How to solve “Missing Marketing Icon. iOS Apps must include a 1024x1024px”

Question

I am uploading app in iTunes from Xcode 9.0...This error is showing on the last step. How to solve this? 1024x1024px icon is present in my icons list

Answer 1

I was stuck at this problem for about 2 hours. I had a icon present in my icon list but it keeps on failing. The problem was that the PNG had alpha channel enabled. Open up photoshop and save your image without alhpa/transparency.
