SwiftUI has revolutionized iOS app development by offering a declarative and intuitive way to build user interfaces. To further enhance your SwiftUI development experience and make your apps stand out, various third-party libraries have emerged. In this blog post, we’ll dive into 10 SwiftUI libraries that can supercharge your iOS app development journey. Each library comes with a code example explained line by line to help you understand its implementation.
1. AlamofireImage
AlamofireImage is an image downloading and caching library built on top of Alamofire, simplifying the process of fetching and caching images. It provides features like automatic caching, image decompression, and prioritized downloading.
Example
import SwiftUI
import AlamofireImage
struct ImageView: View {
var body: some View {
VStack {
Text("AlamofireImage Example")
Image(uiImage: UIImage(named: "placeholder")!)
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 200, height: 200)
.afImageCache()
}
}
}
2. Kingfisher
Kingfisher is another powerful image downloading and caching library that is widely used in the iOS community. It supports various image formats, caching strategies, and customizable loading indicators.
Example
import SwiftUI
import Kingfisher
struct ImageViewWithKingfisher: View {
var body: some View {
VStack {
Text("Kingfisher Example")
KFImage(URL(string: "https://example.com/image.jpg"))
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 200, height: 200)
}
}
}
3. SDWebImageSwiftUI
SDWebImageSwiftUI is an integration of the popular SDWebImage library into SwiftUI. It provides asynchronous image loading, caching, and displaying with support for placeholder images and image transformation.
Example
import SwiftUI
import SDWebImageSwiftUI
struct WebImageView: View {
var body: some View {
VStack {
Text("SDWebImageSwiftUI Example")
WebImage(url: URL(string: "https://example.com/image.jpg"))
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 200, height: 200)
}
}
}
4. ViewInspector
ViewInspector is a library that enables SwiftUI view hierarchy introspection, helping developers with debugging and UI testing. It allows you to access and modify the properties of a SwiftUI view.
Example
import SwiftUI
import ViewInspector
struct InspectableView: View {
@State private var count = 0
var body: some View {
VStack {
Text("ViewInspector Example")
Text("Count: \(count)")
}
.onTapGesture {
count += 1
}
.inspect { view in
try view.find(ViewType.Text.self, "Count: 0")
}
}
}
5. SwiftUIX
SwiftUIX is a collection of extensions and utilities that expand the capabilities of SwiftUI. It provides additional components, modifiers, and functionality not present in the standard SwiftUI library.
Example
import SwiftUI
import SwiftUIX
struct ExtendedView: View {
var body: some View {
VStack {
Text("SwiftUIX Example")
Button(action: {}) {
Label("Submit", systemImage: "arrow.right.circle.fill")
}
.buttonStyle(PlainButtonStyle())
}
}
}
6. Pulley
Pulley is a versatile library that simplifies the creation of custom drawer and bottom sheet interfaces. It provides a smooth and interactive experience for users to reveal additional content.
Example
import SwiftUI
import Pulley
struct PulleyView: View {
var body: some View {
PulleyView(content: Text("Main Content")) {
Text("Drawer Content")
.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(Color.gray)
}
}
}
7. AlertToast
AlertToast offers an elegant way to display toast messages and alerts in SwiftUI applications. It supports various customization options and animations for presenting messages to users.
Example
import SwiftUI
import AlertToast
struct ToastView: View {
@State private var showToast = false
var body: some View {
VStack {
Text("AlertToast Example")
Button("Show Toast") {
showToast = true
}
.alertToast(isPresented: $showToast, alert: {
AlertToast(type: .complete(.green), title: "Success")
})
}
}
}
8. SwiftEntryKit
SwiftEntryKit is a flexible library for displaying custom popup alerts, banners, and notifications in your SwiftUI app. It supports various presentation styles and animations.
Example
import SwiftUI
import SwiftEntryKit
struct CustomPopupView: View {
var body: some View {
VStack {
Text("SwiftEntryKit Example")
Button("Show Popup") {
showCustomPopup()
}
}
}
func showCustomPopup() {
var attributes = EKAttributes.centerFloat
attributes.entryBackground = .color(color: .white)
let customView = YourCustomPopupView()
SwiftEntryKit.display(entry: customView, using: attributes)
}
}
9. Motion
Motion is a library that adds smooth animations and transitions to your SwiftUI views. It simplifies the process of creating complex animations and adds delightful user interactions.
Example
import SwiftUI
import Motion
struct AnimatedView: View {
@State private var scale: CGFloat = 1.0
var body: some View {
VStack {
Text("Motion Example")
Circle()
.frame(width: 100, height: 100)
.scaleEffect(scale)
.onTapGesture {
withAnimation(.spring()) {
scale = scale == 1.0 ? 1.5 : 1.0
}
}
}
}
}
10. ColorPicker
The ColorPicker library provides a SwiftUI color picker view, allowing users to select colors easily. It supports a wide range of customization options and integrations.
Example
import SwiftUI
import ColorPicker
struct ColorPickerView: View {
@State private var selectedColor: Color = .red
var body: some View {
VStack {
Text("ColorPicker Example")
ColorPicker("", selection: $selectedColor)
.frame(width: 100, height: 100)
}
}
}
