swift – Why Does iOS Alternate Icons Not Working Correctly

I used to be making an iOS app utilizing Swift

However by some means my alternate icons not working correctly

Once I faucet the button, it says “You will have modified the icon for “App”.”, however what it modified is nothing however empty icon.
