Partial pagecurl animation with swift

问题

I'm looking for a way to indicate a pagecurl animation on an uiview to give the user a hint that he can scroll through some pages. It should be some kind of partial pagecurl.

The problem is that I don't know how to do that. I found some tutorials but only for objective c and I don't know how transfer it into swift:

 [UIView animateWithDuration:1.0
                     animations:^{
                         CATransition  * animation = [CATransition animation];
                         [animation setDuration:1.2f];
                         animation.startProgress = 0.0;
                         animation.endProgress   = 0.6;
                         [animation setTimingFunction:UIViewAnimationCurveEaseInOut];
                         [animation setType:@"pageCurl"];
                         [animation setSubtype:@"fromRight"];
                         [animation setRemovedOnCompletion:NO];
                         [animation setFillMode: @"extended"];
                         [animation setRemovedOnCompletion: NO];
                         [[self.animatedUIView layer] addAnimation:animation
                                                      forKey:@"pageFlipAnimation"];
                          [self.animatedUIView addSubview:tempUIView];

                     }
     ];

UIView.animate(withDuration: 1.0, animations: {
    let animation = CATransition()
    animation.duration = 1.2
    animation.startProgress = 0.0
    animation.endProgress = 0.6
    animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseOut)
    animation.type = "pageCurl"
    animation.subtype = "fromRight"
    animation.isRemovedOnCompletion = false
    animation.fillMode = "extended"
    self.animatedUIView.layer.add(animation, forKey: "pageFlipAnimation")
    self.animatedUIView.addSubview(tempUIView)
})

I think you can use UIPageViewController. I did something like this for my project. This tutorial is helpful.
