Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value after the code iCarouselView.type = .cylinder

This code is under override func viewDidLoad() {

@majdalrifai iCarousel is written in Objective-C, and that error can only be generated by Swift code.

My guess is that you have created an implicitly unwrapped @IBOutlet for your iCarouseView, and that this hasn’t been correctly hooked up in your Storyboard so that it’s nil at the point when you try to set the type property.
