I am getting this CoreData error. I have no idea why I'm getting this error. I'm not using any Transformable types. I see nothing in my code indicating that I'm using transformable properties. I let Xcode set up CoreData by selecting the Use Core Data option when I created my project. The other similar questions do not help because the answers have to do with code that look like anything that I can find that Xcode created when the project was created. The project does not crash when this error appears in the debug window. I am using Xcode 11.3 and Google Maps SDK for iOS for iOS 12, and it's running on an iPhone 8 device with iOS 13.3.

At some point, Core Data will default to using "NSSecureUnarchiveFromData" when nil is specified, and transformable properties containing classes that do not support NSSecureCoding will become unreadable.

This is the code that triggers the error:
do {
storeAddresses = try managedObjectContext.fetch(Address.fetchRequest())
} catch {
print(error)
}
I am using the following core data objects:
Address entity
position attribute
type Integer 16
text attribute type String
timestamp attribute type Date
route relationship destination Route inverse addresses
Route entity
timestamp attribute type Date
title attribute type String
addresses relationship destination Address inverse route
I have the following code for managed object classes:
public class Address: NSManagedObject {
}
extension Address {
@nonobjc public class func fetchRequest() -> NSFetchRequest<Address> {
return NSFetchRequest<Address>(entityName: "Address")
}
@NSManaged public var text: String?
@NSManaged public var timestamp: NSDate
@NSManaged public var position: Int16
@NSManaged public var route: Route?
}
public class Route: NSManagedObject {
}
extension Route {
@nonobjc public class func fetchRequest() -> NSFetchRequest<Route> {
return NSFetchRequest<Route>(entityName: "Route")
}
@NSManaged public var timestamp: NSDate
@NSManaged public var title: String?
@NSManaged public var addresses: NSSet?
}
// MARK: Generated accessors for addresses
extension Route {
@objc(addAddressesObject:)
@NSManaged public func addToAddresses(_ value: Address)
@objc(removeAddressesObject:)
@NSManaged public func removeFromAddresses(_ value: Address)
@objc(addAddresses:)
@NSManaged public func addToAddresses(_ values: NSSet)
@objc(removeAddresses:)
@NSManaged public func removeFromAddresses(_ values: NSSet)
}
