swift: thread 1: exc_bad_instruction (code = exc_1386_invop, subcode = 0x0)

Question

Я понятия не имею, почему я всегда встречаю эту ошибку!

Снова!

Кстати, я использую Xcode 7.3

, если такой код, не будет ошибкой

case 2: 
      self.recipesImageView.image = UIImage(named: noodles.image) 
      title = self.noodles.name 

`

но если такой код," лапша "превратить в" закуски "

case 2: 
      self.recipesImageView.image = UIImage(named: snacks.image) 
      title = self.snacks.name 

Тогда будет ошибка:

"thread 1: exc_bad_instruction(code=exc_1386_invop,subcode=0x0)"

if segue.identifier == "showRecipesDetail" { 
     // var obj = segue.destinationViewController as! DetailTableViewCell 
     if let indexPath = self.tableView.indexPathForSelectedRow { 
      let destinationController = segue.destinationViewController as! DetailViewController 

      if segment.selectedSegmentIndex == 0 { 
       destinationController.recipes = recipes[indexPath.row] 
       destinationController.category = self.category 
       print(category) 
      } 
      if segment.selectedSegmentIndex == 1 { 
       destinationController.noodles = noodles[indexPath.row] 
       destinationController.category = self.category 
       print(category) 
      } 
      if segment.selectedSegmentIndex == 2 { 
       destinationController.noodles = snacks[indexPath.row] 
       destinationController.category = self.category 
       print(category) 
      } 
      if segment.selectedSegmentIndex == 3 { 
       destinationController.noodles = noodles[indexPath.row] 
       destinationController.category = self.category 
      } 
      if segment.selectedSegmentIndex == 4 { 
       destinationController.noodles = noodles[indexPath.row] 
       destinationController.category = self.category 
      } 
     } 
    } 

} 

ниже код является неправильным в

if segment.selectedSegmentIndex == 2 { 
      destinationController.noodles = snacks[indexPath.row] <----this line is wrong 
      destinationController.category = self.category 
      print(category) 
} 

этот код должен быть

destinationController.snacks = snacks[indexPath.row]
