WI-H02: Enrol in the Apple Developer Program

Problem

iOS device builds, TestFlight, and App Store submission all require an Apple Developer Program membership at $99/year. It is the only compulsory recurring spend in the project (docs/architecture.md §5).

It also becomes non-optional the moment Google sign-in ships on iOS: App Store Guideline 4.8 requires Sign in with Apple wherever third-party social sign-in is offered.

In scope

Enrol in the Apple Developer Program.
Record the Team ID where the mobile build needs it.
Register the app’s Bundle ID.
Enable the Sign in with Apple capability.

Out of scope

Google OAuth client IDs and Android fingerprints — part of WI-050.
App Store listing, screenshots, review submission.
Any Expo or EAS configuration.

Definition of done

Membership active; renewal date recorded on the issue.
Team ID recorded somewhere the mobile build can reach it (not committed — see security-and-secrets.md).
Bundle ID registered and matching apps/mobile configuration.
Sign in with Apple capability enabled.

Verification

Apple’s developer portal shows an active membership, and the Bundle ID appears under Identifiers.

Notes

Defer this until you actually need a device build or a store submission. There is no reason to start a yearly billing clock early — nothing in M0 through M3 needs it, and Expo Go plus email/password auth covers development until social sign-in arrives.

The trigger to stop deferring is WI-050. Per AGENTS.md, adding Google sign-in on iOS makes Sign in with Apple mandatory, which makes this membership mandatory in the same breath.
