I am creating an iOS application for iPads with Swift 5, Xcode 13.1. Last time I changed my icons by replacing images in Assets.xcassets. However, suddenly the app icon became not properly displayed on my iPad for some reason. Now the app icon is just a grid.

There are two weird things happening:

1. The icons are actually properly displayed when testing with simulators.

2. Then I reversed all of the modifications using GitHub, but the app still does not show its icon, even with using all files that used to show the icon properly.

I have tried:

1. rebooting my MacBook Pro and iPads (mini 6th & pro 11 inch.)
2. clean build,
3. made sure App Icons Source was appropriately selected
4. recreate new iOS app icon in Assets with Xcode
5. tested with other icon files that are confirmed to be working with other apps
6. re-install Xcode
7. Tried with my iPhone

However, none of the above solved the problem. I would appreciate it very much if I could know what is happening and how I can show the app icon properly.

I updated iPads and iPhones to iOS 15.1, and the problem solved completely!! Now all icons are displayed properly.
