ITMS-90892: Missing recommended icon error from Apple App Store - ios

Question

I get this error when submitting my app to the App Store recently.
ITMS-90892: Missing recommended icon - The bundle does not contain an alternate app icon for iPad of exactly '167x167' pixels, in .png format for iOS versions supporting iPad Pro. To support older operating systems, the icon may be required in the bundle outside of an asset catalog. Make sure the Info.plist file includes appropriate entries referencing the file. See
It's related to the alternate icons in the app structure and the names I think but has nothing to do with the assets catalog. In my app a user can choose and icon for the Home Screen.
I have 4 icons to choose and 4 sizes for each icon named e.g. - AA_appIcon#2x, AA_appIcon#2x~iPad, AA_appIcon#3x, AA_appIcon83.5#2x~iPad and it used to work fine, but now I get this error for the one name AA_appIcon83.5#2x~iPad.
It is in the correct size 167x167, so not sure what the problem is.
It just happen in the last few days, didn't happen on my previous submission a month ago.
The naming format must have recently changed or something.
Is anyone able to spot the error?

Answer 1

Here's what you need as of late 2021 if you're getting error ITMS-90890 or ITMS-90892, etc.
File Name
size
IconName#2x.png
120x120
IconName#3x.png
180x180
IconName#2x~ipad.png
152x152
IconName#3x~ipad.png
167x167
*Note the lack of capitalization on ~ipad!

Answer 2

Based on #Warpling answer, here is everything you need to setup alternate icon correctly:
1. Create the icon files
First, you'll have to create a folder named AlternateAppIcons inside your main project (where the info.plist file is located).
Now, inside the folder you've created, add the files with the names and sizes that described in the table:
File Name
Size
IconName#2x.png
120x120
IconName#3x.png
180x180
IconName#2x~ipad.png
152x152
IconName#3x~ipad.png
167x167
I'd recommend you to use Icon Set Creator to generate all sizes, then
Make sure that the file names are exactly the same (case sensitive) after the #.
When you change IconName, make sure to change it as well in the info.plist.
2. Configure info.plist
You'll have to add this to the info.plist:
<key>CFBundleIcons</key>
<dict>
<key>CFBundleAlternateIcons</key>
<dict>
<key>IconName</key>
<dict>
<key>CFBundleIconFiles</key>
<array>
<string>IconName</string>
</array>
</dict>
</dict>
<key>CFBundlePrimaryIcon</key>
<dict>
<key>CFBundleIconFiles</key>
<array/>
<key>UIPrerenderedIcon</key>
<false/>
</dict>
</dict>
<key>CFBundleIcons~ipad</key>
<dict>
<key>CFBundleAlternateIcons</key>
<dict>
<key>IconName</key>
<dict>
<key>CFBundleIconFiles</key>
<array>
<string>IconName</string>
</array>
</dict>
</dict>
<key>CFBundlePrimaryIcon</key>
<dict>
<key>CFBundleIconFiles</key>
<array/>
<key>UIPrerenderedIcon</key>
<false/>
</dict>
</dict>
3. Change the icon programmatically
All you have to do is to validate that the app supports alternate icons and change it:
guard UIApplication.shared.supportsAlternateIcons else { return }
UIApplication.shared.setAlternateIconName("IconName")
*You may want to create some enum helper like this.

Answer 3

Nevermind
I just renamed the icon from AA_appIcon83.5#2x~iPad.png to AA_appIcon#3x~ipad.png and the error went away and the icon picker still works from within the app.
