My app icon is showing with white borders, how do I remove it? this is happening only when I try to build the application for ios, on the android system this does not happen

I tried modifying the alpha channel but it didn't work.

It looks like your image has some white (or transparant) color on the edges. If that's the case I would open the image in a image program, zoom in, find these spots and fill them with the background color.
