In what ways do you think updating a managed object is different in Swift 3? Do you run into specific problems which didn't occur in Swift 2? If so, please share more details.

Try this
let empId = "001"
let fetchRequest:NSFetchRequest<NSFetchRequestResult> = NSFetchRequest.init(entityName: "EmpDetails")
let predicate = NSPredicate(format: "empId = '(empId)'")
fetchRequest.predicate = predicate
do
{
let test = try context?.fetch(fetchRequest)
if test?.count == 1
{
let objectUpdate = test![0] as! NSManagedObject
objectUpdate.setValue("newName", forKey: "name")
objectUpdate.setValue("newDepartment", forKey: "department")
objectUpdate.setValue("001", forKey: "empID")
do{
try context?.save()
}
catch
{
print(error)
}
}
}

print(error)

Pass unique id in variable "id"(Unique variable created in Core data model) and all the variable as you want to update values:
func context() -> NSManagedObjectContext {
let context=(UIApplication.shared.delegate as!AppDelegate).persistentContainer.viewContext
return context
}
func save() {
(UIApplication.shared.delegate as! AppDelegate).saveContext()
}
func UpdateCartByTestId(id:Int64,name:String) {
let fetchRequest =
NSFetchRequest<NSManagedObject>(entityName: "Update")
fetchRequest.returnsObjectsAsFaults = false
fetchRequest.predicate = NSPredicate(format:"id == %d",id)
let result = try? context().fetch(fetchRequest)
if result?.count == 1 {
let dic = result![0]
dic.setValue(id, forKey: "id")
dic.setValue(name, forKey: "name")
save()
}
}
