i need my app to be compatible with ios 9+ but the class NSPersistentContainer is only available for ios 10

  @available(iOS 10.0, *)
  private lazy var persistentContainer: NSPersistentContainer = {

  }()

Xcode is adding this, but in iOS 9 is crashing

If you need to support iOS 9, you will need to manage CoreData without NSPersistentContainer (the old way), since it is only available in iOS 10 and beyond. The alternative would be to add a check for availability -- if its iOS 10 or greater, use persistentContainer. If iOS 9, use some other storage method. You can do an availability check this way:

if #available(iOS 10.0, *) {
    // use persistent container
} else {
    // use another storage method
}
