ios,set swipe views, when swipe from right to left, the view appear from bottom to top

See below photo, I didn't add any code in project.

I just create a new project, and create two "ViewController.swift", and added 2 view Controllers in "Main.StoryBoard". Set 3 view controllers background as blue, yellow and Purple.

Then, I add swipes on the view controllers. So when I swipe on the view, I can get into another view.

I run this project, and it works. I can swipe right or left between 3 views. However, when the new view get into and replace current view, the new view appeared from bottom to top, not from right to left or from left to right.

How can solve this? I hope the view appear from right to left. enter image description here
