Mobile: The Future of Declarative UI Frameworks | Sentry

The mobile ecosystem has become increasingly diverse with various frameworks and tools emerging for developers, many of which rely on JavaScript. However, native Android and iOS platforms have recently adopted declarative UI frameworks, joining React Native and Flutter in this approach. Android's Jetpack Compose and iOS's SwiftUI are built around programming languages instead of XML files, reducing the need for explicit references to widgets and logic attachment. This shift towards declarative development brings numerous benefits, including easier theming, state management, dynamic layouts, and conditional rendering, as well as improved code diffs and unit testing capabilities. However, it also introduces new challenges, such as smaller community support, performance issues, and limitations in building complex UIs.
