Last month, I posted about writing my new todo app called To-Day: why I wrote it and how I wrote it. At the time, I mentioned that I had set it up to install updates using Sparkle but there was too much detail to include in the initial post. So here, as promised, is the article about implementing Sparkle.

When I sit down at my computer at the start of a work day, I typically like to plan out the broad outline of my work. This is the three or four major tasks for my day. I don’t want a minute-by-minute plan, just a list of the major items, so that I can check them off as I work, and get to the end of the day without feeling like I’ve forgotten anything.

There are a ton of todo apps and web services available, but they all provide much more than I need. When I factored in how I wanted to learn about writing a Mac menubar app in SwiftUI, the solution was obvious - write my own.

SwiftUI for Mac 2022

In December 2019, I wrote a series of articles about using SwiftUI to build a Mac app. And in July 2020, I re-visited the sample app to apply the new SwiftUI features made available in macOS BigSur. Now that macOS Ventura and Xcode 14 are in beta, it’s time to build the app again while learning how to incorporate the new APIs.

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.

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.
