Horizontal flip animation in Keynote

I want to perform a horizontal flip animation between two images in Keynote. How I can do this? The flipping should swipe images

1. Insert the two images (other object or group to be transitioned).

2. Select the first side and from the animation inspector add a Build Out effect of Flip. Disable Bounce.

   

3. Select the second side and from the animation inspector add a Build In effect of Flip. Disable Bounce.

4. Choose Build Order and set the second build (the build in) to Start: With Build 1.

   

5. Set the second side to be in front of the first side by right-clicking on the second side and choosing Bring to Front. Position the two sides on top of each other.
