Top 10 Must-Have SwiftUI Libraries for iOS Developers

 

SwiftUI has revolutionized iOS development, making UI design more declarative, intuitive, and efficient. However, some missing functionalities and optimizations still require additional tools. That’s where third-party libraries come in!

In this article, we’ll explore 10 powerful SwiftUI libraries that can boost your productivity and enhance app performance.

📌 1. SwiftUIX — Bridging SwiftUI and UIKit

SwiftUIX extends SwiftUI with additional UI components and utilities, filling the gaps left by Apple. It provides missing UIKit features, such as TextView, DatePicker, ActivityIndicator, and more.

🔹 Key Features:
✅ Provides missing UIKit-like controls in SwiftUI
✅ Includes advanced utilities for layout and customization
✅ Seamless integration with existing SwiftUI views

🌍 2. SDWebImageSwiftUI — Asynchronous Image Loading

SDWebImageSwiftUI makes loading and caching images from the web super easy. It integrates the power of SDWebImage with SwiftUI, ensuring smooth image rendering.

🔹 Key Features:
✅ Supports remote image downloading and caching
✅ Works seamlessly with AsyncImage and Image views
✅ GIF and animated WebP support

🔍 3. Introspect — Access UIKit Components in SwiftUI

Introspect allows you to access underlying UIKit components in SwiftUI. This is useful when you need deeper customization beyond SwiftUI’s default capabilities.

🔹 Key Features:
✅ Modify UIKit-based elements like UITableView, UITextField, and more
✅ Ideal for fine-tuning existing SwiftUI views
✅ Simple integration with .introspect()

🎬 4. Lottie for SwiftUI — Beautiful Animations

Lottie by Airbnb helps you add high-quality vector animations to SwiftUI apps. Instead of using complex sprite animations, you can use .jsonanimation files exported from After Effects.

🔹 Key Features:
✅ Lightweight, smooth animations
✅ Supports .json-based Lottie files
✅ Works with SwiftUI’s UIViewRepresentable

⚡️ 5. CombineCocoa — Reactive UIKit Bindings

CombineCocoa provides Combine framework bindings for UIKit components. If you’re working on a hybrid UIKit + SwiftUI project, this library makes event handling easier.

🔹 Key Features:
✅ Reactive event handling for UIKit components
✅ Works with Combine publishers
✅ Great for handling UI interactions dynamically

📊 6. SwiftUICharts — Stunning Data Visualization

SwiftUICharts offers a collection of customizable charts for SwiftUI applications. Whether you need bar charts, line graphs, or pie charts, this library has you covered.

🔹 Key Features:
✅ Easy-to-use chart components
✅ Beautiful animations and styling
✅ Supports dark mode

🔔 7. AlertToast — Elegant SwiftUI Notifications

AlertToast is perfect for displaying non-intrusive toast messages in SwiftUI. Whether you need a success, error, or custom alert, it provides flexible options.

🔹 Key Features:
✅ Supports multiple toast styles (success, error, loading, etc.)
✅ Customizable colors, icons, and durations
✅ Compatible with SwiftUI’s View lifecycle

🎭 8. PartialSheet — Modern Modal Presentation

PartialSheet brings UIKit’s modern sheet presentation style to SwiftUI. This is great for implementing the iOS 16+ bottom sheet experience.

🔹 Key Features:
✅ Mimics Apple’s UISheetPresentationController
✅ Fully customizable sheet height and behavior
✅ Works seamlessly with SwiftUI views

🛠 9. ViewInspector — Unit Testing for SwiftUI Views

ViewInspector allows developers to inspect and test SwiftUI viewsprogrammatically. Since SwiftUI lacks built-in view inspection, this library makes it possible to verify UI states in unit tests.

🔹 Key Features:
✅ Extracts and validates SwiftUI view hierarchy
✅ Works with XCTest for test-driven development
✅ Enables interaction testing without running the app

📖 10. SwiftUIPager — Smooth Paging UI

SwiftUIPager helps you create horizontal and vertical paged views in SwiftUI. Whether you’re building an onboarding flow or a carousel, this library simplifies the implementation.

🔹 Key Features:
✅ Supports horizontal and vertical scrolling
✅ Works with dynamic data sources
✅ Customizable animations and gestures

🎯 Conclusion

These 10 essential SwiftUI libraries can speed up development, enhance UI/UX, and optimize performance. Whether you need better animations, image handling, charts, or testing capabilities, these libraries offer powerful solutions.

🛠 Want to start using them?

Most of these libraries can be installed via Swift Package Manager (SPM):

  1. Open Xcode → File → Add Packages
  2. Enter the GitHub URL of the library
  3. Click Add Package and start using it!

Dependency Injection in iOS with SwiftUI

Image
  A Beginner-Friendly Guide to Building Modular, Testable Apps Dependency Injection (DI) is a powerful design pattern that helps you write  more modular, testable, and maintainable code . In SwiftUI, while the framework encourages composition and simplicity, adopting DI can elevate your architecture — especially as your app grows. In this post, you’ll learn: What Dependency Injection is Why it’s useful in SwiftUI apps Different DI techniques in Swift Real-world SwiftUI examples with DI Best practices and when to use DI 🧠 What is Dependency Injection? Dependency Injection  means providing an object with its dependencies from the outside instead of creating them internally. Think of it this way: instead of a class  making  its own tools, it is  handed  the tools it needs. Without DI: class UserViewModel { private var userService = UserService () } With DI: class UserViewModel { private var userService: UserService init ( userService : U...

Using Core ML with SwiftUI: Build an AI-Powered App

Image
  Artificial Intelligence (AI) is revolutionizing mobile app experiences, and with  Core ML , Apple makes it easy to integrate machine learning into iOS applications. When combined with  SwiftUI , you can create powerful, AI-driven applications with a modern and interactive UI. In this guide, we’ll explore how to integrate  Core ML  into a SwiftUI app, process images, and display real-time AI-powered results. What is Core ML? Core ML is Apple’s machine learning framework that allows developers to integrate trained models into iOS apps for tasks like  image recognition, text analysis, and object detection . Key Benefits of Core ML: ✅ Optimized for Apple hardware (fast and efficient on-device processing) ✅ Supports popular ML models like Vision, Natural Language Processing (NLP), and Sound Analysis ✅ Works  offline  without needing an internet connection ✅ Ensures privacy by running models on-device Step 1: Get a Pre-Trained Core ML Model You can do...
