Firebase UI
iOS UI bindings for Firebase that connect SwiftUI/UIKit components to Firebase services for authentication and realtime data.
What is Firebase UI?
FirebaseUI for iOS is an open-source library that provides UI bindings for Firebase services, allowing developers to quickly connect SwiftUI and UIKit components to Firebase databases, authentication, and storage. It solves the problem of manually implementing Firebase integration by offering pre-built components that handle realtime data synchronization and authentication flows.
iOS developers building apps with Firebase backend services who want to accelerate development with ready-to-use UI components for authentication and data binding.
Developers choose FirebaseUI because it significantly reduces boilerplate code for Firebase integration, provides modern SwiftUI authentication components, and ensures realtime data synchronization with minimal effort compared to building custom implementations.
Overview
iOS UI bindings for Firebase.
Use Cases
Best For
- Adding Google, Facebook, or Apple authentication to SwiftUI apps
- Building chat apps with realtime message synchronization
- Displaying live-updating lists from Firebase Realtime Database
- Managing user-uploaded files with Firebase Storage UI
- Creating admin dashboards with realtime Firestore data binding
- Prototyping iOS apps quickly with pre-built Firebase UI components
Not Ideal For
- iOS apps built entirely with SwiftUI that require native, realtime data binding components for Firebase Database or Firestore
- Projects targeting iOS versions below 13.0 for UIKit or 17.0 for SwiftUI, due to version requirements in installation
- Teams using dependency managers like Carthage, as FirebaseUI only supports Swift Package Manager for SwiftUI and CocoaPods for UIKit
- Apps needing highly customized authentication UI beyond the provided SwiftUI components or support for non-standard OAuth providers
Pros & Cons
Pros
Provides pre-built SwiftUI components for major identity providers like Google, Facebook, and Apple, as shown in the modular Swift Package Manager installation options, reducing auth implementation time.
Automatically syncs UI elements with Firebase Realtime Database and Firestore for UIKit apps, updating views in realtime with minimal boilerplate code, as evidenced in the Database and Firestore READMEs.
Allows selecting only needed components via Swift Package Manager or CocoaPods, keeping app size small and dependencies focused, as detailed in the installation instructions.
Simplifies displaying and managing files from Firebase Storage with UIKit components, reducing custom code for handling uploads and downloads, per the Storage README.
Cons
SwiftUI authentication uses Swift Package Manager, while UIKit data binding relies on CocoaPods, leading to inconsistent dependency management and setup complexity, as noted in the separate installation steps.
No native SwiftUI components for Firebase Database or Firestore realtime binding; developers must use UIKit-based solutions in SwiftUI apps, limiting modern app design flexibility.
Requires manual setup of GoogleService-Info.plist, URL types for OAuth, and Firebase Console configurations, which can be error-prone and time-consuming, as detailed in the sample project setup.

MLKit - ARKitMLKit-ARKit is a Swift-based example project that integrates Firebase ML Kit's object detection with Apple's ARKit to create an augmented reality labeling experience. It processes live camera frames from ARKit to identify objects and renders corresponding 3D text labels in the AR scene using SceneKit. ## Key Features - **Real-time Object Detection** — Continuously analyzes ARKit camera frames via Firebase ML Kit on a background thread to maintain AR performance. - **3D AR Labeling** — Places detected object names as 3D text labels at ARKit feature points, anchored in the real-world view. - **Threaded Processing** — Uses a dedicated dispatch queue to run ML inference without blocking ARKit's 60 FPS rendering loop. - **Tap-to-Label Interaction** — Allows users to tap to place labels based on the most recent detection at the screen's center raycast point. ## Philosophy The project demonstrates a practical integration of on-device machine learning with augmented reality, prioritizing real-time performance by decoupling ML processing from AR rendering threads.
MLKit - ARCoreMLKit-ARCore is an augmented reality demo project that combines on-device object detection with shared 3D labeling. It enables real-time object recognition in AR using live camera frames and synchronizes the identified labels across multiple devices for a collaborative experience. ## Key Features - **Real-time Object Detection** — Uses Firebase ML Kit to analyze ARKit camera frames continuously on a background thread. - **3D AR Labeling** — Places 3D text labels at detected object positions in the AR scene using SceneKit. - **Multiplayer Synchronization** — Shares labels between phones in real-time via Firebase Realtime Database (RTDB). - **ARKit Integration** — Leverages ARCore (ARKit) for stable AR tracking and feature-point placement. ## Philosophy The project demonstrates how to efficiently combine machine learning with augmented reality by running ML inference asynchronously to maintain AR performance, while using cloud sync to create a shared AR experience.
