Answer 1

Thanks @salman for an answer with the help of Salman's answer I got a solution for an infinite solution without jerking issue when carousel type is linear

Please follow the steps given below.

1. Define timer for handle scrolling

_ = Timer.scheduledTimer(timeInterval: 4, target: self, selector: #selector(self.handleTimer), userInfo: nil, repeats: true)

2. Write the delegate method of the carousel and handle wrap type with the help of wrap we solve jerk issue.

    func carousel(_ carousel: iCarousel, valueFor option: iCarouselOption, withDefault value: CGFloat) -> CGFloat {
        switch option {
        case .wrap:
            return 1
        default:
            return value
        }
    }

3. Method to handle scrolling

    func handleTimer() {
        var newIndex = self.carousel.currentItemIndex + 1

        if newIndex > self.carousel.numberOfItems {
            newIndex = 0
        }

        carousel.scrollToItem(at: newIndex, duration: 0.5)
    }
