11. Beginning AppKit

Written by Sarah Reichelt

In the previous two sections, you learned some basic Swift and built a complete app using SwiftUI. Apple provides two different layout frameworks for building macOS apps and in this section, you’ll use the other one: AppKit.

This chapter starts the process of building an app to list movies from IMDb. By the time you’re finished, you’ll be able to search, sort, filter and edit your movies list.

You’ll start from scratch with a new style of app template and build your interface graphically using a storyboard. Then, you’ll learn how to get data into an AppKit table.

When you’re finished, your app will look like this:

I’m sure you’re excited to proceed, so start Xcode and get ready to code.

Creating an AppKit App

Once you’ve started Xcode, create a new project from the Welcome to Xcode window, or by selecting File ▸ New ▸ Project…. As before, choose macOS ▸ App before clicking Next.

Set the Product Name to MovieTables and leave Team as None or select your own developer team. Enter your reverse domain for the organization identifier — you can make one up, it doesn’t have to be a real domain.

Now for the different setting: Select Storyboard for the interface. Leave language set to Swift and when your options look like this, click Next:

Decide where to save your project and click Create.

Note: It always works best to name your Xcode projects with no spaces and no characters apart from letters and numbers. You can change the app name later, but you’ll avoid Xcode issues if you start like this.

Click the Play button in the toolbar or press Command-R to run the app:

There’s a single empty window and if you click the menus, you’ll see a lot of menu items.

Return to Xcode and look at the starting files:

Your SwiftUI app had Assets.xcassets for images, icons and other graphical assets but the others are new:

• AppDelegate.swift: A delegate is an object that receives events from, and provides information about its parent. AppDelegate is a subclass of NSApplicationDelegate and it handles interactions with the application itself.
• Main.storyboard: This is where you’ll design the user interface. You’ll spend a lot of time in this file as you work through this chapter.
• ViewController.swift: In SwiftUI, you create Views that the app shows in Scenes. In AppKit, you create subclasses of NSViewController. Each view controller has a view that contains the interface. The view controller acts as the middleman between the view and the data models. This is the Model-View-Controller or MVC pattern and is the default pattern for AppKit apps.

What is AppKit?

By this stage, you may be wondering what AppKit is and why you’re using it.

Adding Data

In the SwiftUI app, you built the interface first and then constructed the data model to suit. This time, you’re getting data from an external source so it works best to look at that first and then build the interface around it.

Creating the Data Model

Press Command-N or use the File menu to make a new file. Choose the macOS ▸ Source ▸ Swift File template and click Next. Name the file Movie.swift and click Create.

Converting the JSON

Before you can display the data in a table, you need a method that reads movies.json and converts the JSON into an array of Movie objects.

Storyboarding

There’s been a lot of coding so far with little visual result, but finally you get to the user interface.

Configuring the Window

Start by selecting Window by clicking inside the box labeled Window or by selecting Window Controller Scene ▸ Window Controller ▸ Window in the outline view.

Setting Up the View

Click inside the View Controller box or select View Controller Scene ▸ View Controller ▸ View in the outline view. In the Size inspector, set Width to 800 and Height to 400 to make this view the same size as its containing window.

Inserting a Table View

Press Shift-Command-L or click the + button in the bottom toolbar to open the Library. You’ve used the library before to find SwiftUI views and modifiers. Now it shows AppKit objects instead.

Positioning the View

In SwiftUI, the layout engine works out the optimum size and location, depending on the view type and its contents. With AppKit, you have to explicitly tell the view where to go and what size to be.

The final table has three columns showing the title, year and rating for each movie. The default table comes with two columns, so now you’ll fix that.
