Use of unresolved identifier 'NSCoreDataCoreSpotlightDelegate'

Hello guys.

Recently, I'm trying to add CoreSpotlight Integration to my app, and I wrote the following code:

public func createDataMainContext() -> NSManagedObjectContext {
    let bundles = [Bundle(for: PeopleToSave.self)]
    guard let model = NSManagedObjectModel.mergedModel(from: bundles) else {
        fatalError("Model not found")
    }
    let psc = NSPersistentStoreCoordinator(managedObjectModel: model)
    let storeDescription = NSPersistentStoreDescription(url: storeUrl!)
    storeDescription.shouldMigrateStoreAutomatically = true
    storeDescription.shouldInferMappingModelAutomatically = true
    let coreDataCoreSpotlightDelegate = NSCoreDataCoreSpotlightDelegate(forStoreWith: storeDescription, model: model)
    storeDescription.setOption(coreDataCoreSpotlightDelegate, forKey: NSCoreDataCoreSpotlightExporter)
    psc.addPersistentStore(with: storeDescription) { _,_ in }
    let context = NSManagedObjectContext(concurrencyType: .mainQueueConcurrencyType)
    context.persistentStoreCoordinator = psc
    return context
}

But then Xcode said that "Use of unresolved identifier 'NSCoreDataCoreSpotlightDelegate", and now I've got no idea what to do with it 😟
