Give Your Coding Agent Eyes: Screenshot-Driven SwiftUI Iteration

This article discusses a screenshot-driven approach for coding agents to iterate on SwiftUI interfaces more effectively. It highlights the limitations of blind agent-assisted UI work and proposes a concrete feedback loop: using deterministic preview harnesses, fake data, debug routes, and simulator screenshots to make targeted adjustments. The author references WWDC26 Xcode agent workflows, emphasizes starting with small visual targets, and provides a model example (FlairCardModel) to represent various UI states. Practical advice includes creating reusable preview fixtures, capturing screenshots as deliberate inputs, and keeping useful scripts after visual work. The article is focused on improving agent-assisted UI development in SwiftUI, making it relevant to IT/TECHNOLOGY.
