Summary After replacing every PNG in AppIcon.appiconset with the correct branded heart icon, the installed iOS app on a real iPhone (built and deployed via Xcode, not TestFlight web clip) still displays the default Capacitor 'blue X' placeholder icon on the home screen. The icon files in the repo are confirmed to be the new artwork, but iOS shows the old placeholder. Environment App: ImpulseAlly (Capacitor wrapper around hosted TanStack Start web app) Bundle ID: com.impulseally.app Capacitor iOS, deployment target iOS 15.0 Xcode 17E202, iOS SDK 26.4 (per derived-data log) Install method: Xcode → Run on physical device (not Safari 'Add to Home Screen', not TestFlight) Web shell URL: https://impulseally.com (server.url in capacitor.config.ts) What the user sees On the iPhone home screen, the app icon is the default Capacitor placeholder — a stylized blue 'X' / Capacitor logo on a white background. The expected icon is a sage-green rounded square with a white heart. Please ask for more information if I have not provided what you need. I have a file that I can share with everything I've tried.
