A place to work with Swift

iSwift brings together a browser playground, practical code recipes, and resources for moving from Objective-C to Swift.

Small examples, clear explanations

The cookbook focuses on useful patterns you can understand and adapt. Each recipe includes source code, an explanation, and caveats that matter in a real project.

Historical iSwift links

The playground and known cookbook addresses have been preserved in this rebuild. An old snippet link may not reproduce content from databases that are no longer available.

Execution environment

The playground now embeds OneCompiler’s Swift editor. Swift source is compiled and executed by OneCompiler, so iSwift no longer depends on its previous Wandbox or JDoodle runner or on a paid compiler API key.

Independent resource

iSwift is an independent resource and is not affiliated with Apple, the Swift project, or OneCompiler. Visit Swift.org for official language documentation and downloads.
