid is shared with both targets can I not write in one and read in the other?

Here is how I create the NSPersistenContainer in both targets:

lazy var persistentContainer: NSPersistentContainer = {
    let container = NSPersistentContainer(name: "commonName")
    container.loadPersistentStores(completionHandler: { (storeDescription, error) in
        if let error = error as NSError? {
            fatalError("Unresolved error \(error), \(error.userInfo)")
        }
    })
    return container
}()

And here is how I add an entity:

func addEntity(uid: String, status: String) {
    let context = persistentContainer.viewContext
    if let entity = NSEntityDescription.entity(forEntityName: EntityNames.alertNotificationEntity, in: context) {
let managedObj = NSManagedObject(entity: entity, insertInto: context)
        managedObj.setValue(uid, forKey: CoreDataEntityKeys.AlertNotificationEntity.uid)
        managedObj.setValue(status, forKey: CoreDataEntityKeys.AlertNotificationEntity.status)
        do {
            try context.save()
        } catch {
            print(error.localizedDescription)
        }
    }
}

I don't get any fatal when a notification comes in and the addEntity method is used.

In my appDelegate when I try to print the values out it says it's just empty.

What am I doing wrong? Is it not possible to share the CoreData between the Applications target and the service extensions target?

Edit: I should add that I have already tried to setup what is outlined in How to access CoreData model in today extension (iOS)

Data/File between the app and extension can be shared using App group. Check Share data between app and extension

    App groups have already been setup and UserDefaults sharing between the two targets (main app and NSE) is working but NOT CoreData though. – sbrioux Mar 18 '18 at 16:31
