WWDC 2022 Wishlist

Apple has announced that their 2022 World Wide Developers Conference will again be an online event from June 7 to 11. The poster shows a very dark Swift logo in a coloured circle. While I have long since given up trying the read the tea leaves of Apple’s graphics to work out what they will announce, I always enjoy speculating. But this year, I thought that instead of trying to guess what Apple will have for us, I’d think about what I would like them to announce, with my main focus being the Mac.

Not much action on the site lately as I work on other projects. But I have finally got around to adding a search option to the site.

The Apple DTK Gamble

So I gambled…

I hoped Apple would do the right thing by developers who paid for access to the Developer Transition Kit (DTK) to get the first Apple Silicon Macs, but I was wrong and I lost.

UPDATE - 6 Feb 2020: Apple has responded to feedback from me and other disgruntled developers and so I didn’t lose as much as I thought. Apple is now giving US $500 credit, which is what developers in the US paid for the DTK, and they are extending the time limit to the end of the year. I am quite certain they will release a desktop M1 Mac before then, so I will get credit for most of the cost of the DTK (after exchange rate losses) and I will be able to use the credit towards a Mac that I want.

Thanks Apple for listening and reacting.

SwifUI Mac Menus

With the option to create apps using the SwiftUI App life cycle, we get a new way to set up menus in Mac apps. This post will explore some of the ways to do this as well as look at the default menu groups that Apple gives us.

SwiftUI Data Flow

SwiftUI gives us a completely new way to lay out out user interfaces, in a declarative and responsive way. Your data dictates what is displayed. But this leads to a new problem - how should the data models be constructed and how can they be passed around between the various views that make up your app?

In this post, I intend to discuss the possibilities with examples.

Update - January 2021: I think the information in this post is still all valid except for one change. When you are initializing an ObservableObject, you should use @StateObject instead of @ObservedObject. Your views can receive objects that are owned by other views as @ObservedObject or @EnvironmentObject but the owner of the data should always create the data object with @StateObject.

Crossfix

I have just released Crossfix and Crossfix Lite for iPhone. They are both the same anagram assistant solver for crosswords, particularly cryptic crosswords. The Lite version is free but limits you to three solves per day. The full version is unlimited with no ads, no recurring subscriptions and works with family sharing.

SwiftUI for Mac on Big Sur

In December 2019, I wrote a series of articles about using SwiftUI to build a Mac app. At WWDC 2020, Apple announced macOS 11 Big Sur along with Xcode 12 and a heap of new features for SwiftUI, so I decided to try creating my test app again and seeing how much had changed.

SwiftUI Snapshot Testing

Snapshot testing is a technique that has been very popular in the web development world and it seems like a great way to test SwiftUI user interfaces. I read about snapshot tests in a recent blog post and was intrigued, but I had some difficulty getting it to work, so when I finally succeeded, I decided to share my experiences in the hope that others will find them useful.

Name This App

My current work in progress is an iPhone app designed to make it easier to solve crossword anagrams by emulating and improving upon an ability that was there when we used to do crosswords on paper, but is missing for digital crosswords.

But I cannot think of a clever name for the app, so please read the story and contact me with your name suggestions or if you would like to test the pre-release version of this app.
