Last year, I wrote a 3 part series of articles on using SwiftUI to build a Mac app. I would like to thank everyone who contacted me about this series. It was received very well and revealed that there is still a large amount of interest in programming for the Mac.

Some of the responses I got were pointing out different or better ways to do things, so I am going to list them here, adding to this post as I get new information. The relevant sections in the original posts will have links to the fixes suggested here, but I decided it was easier to list the changes in a separate post, rather than asking people to re-read the whole series looking for modifications.

In part 1 of this series, I created a Mac app using SwiftUI. The app uses a Master-Detail design to list entries in an outline on the left and show details about the selected entry in the detail view on the right. In part 2 I explored using menus, adding all the expected user interface elements and opening secondary windows.

In this third and final part, I want to look at the various ways to present dialogs to the user.

Now it is time to explore some more of the features of a Mac app with SwiftUI.

So far, nearly all the articles I have seen about SwiftUI show it being used for iOS, more particularly for iPhone. But SwiftUI works on all Apple's platforms, and as I am primarily a Mac developer, I decided to try out a Mac app and see what happened.

At WWDC 2019, Apple surprised us all by announcing a completely new declarative UI framework called SwiftUI. Quoting snippets from the Apple announcements, "SwiftUI is an innovative, exceptionally simple way to build user interfaces across all Apple platforms with the power of Swift" and "SwiftUI uses a declarative syntax so you can simply state what your user interface should do." But what does this mean and should we all adopt it now?
