IAC on iOS

Check out GCDWebServer. (Via iOS Dev Weekly, which you should subscribe to.)

GCDWebServer is an embeddable and lightweight http server for Mac and iOS. On iOS it runs as a background task — it keeps running even when your app isn’t in the foreground.

Picture this: app X wants to send some data to app Y.

App Y is running GCDWebServer, so app X wraps up the data as JSON and talks to app Y via http. Just as if it were talking to some server on the web, only it’s a local app.

Update 4 pm: Or not. I’m not sure it’s possible, or maybe just not allowed, to keep a network server running when the app is in the background.
