To test the interactivity, you need to either ‘build and run’ the application or hit the ‘Play’ button in the preview. When you look at this interface in the preview pane, you will see that the contents of the message variable are reflected in the TextField and Text.

The relevant part of the code is: struct ContentView: View. You will see the code in the center pane. This file contains the Swift UI code that sets up the interface. The left column shows a list of files in this project. There are many situations that will stop Xcode from continuously updating the preview and you can click this button to resume. If it does not there should be a “Resume” button at the top of the preview pane (also called “Canvas”) which you can click to make Xcode resume live updating the preview. When you return to Xcode the preview pane on the right should now be active and also display the “Hello World!” text. You can use the controller element in the top right of the toolbar to hide the right most “Inspector” pane as we will not need it.Ĭlick it the “Play” button in the top left to build and run the template code, a window should open which show the place holder text “Hello World!” The window with the new project will have four vertical panes.

That said, when you want to provide text-to-speech functionality in a Swift app, you should probably use the text-to-speech frameworks, rather than sending out a shell command. It also provides instant feedback, so you know whether it is working or not. The say command is a simple and fun stand in for other command line tools. You can test the command by opening the Terminal and entering > say "Hello World" In this post, we will be using the say command to make the Mac speak. You can download Xcode from the Mac App Store or Apple’s developer page.

I have written this post with Xcode 11.2.1 on macOS Catalina 10.15.1.

I believe that learning SwiftUI now will be a good investment into the future. As you will see, SwiftUI does simplify a lot of the work of creating the user interface. Applications built with Swift UI will require 10.15 Catalina and higher. SwiftUI is the new framework from Apple to build user interfaces across platforms.

In this post, I will describe how to build a simple Mac app which runs a shell command using SwiftUI. Xcode and Swift have progressed over the last three years and that old example is mostly useless now. Surprisingly, this post still gets a lot of traffic. A few years ago, I published a post that described how to build a Mac application in Swift that would run a shell command.
