Hi,

http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/NSTrackingArea_class/Reference/Reference.html

Looks like the initializer is:

– initWithRect:options:owner:userInfo:

Try something like:

tc = NSTrackingArea.alloc.initWithRect(self.bounds, options:(NSTrackingMouseEnteredAndExited | NSTrackingActiveAlways), owner:self, userInfo:nil)
