Missing required icon files in build from Xcode 9

Make sure Copy Bundle Resources is under [CP] Embed Pods Frameworks and [CP] Copy Pods Resources in Build Phases.

I have the same problem. Check this: solution

Just add this code below to your podfile:

post_install do |installer|
      installer.aggregate_targets.each do |target|
        copy_pods_resources_path = "Pods/Target Support Files/#{target.name}/#{target.name}-resources.sh"
        string_to_replace = '--compile "${BUILT_PRODUCTS_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}"'
        assets_compile_with_app_icon_arguments = '--compile "${BUILT_PRODUCTS_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}" --app-icon "${ASSETCATALOG_COMPILER_APPICON_NAME}" --output-partial-info-plist "${BUILD_DIR}/assetcatalog_generated_info.plist"'
        text = File.read(copy_pods_resources_path)
        new_contents = text.gsub(string_to_replace, assets_compile_with_app_icon_arguments)
        File.open(copy_pods_resources_path, "w") {|file| file.puts new_contents }
      end
    end

and then run in console pod install

EDIT:

If its not working, locate your app's xcarchive file, right click >> show package contents, navigate to products >> applications >> your application's name >> show package contents. Locate the info plist from here, and change the BuildMachineOsBuild to 16A323. This basically tricks the computer into thinking it's on an older OS.. problem seems to stem from High Sierra. Then submit the app.

After trying some of the suggestions above which removed some errors, in my case I could solve all of them by renaming the AppIcon in the project's .xcassets file. The project uses CocoaPods and some of these pods contain example projects with AppIcon in it as well. So instead of removing these I simply renamed my AppIcon and changed the reference in project settings. From that moment on, it finally processed after hours of trial and error.

When looking in the Pods xcassets files with Xcode they were missing the marketing icon and the iPad Pro icon definition (older libraries). These were the exact errors I got. In the archive the files are now named AppIcon and so are they referenced in Info.plist file.

PS: to find out if you have multiple AppIcon assets, you can use find . -name AppIcon*

• Archive project as usual
• On latest build in organizer from context menu pick 'Reveal in finder'
• On archive file in finder from context menu pick 'Show package contents'
• Open terminal and CD to this folder
• Run this command in terminal:

find Products/ -name Info.plist -print0 | xargs -0n1 plutil -replace BuildMachineOSBuild -string 16A323

Then proceed with regular upload. At the end you'll see a warning popup about missing marketing icon but build will go through

I had same issue. Fixed by removing CFBundleIcons~ipad key from info.plist

Check here

In my case one of Pods has .xcassets with resources. Errors with icons gone after excluding this pod. Finally pod was fixed by replacing .xcassets with .bundle.

Part of .podspec change log:

-  s.resources = '**/*.xcassets'
+  s.resources = '**/*.bundle'

As @Daniel Kuta said the solution is:

1. locate your app's xcarchive file,
2. show package contents >> products >> applications >> your application's name >> show package contents.
3. Locate the info plist from here, and change the BuildMachineOsBuild to 16A323.

However above solution will remove first three errors, but not the last one warning.

Please move AppIcon to default Assets.xcassets instead Icon.xcassets.

Also here are some tips... https://developer.apple.com/library/content/qa/qa1686/_index.html

I suggest to keep old icon names even if apple says that it isn't mandatory.
