Save checkbox button state using userdefaults in swift

view controller had two check boxes buttons 1.chekcIn 2.checkOut

am saving the checkIN [ checkbox button] status in user defaults, working fine but when am using that userdefaults key in Nextviewcontroller its always showing true and not running into false block this is the code

inHomeview controller

@IBAction func CheckInButtonClick(_ sender: UIButton) {


        for senderdata in checkINOUT {
            senderdata.setImage( UIImage(named:"uncheck1"), for: .normal)
            print("uncheck is called")

        }


        sender.setImage(UIImage(named:"check1"), for: .normal)
         prefs.set(true, forKey: "check")
    prefs.synchronize()

    }

nextviewcontroller

   override func viewDidLoad() {
        super.viewDidLoad()
{        

 let prefs:UserDefaults = UserDefaults.standard
  if  prefs.bool(forKey: "check") ==true
        {
        print("select")

        } else {

            print("unselect")
        }

 }     

check box select its execute main block if unselect execute else block
