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

Now onwards we need to add a new icon in our project with the size 1024X1024. Please see below-attached image. This issue was stared from WWDC 2017.

Note: - Do not upload or use the beta version (mac os or Xcode) for app upload. As per Apple recommendation. I already got mail from Apple about this.
