Objective-C can't run inline (yet)

Some languages need a real compiler or runtime that doesn't fit in a browser. But you can run Objective-C instantly on these free platforms:

Sample Objective-C code:

Objective-C example
// Objective-C method call
[NSString stringWithFormat:
    @"Hello, %@", userName];

[button addTarget:self
    action:@selector(buttonTapped:)
    forControlEvents:UIControlEventTouchUpInside];

Try these Objective-C examples

A note on this playground

Code runs in your browser using open-source engines (Pyodide for Python, native JS for JavaScript, AlaSQL for SQL). Nothing is sent to OneCity's servers. No accounts, no tracking. If you save your work, copy-paste it somewhere else — refreshing the page resets the editor.
