how do i solve NSRangeException into swift 4?

Question

I am working on app where I using swift 4. But when I want to go from first viewcontroller to second viewcontroller I got this error

* Terminating app due to uncaught exception 'NSRangeException', reason: '* -[__NSArrayI objectAtIndex:]: index 18446744073709551615 beyond bounds [0 .. 0]'

I tried to go from first viewcontroller to second viewcontroller on button click using like bellow

let vc = storyBoard.instantiateViewControllerWithIdentifier("nextView") as NextViewController
self.presentViewController(vc, animated:true, completion:nil)

But when I clicked button my app get crashed and get above nsrangeexception error

So how do I solve this error any other solution to go from first vc to second vc?

Answer 1

First of all check that your NextViewController has Storyboard ID in the storyboard:

And check that you're loading storyboard correctly:

let storyboard = UIStoryboard(name: "Main", bundle: Bundle.main)

Answer 2

If you want to navigate through Controller on StoryBoard with Identifier "nextView", then do this(this will applicable when you are trying to show one storyboard's ViewController to another storyboard ViewController):

   let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
   let vc = storyBoard.instantiateViewController(withIdentifier: "nextView") as! NextViewController
   self.present(vc, animated:true, completion:nil)

OR If you are in same storyBoard then you can simply do this - Take a button in your firstVC and ctrl+ drag a segue upto your secondVC. Then click on the segue. (the round thing on between two view controller). -

And set a identifier for that (here about is the identifier, you can give any name for this)-

Here is the code -

@IBAction func UserDetailVC(sender: AnyObject) {
        self.performSegue(withIdentifier: "segueIdentifierName(about)", sender: sender)
    }
