Built from the library

The library screens this template wires together, in the order someone meets them. Each one installs on its own too.

First run

Three welcome pages, a reminders request, Sign in with Apple and the StoreKit 2 paywall. Runs once, then records completion.

Tabs

Today, Habits, Insights and Settings on the App Shell. Habits shows a ghost state when the list is empty.

From the tabs

What's New opens from Today and Settings. Habit details push from Today and Habits; Settings reopens the paywall, sets the theme and signs out to first run.

04

What's included

SwiftUI source you own, built on Apple frameworks only.

  • Onboarding with a real notifications request and Sign in with Apple, handing off to a StoreKit 2 paywall
  • A four-tab shell with habit detail pushes and a ghost state for an empty list

  • One root view, SubscriptionApp, with your product ids and completion key as parameters

Includes

Onboarding, Welcome, Purchase, Paywall, App Shell, Lessons, Projects, What's New, Settings. Installed together, automatically.

Requires

In-App Purchase capability

In the Build Kit

Subscription Utility (brief). Your agent builds around this template in the same design.

05

Implementation notes

How it behaves, what it handles, and the decisions behind it.

SubscriptionApp is one root view. On first launch it shows the Onboarding screen: three welcome pages, a notifications request, then the Purchase screen's StoreKit 2 paywall as the handoff. Purchasing, restoring or closing the paywall finishes onboarding and records it under a completion key, so the root switches to the home on its own.

Home is the App Shell with five tabs: Today, Habits, Projects, Insights and Profile. Today presents What's New for the 2.0 release as a sheet. Projects starts from a ghost state. Profile pushes Settings, where Manage subscription reopens the paywall full screen and Sign out clears the completion key and returns the app to first run.

Adapting it

  • Products: pass your App Store Connect ids as productIDs. Until they exist, the paywall shows its designed "plans didn't load" state and its close button still finishes onboarding.
  • Completion key: completionKey is the UserDefaults key the flow writes and the root reads. Change it to show onboarding to everyone again, for example after a redesign.
  • Sample data: onboarding copy lives in OnboardingFlowScreenExample.pages and .permission, the tabs in CadenceTab, projects in GhostStateBlockExample, release notes in BentoGridBlockExample, and the account and settings rows at the top of SubscriptionApp.swift.
  • Theme: every screen reads the Design System. Set .environment(\.spTheme, PaperTheme()) or your own theme once on SubscriptionApp to re-skin the whole app.

Notes

  • Not @main: put SubscriptionApp() in your own WindowGroup.
  • Enable the In-App Purchase capability before testing purchases.
  • Three previews ship with the file: first run, home, and home in Paper dark.
