Best SwiftUI Framework Tips 2026

SwiftUI is Apple's brand new user interface foundation for iOS, tvOS, macOS, and watchOS. Apple released SwiftUI in 2019, and the framework has rapidly grown. SwiftUI, unlike UIKit and AppKit, is a cross-platform framework. Apple provides a method for developers to construct applications with SwiftUI quickly. SwiftUI is a user interface toolkit that allows us to create apps declaratively. Even though the concepts underlying SwiftUI differ greatly from those of UIKit and AppKit, Apple did not recreate the wheel. The framework includes everything you need to create user interfaces, such as lists, stacks, buttons, pickers, and many other components from UIKit and AppKit.

SwiftUI is compatible with the iPad, Mac, Apple TV, and Apple Watch. There are few code changes and can reuse many of the same components. With a few tweaks, the Stacks, Controls, and Layout systems will function as before. SwiftUI's concept is to learn once and apply everywhere, rather than write once and write everywhere. SwiftUI provides a slew of free visual effects for you to experiment with. Most significantly, you can animate them, and they will transition smoothly for you.

SwiftUI allows you to create beautiful apps for all Apple platforms using the power of Swift and shockingly little code. SwiftUI has been included in iOS 13 and Xcode 11, and we're already seeing apps (partially) built with it appear in the App Store. If you're new to iOS or Apple platforms, learning Swift is a good place to start. Swift is the strong programming language that drives Apple's app platforms and the language we utilize for SwiftUI. Even better if you have prior familiarity with HTML, CSS, JavaScript, React Native, or Flutter. SwiftUI is meant to work alongside UIKit and AppKit, allowing you to incorporate it gradually into your existing apps. When it comes time to design a new user interface or repair an existing one, you can use SwiftUI while keeping the rest of your codebase intact.

FLAnimatedImage SwiftUI

FLAnimatedImage is a powerful iOS animated GIF engine. It can play numerous GIFs simultaneously, at a speed equivalent to desktop browsers. FLAnimatedImage avoids delays and blockage during the initial playback loop and respects varying frame delays. It reads the frame delays of rapid GIFs in the same way as modern browsers do and handles memory pressure appropriately. FLAnimatedImage is used for the following purposes:

Those that wish to experiment with the code
Apps that do not yet enable animated GIFs
Apps that already support animated GIFs but seek a faster solution
