SwiftUI was announced in 2019 with promises of a mature, production‑grade UI framework for Apple platforms. After 7 years and into 2026, it still feels like a perpetual beta, turning initial excitement into deep professional frustration.

Core issues include unpredictable performance, fragile layout, a chaotic data flow, and a lack of backward compatibility that forces shims and workarounds. The mix of @State, @Binding, ObservedObject, and later the Observation framework and @Observable macro creates a confusing, reactive system that often updates views in ways developers cannot predict.

The layout engine, built on size negotiation, is fragile. Custom sidebars, floating views, and even Apple’s own broken SwiftUI tutorial break under new Xcode releases, forcing developers to use GeometryReader and lose declarative benefits, only to rewrite coordinates as the layout system changes.

API stability is another problem: code is littered with #available checks, and feature parity with UIKit remains uneven. Apple’s promise to end महत्वपूर्ण Auto Layout battles has left many developers making excuses for bugs, fighting layout issues, and doing QA for Apple, keeping SwiftUI in a perpetual beta state.
