Xamarin ios Missing App Store Icon warning

Question

I've read every question on this over the past 2 weeks that I've been struggling with this. I want to update one of the apps I have in the store and I keep getting this message and I can't submit my update.

I have set the new App store icon here

I have made sure it's 1024x1024, I have checked the color profile is sRGB and that there is no alpha in the image. The error you see was on my 14th attempt over 2 weeks and I don't know what to do anymore. I am using the latest stable release of Xcode as well.

I'm using Visual Studio for Mac 7.3 (Switched to Preview after the stable didn't work) with Xamarin iOS Version: 11.4.0.93.

I would not be asking this question here unless I've tried everything I could think of. I wish this was a coding problem, those are much easier o solve than this arbitrary problem.

Any help/advice would be greatly appreciated.

Answer 1

In xCode 9, they have added one additional app icon size with 1024px * 1024px

Go to Assets.xcassets and you can find this new addition at the bottom of your app icon image set.

Once you add app icon with 1024pt, it should fix the issue.

Answer 2

I tried every suggestion and nothing worked. Using the same build uploaded with the Application loader shipped with XCode 8.3.3 works.

Edit The warning didn't show up when uploading through Application loader, but the app store still didn't accept it :( Same error when trying to submit for review.

EDIT 2 I had to build my app with target platform 8.2 and the error went away on submitting for review.

Answer 3

A work-around is to add the icon in iTunes Connect. You only have to do it once. You will still get the warning ahen using Application Loader but it will be possible to submit the app.

Answer 4

If you, like me, used https://makeappicon.com/ to generate the different image sizes the idiom in Contents.json is wrong (as of March 2020).

Either regenerate the Assets.xcassets/AppIcon.appiconset/ with Visual Studio by adding/removing images and saving or change idiom manually from ios-marketing to ipad (in my case) and it works.
