... And They Shall Know Me By My Speling Errors

Todd Ditchendorf compares Cocoa and Java and C# when it comes to acessing the GUI thread in their respective GUI toolkit. He ranks the readability as Cocoa then Java then C#.

Here is the Cocoa version, is this readable?

//... inside class definition ...

- (void)doStuffOnWorkerThread {
    // ... do worker thread stuff, then...
    id arg = ...
    [self performSelectorOnMainThread:@selector(doStuffOnMainGUIThread:)
                           withObject:arg
                        waitUntilDone:NO];
}

- (void)doStuffOnMainGUIThread:(id)arg {
    // update UI, etc...
}

If you are into brackets, self-referential code, name:value, operators as scope modifiers, and methods that look like e-mail addresses then Cocoa is for you. I prefer something more Groovy...

arg = ...

doInThread = {
   // update UI, etc...
}

SwingUtilities.invokeAndWait doInThread

Even groovier...

arg = ...

SwingUtilities.invokeAndWait {
   // update UI, etc...
}
