CoreData generated class - Is there memory leak risk of not using weak in inverse relationship?

When come to circular reference, it comes with risk of memory leaking, by not using a weakkeyword. For instance :-

Memory leak without using weak

class Human {
    deinit {
        print("bye bye from Human")
    }
    
    init(_ pet: Pet) {
        self.pet = pet
    }
    
    let pet: Pet
}

class Pet {
    deinit {
        print("bye bye from Pet")
    }
    
    var human: Human?
}

print("start of scope")

if true {
    let pet = Pet()
    let human = Human(pet)
    pet.human = human
    
    print("going to end of scope")
}

print("end of scope")

/*
 Output:
 
 start of scope
 going to end of scope
 end of scope
 */

No memory leak by using weak

class Human {
    deinit {
        print("bye bye from Human")
    }
    
    init(_ pet: Pet) {
        self.pet = pet
    }
    
    let pet: Pet
}

class Pet {
    deinit {
        print("bye bye from Pet")
    }
    
    weak var human: Human?
}

print("start of scope")

if true {
    let pet = Pet()
    let human = Human(pet)
    pet.human = human
    
    print("going to end of scope")
}

print("end of scope")

/*
 Output:
 
 start of scope
 going to end of scope
 bye bye from Human
 bye bye from Pet
 end of scope
 */

In CoreData, when setup 2 entities with one-to-many relationship, it is recommended to have inverse relationship too. Hence, CoreData will generate the following class with circular reference.

extension NSHolidayCountry {

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

    @NSManaged public var code: String
    @NSManaged public var name: String
    @NSManaged public var holidaySubdivisions: NSOrderedSet

}

extension NSHolidaySubdivision {

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

    @NSManaged public var code: String
    @NSManaged public var name: String
    @NSManaged public var holidayCountry: NSHolidayCountry?

}

NSHolidaySubdivision is having inverse relationship to NSHolidayCountry. However, such inverse relationship is not marked as weak, based on CoreData generated class.

I was wondering, does this come with a memory leak risk? Should I, add a weak keyword manually in entity NSHolidaySubdivision's holidayCountry ?
