OpenSwift v0.5

OpenSwift v0.5

OpenSwift is a local SwiftUI sketch studio for discussing and iterating on screen layouts. It does not compile or execute Swift and does not replace Xcode previews.

What you can do

• Open a project folder and browse its Swift files in the desktop Studio.
• Edit a Swift file and render an approximate, static phone preview from supported SwiftUI constructs such as VStack, HStack, ZStack, Text, Button, and common layout modifiers.
• Inspect the sketch tree, render output, and unsupported-feature notices; choose from the included iPhone device frames.
• Save edits to the open file. During a .ui-session, Studio limits saves to the session target and explicitly allowed files.
• Use the Python CLI to draw SVG/PNG previews, inspect a sketch as JSON, and create or inspect UI sessions with SHA-256 iteration evidence.
• Run the local web Studio against a project folder.

Downloads

• Windows: OpenSwift-windows-x86_64.exe — NSIS installer.
• Linux: OpenSwift-linux-x86_64.AppImage — portable AppImage.

The preview is approximate: Swift code is parsed as a supported sketch subset. State, bindings, custom view execution, animations, breakpoints, and native Swift runtime behavior are not implemented.
