 Cannot Connect Storyboard Unwind Segue
By : Neel Gandhi

I wish this helpful for you You need to have an IBAction defined on a view controller that takes an argument of type "UIStoryboardSegue *". Something like this: code :
@interface MyViewController
...
- (IBAction)unwindFromConfirmationForm:(UIStoryboardSegue *)segue {
}
...
@end
@IBAction func unwindToViewController(segue: UIStoryboardSegue) {
//code
}

 Dismiss Popover using Unwind Segue in Xcode Storyboard
By : Cindy Summers
Date : March 29 2020, 07:55 AM
To fix this issue Unwind segues use runtime searching by first asking the parent view controller to walk up the chain of view controllers presented via segue until it finds the correct unwind method. But there is no chain here since the popover was created programmatically rather than with a popover segue. No callbacks are occurring since there is no segue link back to the parent view controller. Unwind segues are an abstracted form of delegation, so this would be similar to forgetting to set the delegate and not receiving any callbacks. code :
- (void)prepareForSegue:(UIStoryboardPopoverSegue *)segue
sender:(id)sender {
self.popover = segue.popoverController;
}
- (BOOL)shouldPerformSegueWithIdentifier:(NSString *)identifier sender:(id)sender {
if (self.popover.isPopoverVisible) {
[self.popover dismissPopoverAnimated:YES];
return NO;
} else {
return YES;
}
}

Unwind Segue in Xcode 6.1.1 with storyboard
By : user2838640

Hope this helps Got it working. If you are presenting from a NavigationController or TabBarController(unsure about the TabBarController), you need to subclass the navigation controller and add the unwind segue to that. In storyboard don't forget to change the class of your navigation controller. My view hierarchy was NavController -> TableController -> DetailController. After adding method to custom NavBar class add it to the VC you want to RETURN to. You will then be able to ctrl-drag to exit. I consider this a bug, as once it is hooked up I was able to delete the subclass and return to stock NavigationController and it still worked.

"no segue with identifier" when using 'Unwind Segue' with a storyboard reference
By : Harald Kirsebom

I hope this helps . You don't need to create any segues to the reference itself.
Once your second storyboard contains a reference to the first storyboard, any unwind functions defined in the first storyboard are available.

How to work with Storyboard Unwind Segue in Mac OS X
By : Fox Rother

Any of those help Unlike iOS where the screen is the real estate. In Mac, we have plenty of space. You see, from the builtin segues, most of them are just a way to show up a new dialog. And, when you are done with it. You don't really need to go back somewhere, all you need is a way to close that dialog down.
To decoupling things a bit further, instead of unwinding which require selector from other view controller. They encourage us to use dismissController: from the view controller we want to close it down. This method will dismiss the view controller using the same segue animator that presented it.
