One codebase, real store app
The iOS app loads your published Firebase Studio URL inside a native WebView. There is no second project to maintain and no code export.
Why wrapping beats rebuilding for Firebase Studio apps
Keep shipping from Firebase Studio
Publish again and the app updates instantly. Only changes to the native shell itself (icon, new native feature) need a store update.
Native features on top
Push notifications, offline screen, native sharing, biometric login, QR scanner, in-app purchases and deep links are single settings or one-line JavaScript calls.
App Store approval guarantee
Apple App Store approval guarantee – or your money back within 14 days. 96.4% of all WebViewGold apps get approved by the review teams on the first attempt.
What you need
- A published Firebase Studio app on a public HTTPS URL (yourapp.web.app or, better, your own domain)
- An Apple Developer Program ($99 per year) to submit to Apple App Store
- Xcode on a Mac – or the WebViewGold Cloud Builder in your browser (no Mac needed)
- WebViewGold for iOS ($109 one-time, free updates)
- A privacy policy page, a 1024 × 1024 px icon and 30 to 60 minutes
Firebase Studio to App Store: the walkthrough
Seven steps, no coding. Most people finish the native part in under an hour.
Publish your Firebase Studio app to a production URL
Publish from Firebase Studio to Firebase App Hosting (or Firebase Hosting). The app is served on a web.app or firebaseapp.com address. Publish again to ship changes. Workspace preview URLs are private and temporary. Publish first. Custom domain: Add a custom domain in the Firebase console under Hosting and set the DNS records shown. See why a custom domain before submission is worth it.
Make it store-ready
Add a privacy policy page, an account deletion option (if users can sign up), and remove builder badges or "download our app" banners. Run the free App Store readiness check on your URL: it flags mixed content, missing viewport tags, builder preview domains and other blockers in seconds.
Get WebViewGold for iOS
One-time payment, free updates. You receive the ready-made Xcode project. If you do not own a Mac, activate the WebViewGold Cloud Builder and do everything in the browser.
Insert your URL and brand the app
Open Config.swift (or the Cloud Builder form) and paste your published URL. Set the app name, upload your icon, pick splash screen and status bar color. No coding needed.
Switch on native features
Enable push notifications, the offline screen, social-login handling, pull-to-refresh, biometric login or the QR scanner with single settings. Everything is optional.
Build and upload
In Xcode: Product → Archive → Distribute to App Store Connect. In the Cloud Builder: click Build, the upload to App Store Connect is done for you.
Create the App Store listing
In App Store Connect add name, subtitle, description, keywords, screenshots, privacy policy URL and the App Privacy answers. Add a demo account in the review notes if needed.
Submit for review
Apple reviews most apps within 24 to 48 hours. Answer reviewer questions in Resolution Center if any come up. Our approval guarantee covers you.
Firebase Studio-specific checks before you submit
These are the points that come up most often with Firebase Studio projects (Next.js, React, Angular or Flutter web with Firebase Auth, Firestore and App Hosting).
- Firebase Google sign-in uses pop-ups or redirects; inside the app enable WebViewGold's Social Login Helper. Sign in with Apple through Firebase is handled automatically.
- Add the account deletion flow (Firebase provides a "Delete User Data" extension) before you submit.
- Add a privacy policy page; list Firebase Analytics or Crashlytics data collection in the store privacy forms.
Let Firebase Studio do the store-readiness work
Paste this into Firebase Studio and let it apply the changes reviewers look for. Review the result, then publish.
Prompt to paste into Firebase Studio
Prepare this app for publishing as a native iOS and Android app (it will run inside a native WebView wrapper): add /privacy and /terms pages linked from the footer; add a "Delete my account" action that removes the Firestore data and the Firebase Auth user after confirmation; make all pages responsive from 320px to tablet widths with 44px tap targets; remove external promotional links; add a retry state for failed requests; set the title to the app name (max 30 characters).
App Store review: the rules that matter for Firebase Studio apps
Apple reviews behavior, not tooling. Nobody is rejected for using Firebase Studio; apps are rejected for the points below.
- 4.2
Minimum Functionality
The app must offer more than a repackaged website. Responsive layout, native navigation and at least one native capability (push notifications, offline screen, native sharing, biometric login) make the difference. WebViewGold switches these on with one setting each.
