A Comparative Study on the Adoption of Swiftui Over Uikit in Modern Ios Application Development

Abstract

The evolution of mobile application development frameworks has a direct impact on software quality, maintainability, and development efficiency. Apple’s SwiftUI framework introduces a declarative user interface paradigm that contrasts with the imperative UIKit framework traditionally used in iOS development. While SwiftUI has gained rapid industry adoption, empirical evaluations comparing it with UIKit remain limited. This study presents a systematic and metric-driven comparison of SwiftUI and UIKit, focusing on architectural design, development productivity, code complexity, state management reliability, and runtime performance. An experimental methodology was employed in which equivalent application modules were implemented using both frameworks and evaluated using quantitative software engineering metrics. The results demonstrate that SwiftUI significantly reduces development time and code complexity while maintaining comparable runtime performance. These findings provide empirical evidence supporting SwiftUI as a scalable and future-oriented framework for modern iOS application development.
