Stop Using isLoggedIn! Real iOS Login with SSL Pinning & JWT (SwiftUI)

🔐 Production-Grade iOS Authentication & Security (SwiftUI)

In this video, I walk through how real-world iOS apps implement secure authentication — beyond simple login screens and isLoggedIn flags.

You’ll learn how to design a production-ready security architecture using SwiftUI, focusing on security, scalability, and user experience.

📌 What this video covers:

✅ SSL Pinning

Why HTTPS alone is not enough

How SSL pinning protects against Man-in-the-Middle attacks

✅ JWT Authentication

Access token vs Refresh token

Why short-lived access tokens are important

Stateless authentication explained

✅ Refresh Token Flow

Automatic token refresh

Secure session persistence without re-login

Handling expired tokens correctly

✅ Secure Storage

Keychain for sensitive data (tokens)

UserDefaults only for non-sensitive UX data

Why passwords should never be stored

✅ Login State Persistence

How real apps decide “logged-in” state

Avoiding isLoggedIn = true anti-patterns

Auto-login and logout flows

✅ SwiftUI Architecture

MVVM

Async/Await networking

Clean separation of concerns
