I wrote these words exactly one year ago:

I’m going to try for more “blank” days in the next 12 months. Wish me luck!

My phone dinged earlier this week with a reminder - “Did you have more ‘blank days’”? It took me a second to remember my promise to myself, but as soon as it clicked, I knew I didn’t need to load my GitHub contributions graph to see the answer.

I did not. 😬

I managed to reduce my contributions by a whopping 2%, but the number of “blank days” is about the same. Does this make me a failure? No, it simply makes me terrible at planning.

I set myself a goal, but I didn’t make a plan. I scheduled the reminder after writing Issue 521, but that’s all I did. Yes, I occasionally thought, “Oh, I should plan some time off” during the year, but then got back to the task at hand and … didn’t.

If I approached writing software that way, I’d be in a mess! Can you imagine starting a year-long project and scheduling the date for the first progress meeting to be three days before the deadline? Ridiculous.

How would I tackle it if it were a work project? I’d track my progress and make a plan.

The statutory minimum time off in the UK is 28 days, and there are 8 national holidays, too. That’s 36 days a year. It’s probably not wise to set my goal to be 100% of that from where I am now, so I’ll try for 50%. Pro-rating that for the remainder of this year means I must take 6 days off work before 2023. That seems achievable.

I’ve set monthly reminders to check in and plan time off, and I’m tracking the number of days I have with a widget in my Mac’s notification area. Now all I need is a JIRA account… 😂

Apple’s use of AppKit, Mac Catalyst and SwiftUI in macOS

Alexandre Colucci has been writing posts analysing Apple’s use of various technologies for several years. This time, he looks at macOS and what technologies Apple is using internally. It’s great to see SwiftUI usage increasing so rapidly. Dogfooding is important.

The Lighter Swift Codegen for SQLite3

There’s a lot going on in this post from Helge Heß! First up is a new SQLite code generation tool, usable either as a command line tool, SwiftPM plugin, or as a Mac app. Use it to generate a data access API for your app or as a mechanism to bundle data into a Swift Package. Finally, it can generate code directly using the SQLite API or the new Lighter package.

That’s a big announcement that deserves more than a one-paragraph summary! I’d recommend giving the launch blog post a read.

Unexpected view re-rendering

This is a helpful thread from Luke Redpath. It’s also a good reminder of how helpful _printChanges can be.

It’s a shame that Apple hasn’t documented _printChanges yet. If you’re wondering what it is, Paul Hudson’s article has a good summary.

View Controller Presentation Changes in iOS and iPadOS 16

The visual changes from year to year in iOS may be subtle, but they do exist. Sizes get tweaked and layouts adjusted. Geoff Hackworth looks at what has changed (and what changes were subsequently reverted) in this year’s iOS betas. The most significant changes this year relate to split views, so if you have an iPad app, this is certainly worth a read.

Visualize sorting in Swift Charts

Sure, you can use Swift Charts to build data visualisations, but how about using it to visualise algorithms over time? Mike Mikina takes a detailed and well-produced walkthrough using the framework to visualise sort algorithms.
