Overview

Social Feed is a learning-focused SwiftUI application inspired by modern photo-sharing products. It explores a complete social-app structure: multi-step registration, authentication, profiles, a Firestore feed, photo selection, post creation, search, messaging, notifications, reels-style UI, and tab navigation.

What it demonstrates

• Firebase Authentication for account creation, login, session restoration, and sign-out
• Firestore-backed user profiles and timestamp-ordered posts
• A multi-step SwiftUI registration flow
• Photo selection with PhotosUI and post composition
• Profile editing, user statistics, post grids, stories, and feed cards
• Real-time chat updates using Firestore snapshot listeners
• Search, notification, upload, reels, and messaging feature modules
• MVVM-style organization across authentication, feed, profile, search, and upload flows

Run locally

Requirements

• Xcode 16 or newer
• iOS 18.5+ target
• A Firebase project with Authentication and Firestore enabled

Setup

1. Clone the repository and open InstagramTutorial.xcodeproj.
2. Select your signing team and use your own bundle identifier.
3. Register the app in Firebase and replace the Firebase configuration with your own.
4. Enable Email/Password authentication.
5. Create Firestore collections for users, posts, and messages.
6. Build and run.

Current scope

This repository is an educational implementation rather than a production social network. Uploaded images are encoded into Firestore documents for demonstration; a production version should use Firebase Storage or another object store. Error handling, moderation, pagination, security rules, and media processing also need production hardening.

Good next steps

• Move media uploads to object storage
• Add Firestore security rules and emulator-backed tests
• Paginate the feed and search results
• Improve surfaced error states instead of logging failures
• Add accessibility identifiers and meaningful UI tests
• Remove user-specific Xcode state files from version control
