Supabase + The Swift Kit — Auth, Database & Storage Pre-Wired

What's Pre-Wired

The Swift Kit ships these Supabase capabilities ready to use:

• SupabaseClient configured at app launch from Secrets.swift
• @Observable AuthModel binds to Supabase session changes
• Email + password sign-up / sign-in / magic-link flows
• Sign in with Apple → Supabase Auth integration
• Sign out, password reset, account deletion flows
• Starter Postgres schema (profiles table) with RLS policies
• Storage helpers for image uploads (avatars, attachments)
• Offline cache layer via SwiftData
• Error handling + user-facing messages

Setup in 5 Minutes

After cloning Swift Kit:

enum Secrets {
  static let supabaseURL = "https://xxxxx.supabase.co"
  static let supabaseAnonKey = "eyJhbGc..."  // anon public key
  // ...rest of your keys
}

Reading Auth State Anywhere

AuthModel is in the environment — any view can react to session changes:

struct RootView: View {
  @Environment(AuthModel.self) var auth

  var body: some View {
    if auth.isSignedIn {
      MainTabView()
    } else {
      SignInView()
    }
  }
}

Database Queries with RLS

Row Level Security means the database itself enforces "you can only see your own data." No server middleware needed.

// RLS policy on the database:
// CREATE POLICY "Users see own tasks" ON tasks
//   FOR SELECT USING (auth.uid() = user_id);

// In iOS code — no user_id filter needed; RLS handles it:
let tasks: [Task] = try await supabase
  .from("tasks")
  .select()
  .order("created_at", ascending: false)
  .execute()
  .value
