In part 1 of this series, I created a Mac app using SwiftUI.

So far, nearly all the articles I have seen about SwiftUI show it being used for iOS, more particularly for iPhone.

At WWDC 2019, Apple surprised us all by announcing a completely new declarative UI framework called SwiftUI.

I sometimes like to focus on aspects of the Swift language that get less publicity, but that I think are really useful without adding a lot of complexity.

I think I wrote the first version of Pic-a-POD in 2003 and have been updating and maintaining it ever since, but the time has come to shut it down.

Now that most of my Mac apps have been updated to support macOS Mojave's dark mode, it was time to turn my attention to this web site.

Its been a long time since the last update to Time In Words for iOS but after prompting by Apple (update or we will remove it from the App Store), I finally did it.

Dice Pass 1.1 is now available from the Mac App Store.

With the release of iOS 10 and the need to update iOS apps to suit, I have decided it is time to retire some of my lesser-performing apps as it is not worth the effort required to maintain them.

Man Reader has been updated to version 1.6 with the permissions needed for finding all available man pages and a fix for search terms being over-written after a background update.

One of the big debates among Swift developers is when to use structs and when to use classes.

Today I plan to discuss optionals since they were a feature of Swift that I found difficult to grasp at first.

Loops are a fundamental building block of any program.

One of the nice things about Swift is how clean your code looks.

I was driving through the town of Singleton the other day and of course, it got me thinking about using singletons in my apps.

Do not use !.

While not strictly a part of my Learning Swift series, today I thought I would discuss some of the ways to configure and use Xcode to be a more productive and comfortable programmer. 1.

The first thing to do is to download the latest version of Apple's Swift Programming Language book from the iBooks Store.

Firstly, I can give you the technical answer, as published by Apple: Swift is a new programming language for iOS, OS X, watchOS, and tvOS apps that builds on the best of C and Objective-C, without the constraints of C compatibility.
