I have a view controller, embedded in a navigation controller, which has a button and connects me with another view controller with a button. I have ctrl dragged from the button of the second view controller to the exit in the Storyboard creating an unwind segue. While the unwind segue works as wanted (When I click the button it removes the current view controller and gets me to the first view controller) but once that happens my current view has some red lines for no apparent reason. Why does this happen? Has to do with my Xcode installation or does it have to do with Xcode in general?red lines in my view

I have Xcode 10.1 and although there is nothing fancy in my code here it is anyway: 

import UIKit

class PresentedViewController: UIViewController {
    @IBAction func myUnwindAction(unwindSegue: UIStoryboardSegue)
    {
        print("You learned to use unwindSegue")
    }
}

    Have you added constraints for your buttons? Do you have any constraints warnings or errors in your storyboard? – Paulw11 Nov 24 '18 at 20:00
  • Thank you for taking the time to answer! I have no warnings or errors in my storyboard. If you replicate exactly what I did in your Xcode, do you get those red lines too? – Korpel Nov 24 '18 at 20:05

    Have you tried running this on an actual device? – Jad Ghadry Nov 24 '18 at 20:30

    I see artifacts like this in the simulator all of the time. I think it's due to the scaling of the simulator. A real device is very unlikely to show the same results. – rmaddy Nov 25 '18 at 00:11
  • I haven't tried running it on an actual device no – Korpel Nov 25 '18 at 17:37
