How to present view controller from right to left in iOS using Swift

Question

I am using presentViewController to present new screen

let dashboardWorkout = DashboardWorkoutViewController()
presentViewController(dashboardWorkout, animated: true, completion: nil)

This presents new screen from bottom to top but I want it to presented from right to left without using UINavigationController.

I am using Xib instead of storyboard so how can I do that ?

Answer 1

It doesn't matter if it is xib or storyboard that you are using. Normally, the right to left transition is used when you push a view controller into presentor's UINavigiationController.

UPDATE

Added timing function kCAMediaTimingFunctionEaseInEaseOut

Sample project with Swift 4 implementation added to GitHub

Swift 3 & 4.2

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

ObjC

CATransition *transition = [[CATransition alloc] init];
transition.duration = 0.5;
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[transition setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[self.view.window.layer addAnimation:transition forKey:kCATransition];
[self presentViewController:dashboardWorkout animated:false completion:nil];

Swift 2.x

let transition = CATransition()
transition.duration = 0.5
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromRight
transition.timingFunction = CAMediaTimingFunction(name:kCAMediaTimingFunctionEaseInEaseOut)
view.window!.layer.addAnimation(transition, forKey: kCATransition)
presentViewController(dashboardWorkout, animated: false, completion: nil)

Seems like the animated parameter in the presentViewController method doesn't really matter in this case of custom transition. It can be of any value, either true or false.
