…ndleAlternateIcons
The asset-catalog-based approach for localized iOS launcher icons relies on
actool generating a partial Info.plist that contains CFBundleIcons /
CFBundleAlternateIcons, which is then merged into the app's Info.plist.
actool only emits that partial plist when CFBundleIconName is present in
the source Info.plist; without it the alternate icons get compiled into
the .car file but the bundle never advertises them, so
-[UIApplication setAlternateIconName:completionHandler:] fails at runtime
("alternate icon name not found in bundle").
Inject `<key>CFBundleIconName</key><string>AppIcon</string>` whenever
localized icons are present so actool produces the correct merged plist
and the runtime selector wired up in CodenameOne_GLAppDelegate.m can
resolve the locale-specific icon.

Summary
actoolgenerating a partialInfo.plistcontainingCFBundleIcons/CFBundleAlternateIconsfrom the asset catalog. Xcode then merges that partial into the app's finalInfo.plistso-[UIApplication setAlternateIconName:completionHandler:]can resolve alternate icons at runtime.actoolonly emits that partial plist whenCFBundleIconNameis present in the sourceInfo.plist. Our template (vm/ByteCodeTranslator/src/template/template/template-Info.plist) only has the legacyCFBundleIconFilesarray, so the alternate icons get compiled into the.carbut the bundle never advertises them. CallingsetAlternateIconName:then fails with "alternate icon name not found in bundle" — which is the symptom a customer just hit on a build.<key>CFBundleIconName</key><string>AppIcon</string>intoInfo.plistwheneverlocalizedIconsis non-empty (the only path that needs it), soactoolproduces the merged plist with bothCFBundlePrimaryIconandCFBundleAlternateIcons, and the runtime selector wired up inCodenameOne_GLAppDelegate.mcan switch to the locale-specific icon.Verification on a customer build
