Hi,
I am creating a Desktop issue tracking app using core data and the
NSDocument framework - so yes, the Xcode wizard extended
NSPersistentDocument which provides me with an NSManagedObjectContext.
My question is - if I start working in the app, creating issues for

When using NSPersistentDocument it takes over responsibility for saving the
context. You should not save the context yourself.

Coming from an iOS background, I'm used to seeing (and encapsulating) the
creation of key Core Data components (persistent store, location,
contexts). Everything is pretty explicit and consequently easy to follow.

Rather than a property I've added an optional method to the protocol which then

So you get to go wrap fcntl() in something else it seems.
So, how would I do that, exactly? I suppose I have to pass Objective-C

That's what I ended up doing (setNonblocking(int inFileDescriptor)), but, I
was asking for the sake of learning the language. It would be nice to have
generic replacements for fcntl() and ioctl().
The best replacement would be to have a set of functions which took the Swiss

In Obj-C, I typically subclass NSWindowController and override -init to call

Hi Rick,
According to the latest documentation pack that arrived on Thursday, Swift has:
convenience init(windowNibName windowNibName: String,
owner owner: AnyObject)
So just use this. Like C++, Swift has overloaded method names, so 'init' can
take various parameter combinations.
I realize, in this case, I should be loading in loadWindow(), but it still
seems problematic.
