LYKOV STUDIO
Swift code runner for iPhone and iPad
SwiftMate turns your iPhone or iPad into a focused Swift scratchpad. Write code with a purpose-built editor, run compact snippets, read console output and compiler diagnostics, organize files, import code from images, and inspect AST results when you need more than a quick print statement.
Open SwiftMate when an idea is too small for a full Xcode project but still deserves a real compiler result. The editor gives you syntax highlighting, line numbers, search, smart pairs, automatic indentation, and local completion suggestions drawn from Swift keywords, snippets, common symbols, and the current file.
Tap Run to send the snippet to the configured HTTPS Swift runner. The console brings back output, exit status, duration, and compiler diagnostics, so you can change the code and try again without moving the exercise to another device.
SwiftMate works well for algorithms, language exercises, interview practice, Foundation examples, utility functions, and small ideas you want to test while away from a Mac. Keep related snippets as files, duplicate a working example before changing it, and share the result when you want to continue elsewhere.
It is deliberately narrower than a complete Apple app-development environment. That focus makes the app useful for quick feedback, while the clear limits prevent it from pretending to be Xcode on a phone.
Swift files remain local until you choose Run or AST. Those actions require the source and optional input to travel over HTTPS to the configured runner backend, where Swift is compiled or inspected and a result is returned to the app.
SwiftMate excludes source code, stdin, stdout, stderr, compiler output, file names, and file contents from its analytics and crash-report parameters. Running and AST inspection still require an internet connection and an available backend.
Do not paste secrets, production credentials, private keys, or confidential source code into any hosted code runner, including SwiftMate.

SwiftMate is a Swift code editor and hosted runner for iPhone and iPad. Use it to write short Swift programs, organize files, run snippets, read console output and compiler diagnostics, and inspect code structure without opening a Mac for every small experiment. Learn more about SwiftMate.
Yes. Write or import a Swift snippet, tap Run, and SwiftMate sends the code over HTTPS to its configured Swift runner. The result returns to the in-app console with output, exit status, duration, and diagnostics when available. Learn more about running Swift code.
Files stay local while you edit and organize them. When you choose Run or AST, the source and optional input must be sent to the runner backend for compilation or inspection. Source code and console contents are excluded from product analytics and crash-report parameters. Learn more in the SwiftMate FAQ.
No. SwiftMate is built for snippets, exercises, algorithms, and fast experiments. It does not build or sign complete iOS apps, run an iOS Simulator, show live SwiftUI previews, archive projects, or submit apps to App Store Connect. Compare SwiftMate and Swift Playgrounds.
Yes. SwiftMate supports iPad with a wider editor layout, file navigation, completion suggestions, console output, and the same core snippet workflow available on iPhone. Learn more about SwiftMate on iPad.
Premium can unlock broader run access, image-to-code import, custom snippets, pro editor fonts, additional Swift versions, and AST inspection. Exact products, prices, quotas, and availability can vary, so check the current App Store offer before purchasing. Learn more in the SwiftMate FAQ.
