swift4: dismiss current view controller and show another controller without navigationController

Question

in my app i wanted to show a new view controller by dismissing current view controller. here is my attempt:

@IBAction func go_back_btn_pressed(_ sender: UIButton) {

    self.dismiss(animated: true, completion: {
        let vc = self.storyboard?.instantiateViewController(withIdentifier: "goOrders")
        vc!.present(vc!, animated: true, completion: nil)
        })
}

I tried doing this with this code but it show error. Error:

'NSInvalidArgumentException', reason: 'Storyboard () doesn't contain a view controller with identifier 'goOrders'' *** First throw call stack: ( 0 CoreFoundation 0x000000010eeab1e6 exceptionPreprocess + 294 1 libobjc.A.dylib 0x000000010e540031 objc_exception_throw + 48 2 UIKit 0x00000001105f33eb -[UIStoryboard instantiateInitialViewController] + 0 3 ProArt 0x000000010d5483c0 _T06ProArt25SelectPhotoViewControllerC19go_back_btn_pressedySo8UIButtonCFyycfU_ + 192 4 ProArt 0x000000010d549e3d _T06ProArt25SelectPhotoViewControllerC19go_back_btn_pressedySo8UIButtonCFyycfU_TA + 13 5 ProArt 0x000000010d4efd7d _T0Ieg_IeyB_TR + 45 6 UIKit 0x000000010fe4fd02 -[UIPresentationController transitionDidFinish:] + 1346 7 UIKit 0x00000001100d3f00 -[_UICurrentContextPresentationController transitionDidFinish:] + 44 8 UIKit 0x000000010fe53b72 __56-[UIPresentationController runTransitionForCurrentState]_block_invoke.436 + 183 9 UIKit 0x0000000110a37274 -[_UIViewControllerTransitionContext completeTransition:] + 102 10 UIKit 0x000000010fe4caee -[UITransitionView notifyDidCompleteTransition:] + 251 11 UIKit 0x000000010fe4c765 -[UITransitionView _didCompleteTransition:] + 1397 12 UIKit 0x000000010fe4ed9c -[UITransitionView _transitionDidStop:finished:] + 104 13 UIKit 0x000000010fd72f09 -[UIViewAnimationState sendDelegateAnimationDidStop:finished:] + 343 14 UIKit 0x000000010fd7354c -[UIViewAnimationState animationDidStop:finished:] + 293 15 UIKit 0x000000010fd73600 -[UIViewAnimationState animationDidStop:finished:] + 473 16 QuartzCore 0x000000010fb277a9 _ZN2CA5Layer23run_animation_callbacksEPv + 323 17 libdispatch.dylib 0x0000000113c4f848 _dispatch_client_callout + 8 18 libdispatch.dylib 0x0000000113c5a92b _dispatch_main_queue_callback_4CF + 628 19 CoreFoundation 0x000000010ee6dc99 __CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE + 9 20 CoreFoundation 0x000000010ee31ea6 __CFRunLoopRun + 2342 21 CoreFoundation 0x000000010ee3130b CFRunLoopRunSpecific + 635 22 GraphicsServices 0x00000001174e7a73 GSEventRunModal + 62 23 UIKit 0x000000010fcde0b7 UIApplicationMain + 159 24 ProArt 0x000000010d52d6f7 main + 55 25 libdyld.dylib 0x0000000113ccc955 start + 1 )

But in my app there is a identifier with "goOrders". Here is it

@Anbu.karthik I checked it. I added an image in my question. you can see this — Sarwar Jahan
You named your segue goOrders, but not the controller identifier. — Matz
1. View controller with "goOrders" as identifier should be present in storyboard. 2. It should be self.present.. not vc!.present. — Priyal

1-You have to set goOrders id here

connection less

2- Don't use a new VC to present itself

connection oriented

 self.dismiss(animated: true, completion: {
     let vc = self.storyboard?.instantiateViewController(withIdentifier: "goOrders")

     // if it will be the root
         UIApplication.shared.keyWindow?.rootViewController?.present(vc!, animated: true, completion: nil)
    })

//

or present it in viewDidAppear of the presentingVC
