Try this:

You can change view controller by index of VCArr.

var index = 0

func changeSlide() {
    index + 1
    if index < self.VCArr.count {
        setViewControllers([VCArr[index]], direction: .forward, animated: true, completion: nil)
    }
    else {
        index = 0
        setViewControllers([VCArr[0]], direction: .forward, animated: true, completion: nil)

    }
}
