<p>I have created a brand new project in XCode and have the following in my AppDelegate.py file:</p>

<pre><code>from Foundation import *
from AppKit import *

class MyApplicationAppDelegate(NSObject):
    def applicationDidFinishLaunching_(self, sender):
        NSLog("Application did finish launching.")

        statusItem = NSStatusBar.systemStatusBar().statusItemWithLength_(NSVariableStatusItemLength)
        statusItem.setTitle_(u"12%")
        statusItem.setHighlightMode_(TRUE)
        statusItem.setEnabled_(TRUE)
</code></pre>

<p>However, when I launch the application no status bar item shows up. All the other code in main.py and main.m is default.</p>

I had to do this to make it work:
Open MainMenu.xib. Make sure the class of the app delegate is
```
MyApplicationAppDelegate
```
. I'm not sure if you will have to do this, but I did. It was wrong and so the app delegate never got called in the first place.
Add
```
statusItem.retain()
```
because it gets autoreleased right away.
