Icon specified in the info.plist not found under top level app wrapper

This error is showing while uploading binary to iTunes store.

Error: Icon specified in info.plist not found.
Solution: your icon name mismatch in info.plist file.

I've putted image app-prod@2x.png in my resources folder, but in info.plist my icon name is
app-prod@2X.png. {difference look  X letter is capitalized in info.plist}


Hope this works for you.
Cheers :)
