In iOS 8, I would (in a view controller):

Let's take the CustomStringConvertible protocol, for example.
You can use this to allow your class to "display" itself in a human-friendly

In ObjC, I can have a class implement the description message so I can do:
MyClass *myObj = [[MyClass alloc] init];
NSLog("%@", myObj);
and it will be as if I did:
NSString *aDesc = [myObj description];
NSLog("%@", aDesc);
What's the Swift equivalent?

Sounds like you're inadvertently depending on the order of loading somehow. Are
you setting up all your bindings in awakeFromNib:? Or do you have any bindings
(set in IB) which refer to something the controller object may have to load
first? Just a thought.

Hi,
I have a need for a complex data-entry form (window). Some fields are
supposed to only accept alpha characters (upper or lower), some are supposed to
only take integers, others to only take floats (but no negative values
allowed). Is there a general way of validating the contents of a fiel
Thanks!

Okay, I'm having a tizzy here. Most of the '...learn MacOS X...' programming
books gloss over the nitty-gritty of actually creating and displaying various
windows, either assuming they're going to be document windows (as part of a
document-based app), or they're just there as part of an example
I would check 2 things:
1) Is there anything in the view controller that's maintaining a persistent
boolean state that toggles each time its awakeFromNib is called?
2) Does it do the same thing when you deploy to an actual iPad?

Oops, my typo: of course I meant to type
'AVPlayerDemoPlaybackViewControllerRateObservationContext'... a 'N' got in
there somehow! :)
