NSTableView with Cocoa Bindings

I think Cocoa Bindings is a little bit controversial technology. Some people believe less code means less error, easier to debug, according to the others it is hard to read and understand, it’s black magic. During the years I tried to understand several times with very little luck. Last night I read a brilliant book by Stuart Grimshaw. I highly recommend his book, he wrote a lot of very useful concept about general programming and Swift coding as well.

This tutorial shows a simple Table View. final

Step 1. Create a new Swift project with Storyboard. create

Step 2. Add a new file with a Person class, which conforms KVO.

import Foundation

class Person: NSObject {
    @objc dynamic var firstName: String
    @objc dynamic var lastName: String
    @objc dynamic var mobileNumber: String
    
    init(firstName: String, lastName: String, mobileNumber: String) {
        self.firstName = firstName
        self.lastName = lastName
        self.mobileNumber = mobileNumber
    }
}

Step 3. Create an array in ViewController.swift as data source of the TableView. This will be the last code we need to write.

@objc dynamic var peopleArray: [Person] = [
											Person(firstName: "Ragnar", 
													lastName: "Lothbrok", 
													mobileNumber: "555-1234"),
                                            Person(firstName: "Bjorn", 
                                            		lastName: "Lothbrok", 
                                            		mobileNumber: "555-3412"),
                                            Person(firstName: "Harald", 
                                               		lastName: "Finehair", 
                                               		mobileNumber: "555-4512")]
