How to remove black screen on AppIcon - IOS

Question

I have my png AppIcon:

When I put this image in Assets.xcassets I see on my device an icon with a black background. I have seen some posts about this:

Example: iOS app icon with transparent background showing black background on device

I have only this image, I can modify this to remove the black background?

Answer 1

Remove transparency from image. App icons should be fully opaque.
