CSStickyHeaderFlowLayout swift receiver has no segue with identifier - ios

Question

I am using CSStickyHeaderFlowLayout for Parallax Header in Swift. Xcode 7 swift 2.0 .
I tested the github swift demo. The app crashed when segueing to another view controller.
The log said:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver () has no segue with identifier 'great1'
I also tested the github object-c demo code , segue works fine .
I found out the code below has the problem . it's in appDelegate.swift for the swift demo code in the repository . Does anyone know the solution keeping segue working while having stickyParallaxHeader like the pic below .
[]
[]
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
let stickyHeaderFlowLayout = CSStickyHeaderFlowLayout()
let collectionViewController = CollectionViewController(collectionViewLayout: stickyHeaderFlowLayout)
let window = UIWindow(frame: UIScreen.mainScreen().bounds)
window.rootViewController = collectionViewController
window.makeKeyAndVisible()
self.window = window
return true
}
below is the debug log .
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver (<collectionviewmapdemo.CollectionViewController: 0x7fdbdb01d600>) has no segue with identifier 'great1''

Answer 1

I finally sort it out .
Remove the above code from project, keep
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { return true }
Make sure the layout class is CSStickyHeaderFlowLayout, see the image below .
