AppIcon bug in Xcode

When I debug build the app, it runs well. However, if you do a profile or release build, you get a bug in the app icon.

The contents of the bug are "The stickers icon set or app icon set named "AppIcon" did not have any applicable content."

My assets have AppIcon, but I wonder why the bug says that there is no AppIcon only when it is released or profiled.
