Storyboard doesn't contain a view controller with identifier

Just for future reference:

I'm developing on iOS 6 using Storyboards.

I was having the same issue, but I could not find the "Identifier" field in the inspector. Instead, just set the field named "Storyboard ID" to what you would name the Identifier. This field can be found under the "Show the Identity inspector" tab in the inspector.

[Note - comments below indicate that some people have found that they need to (also?) set the field "Restoration ID" just below the Storyboard ID in the inspector. Clicking on "Use Storyboard ID" does not seem to be enough.]

There's an image below for reference: (in this instance I've named my identifier the same as my class)

In Xcode 7 - 13,

when you change storyboard IDs and you get errors like this,

just CLEAN your project (CMD+SHIFT+K)

Fixed! Not only the identifier in the segue must be set, in my case DrivingDetails, but also the identifier in my tableViewController must be set as DrivingDetails...check my picture:

I also removed the navigation view controller so now the 2 table view controllers are connected directly with a "push" animation.

*****EDIT for XCODE 7.0*****

you have to set the storyboardId(in this case the viewController is embedded in a Navigation controller:

let lastMinVc  = mainStoryBoard.instantiateViewControllerWithIdentifier("lastMinuteNavController") as! UINavigationController
