Welcome to this blog post on the top advantages and disadvantages of using SwiftUI compared to UIKit! In this post, we will take a look at the main advantages and disadvantages of using SwiftUI over UIKit, and help you decide which framework is the best fit for your needs.
- SwiftUI is easier to learn and use than UIKit, especially for developers who are new to iOS development. SwiftUI uses a declarative syntax that is easier to read and understand, and it has fewer concepts and APIs to learn.
- SwiftUI code is more concise and declarative than UIKit code, which makes it easier to read and maintain. With SwiftUI, you can build your UI using simple statements that describe what you want to achieve, rather than having to write long blocks of imperative code.
- SwiftUI has better support for live previews, which makes it easier to design and iterate on your UI. With SwiftUI, you can see your changes in real-time as you make them, and you can even preview your UI on multiple devices and orientations at the same time.
- SwiftUI has better integration with other frameworks, such as Combine and RealityKit, which makes it easier to build more advanced features. With SwiftUI, you can use these frameworks to build features such as reactive programming, asynchronous tasks, and augmented reality, without having to deal with the complexity of UIKit.
- SwiftUI has better support for accessibility and localization, which makes it easier to build apps that are accessible and localized for different languages and regions. SwiftUI has built-in support for dynamic type, accessibility labels, and localization, which makes it easier to build apps that are accessible and localized for different languages and regions.
- SwiftUI has replaced Interface Builder with Canvas, an interactive interface editor. With Canvas, the visual part of your code is automatically generated, and any changes you make to your visual presentation elements will automatically appear in your code. This eliminates the need to use @IBOutlets and ensures that your application will not crash if you forget to update an association.
- In place of AutoLayout, SwiftUI uses layout elements such as HStack, VStack, ZStack, Groups, and Lists to define the layout of your views. These elements provide a more intuitive and reliable way to create layouts, as they always produce a valid layout and do not suffer from issues like ambiguous or unsatisfiable layouts.
- Additionally, SwiftUI has replaced storyboards with code, making it easier to create reusable views and avoid conflicts that can arise when working on a project as a team. Overall, SwiftUI offers a more efficient and intuitive approach to building user interfaces for iOS applications.

- SwiftUI is a newer framework than UIKit, so it has less documentation and community support. While the SwiftUI community is growing rapidly, it is still smaller than the UIKit community, which means that you may have a harder time finding answers to your questions or solutions to your problems.
- SwiftUI is not fully backward-compatible with UIKit, so you may need to re-implement certain features if you are migrating an existing app from UIKit to SwiftUI. While SwiftUI has many features that are similar to UIKit, it also has some fundamental differences, which means that you may need to re-implement certain features or use UIKit or other frameworks to achieve certain effects.
- SwiftUI does not have as many customization options as UIKit, so you may need to use UIKit or other frameworks to achieve certain effects. While SwiftUI has many built-in views and controls, it does not have as many customization options as UIKit, which means that you may need to use UIKit or other frameworks to achieve more advanced or customized layouts.
- SwiftUI has less flexibility than UIKit, so you may need to use UIKit or other frameworks to achieve more complex or customized layouts.
- SwiftUI has less support for legacy iOS versions, so you may need to use UIKit or other frameworks to support older devices.
- One major drawback of SwiftUI is that it currently only supports iOS 13 and Xcode 11. This means that if you choose to use SwiftUI in your app, you will have to abandon users of older versions of iOS. This can be a significant issue for developers who want to reach as wide an audience as possible, as there are still many users who have not yet upgraded to the latest version of iOS.
- Another issue with SwiftUI is that it is relatively new, and there is not yet a large volume of information or solutions available on platforms like Stack Overflow. This can make it more difficult to resolve complex issues that you may encounter while using SwiftUI.
- Finally, SwiftUI does not currently allow you to examine the view hierarchy in Xcode Previews. This can make it more difficult to debug and troubleshoot issues with your app’s layout and behavior.
Overall, while SwiftUI offers many benefits and improvements over UIKit, it also has some limitations and drawbacks that developers should be aware of.
