7 must-know SwiftUI libraries for 2025
1. SwiftUI Charts — Data Visualization, Simplified
When to Use: Analytics dashboards, progress tracking, IoT visualizations.
Example Code:
import SwiftUI
import Charts
struct SalesChartView: View {
let salesData = [
(month: "Jan", sales: 120),
(month: "Feb", sales: 150),
(month: "Mar", sales: 170)
]
var body: some View {
Chart(salesData, id: \.month) { data in
BarMark(
x: .value("Month", data.month),
y: .value("Sales", data.sales)
)
.foregroundStyle(.blue.gradient)
}
.chartYAxis {
AxisMarks(position: .leading)
}
.frame(height: 220)
.padding()
}
} Key Features:
- Native API from Apple — fully SwiftUI-compatible
- Multiple chart types (Bar, Line, Area, Pie)
- Interactive elements like tooltips and animations
- Works seamlessly with dynamic data
Real-World Benefits:
- Helps product managers and analysts quickly interpret KPIs.
- Increases engagement by making data visual rather than raw numbers.
- Boosts retention in fitness, finance, or learning apps by tracking progress visually.
2. Lottie for SwiftUI — Professional Animations
When to Use: Onboarding, celebrations, interactive feedback.
Example Code:
import SwiftUI
import Lottie
struct LottieAnimationView: UIViewRepresentable {
func makeUIView(context: Context) -> UIView {
let animationView = LottieAnimationView(name: "success-checkmark")
animationView.loopMode = .playOnce
animationView.play()
return animationView
}
func updateUIView(_ uiView: UIView, context: Context) {}
} Key Features:
- Integrates After Effects animations in JSON
- Looping and playback controls
- Lightweight and fast loading
- Cross-platform compatibility (iOS, macOS)
Real-World Benefits:
- Elevates brand personality with engaging onboarding sequences.
- Improves user delight during achievements (e.g., order placed, goal completed).
- Reduces bounce rate by creating an inviting first impression.
3. SwiftUI Introspect — Unlock UIKit Power
When to Use: When you need deep customization beyond SwiftUI’s defaults.
Example Code:
import SwiftUI
import Introspect
struct CustomTextField: View {
@State private var name = ""
var body: some View {
TextField("Enter name", text: $name)
.introspectTextField { uiTextField in
uiTextField.tintColor = .systemRed
}
.padding()
.border(Color.gray)
}
} Key Features:
- Access underlying UIKit/AppKit elements
- Apply advanced customizations SwiftUI doesn’t support
- Minimal performance overhead
- Supports iOS, macOS, tvOS
Real-World Benefits:
- Enables adding small but important UX details missing in default SwiftUI.
- Useful for teams migrating from UIKit to SwiftUI without losing key features.
- Lets you meet accessibility or branding requirements easily.
4. CombineCocoa — Reactive UI Binding
When to Use: Live search, instant form validation, reactive UI.
Example Code:
import UIKit
import Combine
import CombineCocoa
class MyViewController: UIViewController {
private var cancellables = Set<AnyCancellable>()
override func viewDidLoad() {
super.viewDidLoad()
let button = UIButton(type: .system)
button.setTitle("Tap me", for: .normal)
button.publisher(for: .touchUpInside)
.sink { _ in print("Tapped!") }
.store(in: &cancellables)
}
} Key Features:
- Turns UIKit/SwiftUI controls into Combine publishers
- Supports debounce and throttle
- Simplifies state management in reactive apps
Real-World Benefits:
- Improves real-time user experiences like live search or chat.
- Reduces lag and unnecessary updates, making apps feel snappier.
- Keeps code clean and maintainable in complex forms or filters.
5. SwiftUI Flux — Scalable State Management
When to Use: Large projects needing predictable state flow.
Example Code:
import SwiftUI
import SwiftUIFlux
struct AppState: FluxState {
var counter = 0
}
struct Increment: Action {}
func counterReducer(state: AppState, action: Action) -> AppState {
var state = state
if action is Increment {
state.counter += 1
}
return state
} Key Features:
- Unidirectional data flow architecture
- Clear separation of state, actions, and UI
- Debug-friendly with action history
Real-World Benefits:
- Helps large teams work on the same app without state conflicts.
- Makes debugging easier, saving hours in QA cycles.

@StateObject var page = Page.first()
let items = Array(1...5)
var body: some View {
Pager(page: page, data: items, id: \.self) { index in
Text("Page \(index)")
.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(Color.blue.opacity(0.8))
.cornerRadius(12)
}
.frame(height: 200)
.padding()
}
