Before Xcode went and added Storyboards for OS X apps you could connect an array controller to your document's managed object context by binding the Managed Object Context of the array controller to File's Owner with a Model Key Path of managedObjectContext . With storyboards there is no more File's Owner so where do you get the context from now? Apple's documentation is behind in this area and there aren't any obvious places to bind to in Xcode. Obviously I can just fall back to a non-storyboard route and use the old method, but there must be a new way of doing it. So I have the answer from

I am one of the great unwashed masses of .NET developers keen to try their hands at Mac OS X development. At the moment I am trying to figure out the various elements of Cocoa and getting a bit stuck on Core Data. I noticed most of the documentation and resources available on the Web involve a broad end-to-end tutorial, beginning from models, generating classes, Document-based UI, etc. Not enough seem to be focused on each bit, or at least not enough examples. Can someone please point me in the right direction, be it online material or books, that can give me detailed instruction of various

I'm new to SWIFT programming and am trying to do a simple app to learn to use core data and bind it to display in an app. I've looked at loads of examples but all seem to be old. I am working in XCode 9. I started with a MacOS Cocoa app with Core Data. I have a simple entity called "Workout" with 4 attributes date, seconds, sport and rpe. I then added a Array Controller under the view controller scene. I added a Table view which set the Array Controller as the data source. I've added buttons to add and delete linking to array controllers add and remove methods. I think all I need to do now is

I am working through a Cocoa in Swift book and I am stuck in a chapter on Bindings. The book uses nib files but I want to do everything programmatically (since I am joining a team that does not use nibs). The project is to create a view based table with 2 columns and the content of the table is bound to the arrangedObjects of an array controller. The array controller's content is bound to an array of Employee objects (Employee has 2 properties viz. name and salary). I was able to create the table programmatically like below (one scroll view, one table view, 2 table columns): let tableWidth =

In my header file, I have a property declared @property (strong) NSMutableDictionary *myContents; In my implementation, I have assigned the contents of a plist (which are dictonaries) to the NSMutableDictionary. In my window, I have a NSSearchField that I would like to bind with the Dictionary and that is the problem. I have a few questions and still don't understand after reasearching. (1)Which should I use? NSObjectController, NSDictonaryController, or NSTreeController. (2)How should I bind the controller to the dictionary? Is there a "key" and a "value" that I can bind or do I have to use

I'm coming from the iOS development and I am wondering if there is a way to set up a NSCollectionView programmatically like a UICollectionView in iOS? And add the NSCollectionViewItems in code. Or is the only way to set up a NSCollectionView to use bindings? Thank You! stefOCDP Thanks to @stevesliva for pointing me to this SO answer . I converted it to Swift. This is what I got. I am creating a NSCollectionView in the ViewController: import Cocoa class ViewController: NSViewController { var titles = [String]() var collectionView: NSCollectionView? override func viewDidLoad() { super
