I had a feeling App Store Connect submissions were sometimes really slow so I timed it, and yes: 1m 20s. Of course, there’s the intermediate screen I’ve never used that you need to click through.

If you’re really bored, here’s a recording:

I cleaned up my follow page. It’s now in line with my vision: I post on my own site, and my posts can be followed in various ways.

I’ve been making a lot of updates to the setup behind the scenes, and I want to write more about it at some point. »

Doctor Who series 2 episodes 5 & 6 from 2006, feature an enormous, global technology company that produces tiny wireless headphones called EarPods and has their UK base of operations in — wait for it — Battersea Power Station! Parallel universe indeed. »

Current status: slugifying strings for URLs with Shortcuts. Possibly the most hilariously cumbersome programming tool I’ve used, but kind of satisfying chaining together four actions to do what would be one function call in Swift. »

Ben Brooks on iPad:

Now my troubleshooting time is spent wondering why Apple cannot get rid of the floating text controls UI bar that is in the way 99% of the time, and useful about 3 times a year.

And these controls adjust insets so everything slides around when keyboard focus changes. »

Haven’t seen any news yet on when App Store submissions will open for visionOS. Presumably the Xcode 15.2 RC is what we’re waiting for.

Update: Xcode 15.2 was available 30 mins later. »

Style guides are hard (source)

Screenshot of Apple webpage highlighting the text “Don’t break Apple Vision Pro over two lines.” and further down showing that same text split over two lines.

They’ve done this using CSS white-space: nowrap: Apple Vision Pro — but missed it in some places.

An alternative is to use non-breaking spaces (option + space): Apple Vision Pro — this will work if CSS is removed, such as in my reading app. »

I’m finding the year in review fanfare from so many apps excessive. Apple Books is keen to tell me I read three books in 2023. Maybe I would have read more if I could still use the iOS 15 version of Apple Books. »

Now we’re under time pressure to set up a new (more expensive) Apple silicon Mac on CI. »

Some of my Christmas baking. Not-quite Linzer Augen:

Panettone and biscotti:

Photo of crunchy little fruit and nut filled bread slices, and a tall round bread/cake dusted with icing sugar.

Cheese-stuffed bread balls with sweet peppers:

Pro tip: to follow Apple’s style guide about not splitting Apple Vision Pro onto multiple lines, create a text replacement that already includes non-breaking spaces.

Graphics contexts created by UIGraphicsImageRenderer are somehow invalid for reading the width and height. Read more »

I’ve been at PSPDFKit long enough to have learned C++ and forgotten it again. »

14 January 2024

Is anyone else putting commas before argument labels in Package.swift, like this, for nicer diffs and so lines can be commented out easily? Read more »

Spaces are filling up for our first NSLondon event of the year, which is at Trainline next Tuesday. »

18 January 2024

Speaking of Trainline, Google are scamming them here selling ads for their own service doing what I’m already doing. 🇮🇹

Screenshot showing looking at tickets from Bari Centrale to Rimini on the Trainline website, with an ad for Trainline with the text “Trains all over Europe? Totally.” »

Has anyone switched an app to year-based version numbers and regretted it? I’m thinking <year><dot><incrementing number>, which seems to be what Overcast and Castro use. Our PDF Viewer is currently on 6.5.7, which seems unwieldy, and we release often so it never has ‘major’ releases. »

We had a report of a fun bug today with a situation the PDF reference doesn’t specify how to handle. Read more »

Today marks four years since I went on a plane. I wrote about my journey from flying around the world as a digital nomad to not flying at all. Read more »

Submitted PDF Viewer for Apple Vision Pro for app review, complete with upscaled and cropped screenshots. Hopefully it works!

Just in case anyone happens to have an Apple Vision Pro, you can now download PDF Viewer from TestFlight!

My first ski day of the season. Went on an avalanche safely course, which had a good mix of different aspects. There’s so much software to help, such as Avalanche.report, Fatmap, Skitourenguru and Outdooractive. »

It’s great when you ask ChatGPT to write some code, then immediately ask it what problems there are with that code, and it correctly identifies that temporary files aren’t being cleaned up, loading large files all at once might use too much memory etc. »

As a software engineering manager, when I see the word “continue” in a team member’s plan for today message (a sort of lightweight, async stand-up we do), it’s a hint that a fresh perspective might help move things forward, so I should look into the progress. »

2 February 2024

And… PDF Viewer for Apple Vision Pro is out. The highlights are in the announcement post.

I’ve had a 5k LG UltraFine display since 2016, and today was the first time I noticed any image ghosting on it. Only noticeable on a ~27% grey background, which doesn’t normally occur because I use light mode. »

11 February 2024

Wish for iOS 18 lock screen on iPad: separate rows of text to show the date, charging status, and “Face is too far away”. This seems like something widgets/customisation should have solved, but no. »

Snowy mountain photo with a ski run in the foreground, blue sky, and clouds between the peaks further away.

Sölden today. Decent snow at glacier level only. Overcrowded (not pictured).

I was amused by the announcement about the “zero zero seven elements” experience. »

19 February 2024

Recently with the iPad dock, if I flick an app icon up with the mouse (happens accidentally), the drag gets cancelled, then a wiggling duplicate app icon remains while the dock is visible (even when not in edit mode) until restarting the iPad.

Not being forced to use Apple’s terrible user rating and review system seems like a really nice perk of alternative app marketplaces in the EU. »

Trying out a new Stage Manager setup on iPad for better focus.

Before: One stage to rule them all: Mail, OmniFocus, Bear and Safari with Slack as a pinned tab.

New: Inbox space with Mail and a Safari window just for Slack; execution space with OmniFocus, Bear and anything else in Safari. »

Hmm, this is messy with links opening in the inbox stage. I might need to make a Slack single-site browser app to prevent this. »

Lesson learned: While it’s fine to revoke a certificate used for app distribution at any time (you just make a new certificate), the same is not true when using the certificate to sign XCFrameworks, where revocation leads to not being able to build with already released versions. »
