B2B iOS App Boilerplate: SSO-Friendly Auth + Entitlements
A business-facing iOS app lives or dies on two things: getting a company's employees signed in without friction, and gating features by the plan their employer bought. The Swift Kit ships both — Supabase auth that plays nicely with Sign in with Apple and email, plus RevenueCat multi-tier entitlements that map cleanly to seat-based and plan-based access.
The Swift Kit is a b2b ios app boilerplate priced at $99 one-time (unlimited commercial projects, lifetime updates, 14-day refund) built around the two things business apps actually need: SSO-friendly authentication and tiered entitlements. Auth runs on Supabase with email and Sign in with Apple, while RevenueCat handles multi-tier entitlements so you can gate features by the plan a company purchased. API keys are proxied server-side through Supabase Edge Functions, so nothing sensitive ships inside the binary your customers' IT teams will inspect.
Why B2B iOS apps need a different starting point
Consumer app boilerplates assume one user signs up, pays for themselves, and unlocks one premium tier. A business-facing app breaks every one of those assumptions. The person installing the app is rarely the person who pays. Access is granted by an employer's plan, not an individual card. And the buyer's IT team may want to control how employees authenticate. The Swift Kit was assembled with those realities in front of it: Supabase auth gives you a real Postgres user table you can extend with org and role columns, Sign in with Apple covers the privacy-conscious enterprise login path, and RevenueCat's multi-tier entitlements let you model 'Team', 'Business', and 'Enterprise' access without rewriting your gating logic each time sales invents a new plan.
SSO-friendly auth, honestly scoped
Be clear-eyed about what 'SSO-friendly' means here. The Swift Kit ships Supabase email auth and Sign in with Apple out of the box, behind a feature flag you can toggle. That covers the common B2B entry points and gives you a clean Supabase identity layer to build on. True enterprise SSO — SAML, Okta, Azure AD, SCIM provisioning — is configured on the Supabase side, not pre-wired in the app. The kit gives you the foundation (a server-backed auth layer and a user table you own) so adding an OIDC provider is a configuration task, not an architecture rebuild.
- Email + Sign in with Apple shipped and flag-toggled
- Supabase Postgres user table you can extend with org_id and role
- Edge Functions enforce per-user rate limiting server-side
- SAML/OIDC providers added via Supabase config, not app rewrites
Entitlements that map to how companies buy
In B2B, a feature isn't unlocked because a user tapped a paywall — it's unlocked because their company is on a plan that includes it. RevenueCat's multi-tier entitlements are the right primitive for this. You define entitlements once, attach them to offerings, and check them anywhere in SwiftUI. The 6 feature-flag modules (onboarding, auth, paywall, push, AI, Apple Sign-In) let you ship a self-serve trial flow for smaller teams while leaving room to wire account-level provisioning for enterprise deals later.
- Multi-tier entitlements model Team / Business / Enterprise plans
- One entitlement check gates SwiftUI features app-wide
- Paywall module toggles off cleanly for sales-led deals
- RevenueCat receipts and renewals handled, not hand-rolled
What a B2B build still requires from you
The Swift Kit gets you to a signed-in, entitlement-gated, secrets-safe iOS app fast — but a serious B2B product needs work the boilerplate deliberately doesn't presume. Org-level data modeling (who belongs to which workspace), admin dashboards, seat management, audit logging, and procurement-friendly compliance documentation are yours to build. What you save is the undifferentiated 6-8 weeks of plumbing: auth, secure key handling, payment infrastructure, design system, and onboarding. You spend your real time on the org logic and the workflow that makes your app worth a company's purchase order.
Swift Kit vs. building your B2B auth and entitlements from scratch
| Feature | The Swift Kit ($99) | Build from scratch |
|---|---|---|
| Cost | $99 one-time | Weeks of senior engineering time |
| Server-backed auth (email + Apple) | Shipped on Supabase | Build and secure yourself |
| Secrets kept out of the binary | Edge Function proxy included | Design and host your own proxy |
| Multi-tier entitlements | RevenueCat, pre-wired | Hand-roll receipt + plan logic |
| Extensible user table for orgs/roles | Postgres, yours to extend | Schema from zero |
| Enterprise SAML/OIDC SSO | Config on Supabase, not pre-wired | Full custom integration |
| Time to signed-in, gated app | Hours to days | Many weeks |
