studio by secondthumb
a swift studio for iphone and ipad. write swiftui, run it on the device, and get help from an agent when you want it. built on the wren runtime, no mac needed.
what it does
live swiftui
wren interprets swift source and builds real swiftui from it: 66 views, 176 modifiers, gestures, and animation. state persists between renders, so buttons, timers, and bindings keep working while you edit.
agents
connect a claude pro or max subscription, an api key from anthropic, openai, or openrouter, or a mac running claude code or codex. the agent can write, explain, fix, or improve code, and each change it applies can be undone.
projects
projects hold multiple swift files plus images, fonts, audio, and data. there are over 25 templates covering games, utilities, forms, charts, and animation if you'd rather not start from a blank file.
design systems
attach color, typography, and spacing tokens, written guidelines, and moodboards to a project. the agent receives them with every request, so generated code follows your design.
export
export a single .swift file or a complete swift package with resources included. packages open in xcode and can come back into studio without losing anything.
studio apps
a catalog of complete apps you can download and open as editable projects, including chasma, a tactical card game built entirely in studio.
the editor
syntax highlighting, line numbers, undo and redo, a keyboard row for swift punctuation, console output, and a full-screen mode for running projects.
learning
interactive swift tutorials, a snippet browser, and working example apps you can open and read. the agent can explain any code you point it at.
