UIPageControl not visible in iOS 14
if UIPageControl not visible in iOS 14 then simply add a width constraint and assign relation "greater that or equal" or make increase width of UIPageControl.
After trying a lot, only thing work for me is just to increase the width of the UIPageControl by adding it constarints. It works fine for me.
Also there are some new features added in pagecontrol for ios14. You can refer this link: https://medium.com/better-programming/take-a-look-at-ios-14s-new-uipagecontrol-3207a10212b9
