SwiftUI at 7 Years: Still Feels Like a Beta
Original: SwiftUI After 7 Years
Why This Matters
SwiftUI is Apple's primary UI framework for all platforms; persistent quality issues directly impact the iOS and macOS developer ecosystem.
Seven years after its 2019 debut, SwiftUI continues to suffer from layout inconsistencies, performance gaps vs. UIKit, unstable data flow APIs, and poor backward compatibility, according to a detailed critical analysis published July 20, 2026 by developer Yakov Manshin.
Developer Yakov Manshin published a lengthy critical assessment of SwiftUI on July 20, 2026, arguing that Apple's declarative UI framework remains unfit for senior-level production use despite seven years of development. Manshin points to four core systemic failures: unpredictable layout behavior, performance deficits compared to UIKit, a constantly shifting data-flow model, and backward-compatibility breakage that forces developers to maintain shims and workarounds.
As a concrete example, Manshin highlights Apple's own official SwiftUI 'Landmarks' tutorial project, which he states is currently broken when run on macOS. He also presents a head-to-head performance comparison showing UIKit outperforming SwiftUI in real-world scenarios.
Manshin contextualizes SwiftUI's origins as a competitive response to React, React Native, and Flutter rather than a developer-first initiative, arguing this reactive origin led to a framework optimized for marketing rather than engineering rigor. He draws a broader conclusion: Apple's engineering culture has shifted from the 'uncompromising craftsmanship' of the Cocoa/Aqua/Auto Layout era toward a 'good enough' product philosophy. He notes that after seven years—a span comparable to the gap between the original iPhone and the iOS 7 redesign—the excuse that SwiftUI is 'still young' is no longer credible.
