preview-build is a plugin marketplace that builds and captures SwiftUI previews from Xcode and SPM for agent-side visual analysis.
About
preview-build is a one-plugin Claude marketplace from Iron-Ham that wraps the XcodePreviews toolchain for iOS developers shipping SwiftUI apps. Instead of describing layouts in prose, you register the marketplace so your agent can compile previews and capture frames for visual comparison, regression checks, and design feedback loops. It supports full Xcode workspaces, SPM packages, and loose Swift files, which fits small teams that do not want a separate screenshot pipeline. Use it during active UI work when you already have previews defined in code. It is not a replacement for XCTest UI tests or App Store assets—it's a accelerator for agents that need pixels, not a launch or analytics tool. Complexity is intermediate because you need Xcode, simulators, and sane preview definitions on the machine running the skill.
- Builds previews for Xcode projects, Swift Package Manager packages, and standalone Swift files
- Captures preview output for visual analysis by Claude Code and similar agents
- Keywords cover Swift, SwiftUI, simulator, and iOS tooling (v2.0.7, MIT)
- Single-plugin marketplace focused on one preview-build skill
- Homepage and repo: Iron-Ham/XcodePreviews on GitHub

FAQ
Who is Preview Build for?
and small-team SwiftUI developers who use AI coding agents and already maintain #Preview blocks or preview-capable targets in Xcode.
When should I use Preview Build?
Use it while implementing or refactoring SwiftUI screens when you want the agent to inspect rendered previews instead of inferring UI from source alone.
How do I add Preview Build to my agent?
Add the Iron-Ham/XcodePreviews Claude marketplace plugin Preview Build to your Claude Code (or compatible) plugin list and run builds on a Mac with Xcode installed.
