Xcode slider 2 images

a slider to transition between the two images gradually. Your app should display an image view with a slider below it. There should be a label “image 1” to the left of the slider and “image 2” to the right of the slider. When the slider is all the way to the left, the image1 logo should show in the image view. As the slider moves to the right, the image1 logo should fade and an image2 logo should come into view. At the halfway point, both logos should be visible (alpha = 0.5 for both image), superimposed one on top of the other. As the slider goes all the way to the right, the image1 image should vanish and the image2 image should be the only one visible.
