I\'m using a selectionIndicatorImage for a UITabBar, which is 49 points high, like this: UITabBar.appearance().selectionIndicatorImage = UIIm
selectionIndicatorImage
UITabBar
UITabBar.appearance().selectionIndicatorImage = UIIm
I had the same issue. I "fixed" it by subtracting the height by 1 pixel, so 48 pixels for the height of the selection image. It seems to be an iPhone X bug.
