There is an issue when I try to update List. CoreData is updated but List shows old value.
swift
let request = NSBatchUpdateRequest(entity: Item.entity())
request.propertiesToUpdate = ["timestamp": Date()]
do {
try viewContext.execute(request)
} catch {
let nsError = error as NSError
fatalError("Unresolved error \(nsError), \(nsError.userInfo)")
}