- 2.1
App Completeness
No placeholder content, no dead links, no crashes. If content sits behind a login, provide a demo account in the App Review notes.
- 5.1.1
Privacy
A public privacy policy URL is mandatory. Apps that let users create accounts must also let them delete the account inside the app.
- 4.8
Login Services
If you offer Google, Facebook or another third-party login, you must also offer an equivalent option that limits data collection, such as Sign in with Apple. Email/password login alone needs nothing extra.
- 3.1.1
In-App Purchase
Digital goods and subscriptions sold inside the app must use Apple's In-App Purchase. Physical goods and real-world services can keep Stripe or PayPal.
- 2.3
Accurate Metadata
Screenshots, description and app name must match what the app does. Do not mention other platforms or "beta" in the listing.
Native features your Firebase Studio app gets in the iOS app
Every feature is optional and documented step by step in the WebViewGold for iOS documentation.
Push notifications
Remote push via OneSignal or Pushwoosh, local scheduled pushes via a JavaScript call, permission prompt at the moment you choose.
DocumentationSocial Login Helper
Google and Facebook logins work inside the app; Sign in with Apple is handled automatically.
DocumentationUniversal Links
Links from emails (magic links, password resets) open directly in the app.
DocumentationIn-app purchases
App Store subscriptions and one-time purchases via RevenueCat, triggered from your web app.
DocumentationOffline screen and fallback
A native "Try again" screen when the user is offline, or a local HTML fallback.
DocumentationLoading indicator and splash
Keep the launch screen until the web app is loaded, or show a native spinner.
DocumentationBiometric login
Face ID / Touch ID gate from a JavaScript call.
DocumentationQR and barcode scanner
Native scanner that returns the result to your web app.
DocumentationNative share sheet and haptics
Share dialog and haptic feedback from your web app.
DocumentationCustom CSS and JavaScript
Hide website-only elements and inject code when loaded inside the app.
DocumentationPre-flight checklist for App Store
Tick these off and the review is a formality. The free readiness check verifies the technical half automatically.
- HTTPS everywhere: App Transport Security blocks plain http:// content and invalid certificates.
- Responsive layout from 320 px to iPad widths. Apple also opens iPhone apps on an iPad during review.
- Privacy policy URL ready (a page inside your web app is fine).
- Account deletion available in the app if users can sign up.
- Demo login for the reviewer if content is behind authentication.
- No "Download our app" banners, no links to other app stores, no builder badges inside the app.
- A 1024 × 1024 px app icon without transparency and rounded corners (Apple adds the mask).
- Screenshots for the current iPhone sizes (and iPad if supported) taken from the real app.
- App name of 30 characters or fewer, a subtitle and keywords prepared.
- Export compliance answered (an app that only uses HTTPS qualifies for the standard encryption exemption).
Frequently asked questions
Can a Firebase Studio app be published in the stores?
Yes. Publish to Firebase Hosting, insert the public URL into WebViewGold and submit the native builds. Firebase keeps serving auth and data.
Do I need a Mac to publish an iOS app?
Not with the WebViewGold Cloud Builder: configuration, build and upload to App Store Connect happen in the browser. If you own a Mac, the Xcode project works out of the box.
How long does Apple review take?
Most submissions are reviewed within 24 to 48 hours. First submissions and apps with logins sometimes get a question from the reviewer; answer it in Resolution Center and the review continues.
What if Apple rejects the app?
Rejections name the guideline and the reason, and you can resubmit as often as needed. WebViewGold comes with an App Store approval guarantee: if Apple rejects the app for a non-content reason, you get your money back within 14 days of purchase.
Do I have to resubmit the app every time I change something in Firebase Studio?
No. The app loads your published URL, so content and feature changes you publish in Firebase Studio are live in the app immediately. A new store version is only needed when the native shell changes, for example a new app icon or an added native feature.
What does it cost in total?
$109 one-time for WebViewGold for iOS (free updates) plus the Apple Developer Program ($99 per year). Optional: the Cloud Builder add-on if you want to build in the browser, or the Full Service package where our team configures, builds and submits the app for you.
