A paywall is a sales page that has to load in a second. Lead with one benefit, show clear plans, and wire it to StoreKit 2 the right way.

**TL;DR.** An in-app purchase paywall is a focused sales screen: one hero benefit, two or three clear plan options with a highlighted default, social proof, and the required restore and terms links. Build the UI free from a VP0 design, wire it to StoreKit 2 (Product, purchase, Transaction), and follow App Store rules. Apple takes 15 to 30 percent, so the paywall is where your revenue is won or lost.

Building an in-app purchase paywall in SwiftUI? The short answer: it is a sales page that has to convert in seconds, so lead with one benefit, show two or three clear plans, and wire it to StoreKit 2 properly. Build the UI free from a VP0 design, the free iOS design library for AI builders, clone it into your AI tool, then connect StoreKit. Apple takes a cut of every sale, so this one screen is where your revenue is decided. By the numbers, about 76% of developers [now use or plan to use AI tools](https://survey.stackoverflow.co/2024/ai) in their work.

## Who this is for

This is for indie developers and vibe coders adding subscriptions or one-time purchases to an iOS app who want a paywall that looks credible and converts, without paying for a monetization UI kit.

## What a paywall has to get right

A paywall is focused on purpose. One hero benefit at the top, stated as an outcome, not a feature list. Two or three plan options with a clearly highlighted default, usually annual, and honest pricing. A little social proof, a rating or a count, to lower risk. And the non-negotiables: a restore purchases option and links to terms and privacy. The [StoreKit documentation](https://developer.apple.com/documentation/storekit) covers the purchase APIs, the [App Store Review Guidelines](https://developer.apple.com/app-store/review/guidelines/) cover the in-app purchase rules, and the [Apple Human Interface Guidelines](https://developer.apple.com/design/human-interface-guidelines) cover the layout. Apple takes 15 to 30 percent depending on your program, so every point of conversion matters.

| Element | Job | Get it right |
|---|---|---|
| Hero benefit | Sell the outcome | One line, not a feature dump |
| Plan options | Make the choice easy | 2 to 3, default highlighted |
| Social proof | Lower risk | Rating or honest count |
| Restore and terms | Pass review | Always present and visible |
| StoreKit wiring | Actually charge | Product, purchase, Transaction |

## Build it free with a VP0 design

Pick a paywall or monetization screen in VP0, copy its link, and prompt your AI builder:

> Build a SwiftUI paywall from this design: [paste VP0 link]. A hero benefit headline, three subscription options with the annual plan highlighted, a short social-proof line, a primary purchase button, and restore and terms links. Wire it to StoreKit 2 using Product and purchase, and match the palette and spacing from the reference.

## Wire StoreKit 2 the right way

With StoreKit 2 the flow is clean: load your products, present them, call purchase on the chosen one, and verify the returned transaction. Add a StoreKit configuration file in Xcode so you can simulate products and test the full purchase, restore, and cancel paths before you ever submit. Handle the states honestly, loading, success, failure, and already-subscribed, and always offer restore so a returning user is never stuck. Test the unhappy paths as carefully as the happy one, because that is where reviews and refunds come from.

## Common mistakes

The first mistake is a feature dump instead of one clear benefit. The second is too many plans, which freezes the decision. The third is missing restore or terms, which fails review. The fourth is not testing with a StoreKit configuration file before submitting. The fifth is paying for a paywall kit when a free VP0 design plus StoreKit does it.

## Key takeaways

- A paywall is a focused sales screen: one benefit, a few plans, a clear default.
- Always include restore and terms; without them you fail App Store review.
- VP0 gives you the paywall UI free, ready to wire to StoreKit 2 with Claude Code or Cursor.
- Test purchase, restore, and cancel with a StoreKit configuration file before submitting.
- Apple takes 15 to 30 percent, so every conversion point counts.
