A quick look through the application's bundle shows all the signs of a product still deeply welded to Carbon.
A quick glance through the Info.plist:
- No Principle Class so no NSApplication at launch
- The HIWindowFlushAtFullRefreshRate flag is set indicating at least a few Carbon windows
- Application requires Carbon environment flag is set
There are a few .nib files in the bundle, but all the ones I looked at were Carbon.
Localized strings are still kept in a resource (.rsrc) file! What in the world.
In fact, there are no obvious signs of any Cocoa use at all.
As someone who's day job involves maintaining a Carbon app that "should" be transitioned to Cocoa, I can sympathize. But it is concerning as Apple wastes development time adding features like Genius to a straight Carbon application. Anybody writing new features will know that their work will have a shelf life of about 9 months; and will have to be reimplemented—at least the GUI parts—in Cocoa. And the sooner a Cocoa iTunes comes out, the faster it will become a mature, bug-free product.
