How to dismiss modal ViewController from right to left?

Question

In Objective-C, I want to dismiss modal ViewController from right to left.

Now I can move from left to right on modal. But I don't know how to dismiss this modal VC from left to right like push screen transition.

Here is a code which moves from a-ViewController to b-ViewController.

bViewController *nextVC = [[bViewController alloc] initWithNibName:nil bundle:nil];

CATransition *transition = [CATransition animation];
transition.duration = 0.5; 
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
transition.type = kCATransitionPush ; 
[transition setSubtype:kCATransitionFromLeft];
[[nextVC.view layer] addAnimation:transition forKey:@"TransitionTest"]; 
//[self presentViewController:nextVC animated:YES completion:nil];
//if it's possible, I want to use upside's cord.(don't addSubView) but I don't know how to do it)
[self.view addSubview:nextVC.view] ;

Objective-C

CATransition *transition = [CATransition animation];
transition.duration = 0.4;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[self.view.window.layer addAnimation:transition forKey:nil];
[self dismissViewControllerAnimated:NO completion:nil]; 

Swift 5

let transition = CATransition()
transition.duration = 0.5
transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
transition.type = CATransitionType.push
transition.subtype = CATransitionSubtype.fromRight
self.view.window!.layer.add(transition, forKey: nil)
self.dismiss(animated: false, completion: nil)
