iOS app icon requirement with XCode 9

As a reminder, for the iOS apps build with XCode 9, the app icon size of 1024x1024 has be added as marketing icon in the project resource (xcarchive file):

iOS Apps must include a 1024x1024px Marketing Icon in PNG format. Apps that do not include the Marketing Icon cannot be submitted for App Review or Beta App Review.

Please remember to update it for your project if you build your app with XCode 9.

Plus, we noticed some projects deliver their app icon with round corners, which is not necessary:

Keep icon corners square. The system applies a mask that rounds icon corners automatically.

Please correct that in next release if this is the case for your project.
