I am excited to see that Castro is in good hands again.

Congratulations to @danielpunkass on the release his crossword-solving app Black Ink for iOS..

A 30-day streak.

NSHappyHour is at the Lobster Shanty in Salem, MA at 6:30 PM tonight. New folks are always welcome. Thanks to @whitedonkey@mastodon.social for organizing.

I made an early beta version of Unread for macOS available. Details at: www.goldenhillsoftware.com/2024/01/e…

Unread is an RSS reader with beautiful typography, great handling of articles from summary-only feeds, and a variety of color themes.

I like @incanus@mastodon.social’s idea of Repurposing Hugo as a wiki.

I have a bunch of loose markdown files in a version-controlled folder that I consider my “company wiki”. Making it navigable with a web browser and letting documents link to each other would be a significant improvement.

CocoaHeads Boston will meet Thursday evening via Zoom at 7:00 PM Boston time. New participants and participants from outside the Boston area are always welcome.

Congratulations to the winners and runners-up of MacStories Selects awards.

A huge new feature for MarsEdit: Mastodon support. Congratulations to @danielpunkass.

Happy Thanksgiving!

I am now posting to my blog, and automatically cross-posting to Mastodon. The best way to follow or reach me via Mastodon (or Mastodon-compatible) service is @johnbrayton@iosdev.space. You can also follow my posts via my blog and its RSS feed.

I just had a new furnace and water heater installed. The old furnace was 29 years old, the old water heater was 15 years old. I am ready for winter. (Or at least my house is.)

I recently implemented a search suggestions menu on macOS for Unread.

Even though Safari, Mail, and Finder implement search suggestion menus, there is no standard AppKit mechanism for providing them in AppKit. Popping up an NSMenu does not work because the search field cannot receive keystrokes while the menu is displayed.

Interestingly there is a good mechanism for providing search suggestion menus in SwiftUI, but incorporating that mechanism into an AppKit-based application looks much more difficult than just using an NSHostingView.

I ended up starting with a CustomMenus sample project. This 2018 project by Doug Stein is a Swift port of Apple Objective-C sample code from 2012.

With that as a base, I updated it to support things like dark mode. I also made it a little more focused on search suggestion menus, as opposed to custom menus in general.

The result is a sample project on GitHub. I hope you find it useful.

Thank you to:

• Doug Stein for his work to modernize this code in 2018.
• Lucas Derraugh, Daniel Jalkut, Gui Rambo, Christian Tietze, and Nate Weaver for helping me with this in the AppKit Abusers Slack.
• Apple for the original CustomMenus sample code sample code.

We have a great agenda for this evening’s CocoaHeads Boston meeting via Zoom. Conall McCabe will give a presentation pertaining to Core Motion, axes of device orientation, and associated data structures.

I helped my city perform a recount yesterday. It is fun to participate in the process.

My glass shower door (which has probably been in place for 29 years) spontaneously shattered earlier today. No one was anywhere near it when this happened.

Tonight’s online CocoaHeads meeting will include a presentation on Skip, an Xcode plugin that transpiles native SwiftUI iOS apps into Android apps using Jetpack Compose and Kotlin. New participants and participants from outside the Boston area are always welcome.

I was also a precinct clerk, but we don’t get stickers for that. 🤣

We had a preliminary election for mayor, city council, and school committee in my city today. This is a big one. Our mayor of 20 years is retiring, and it’s the first city election since deciding to have ward-specific city councilors and school committee members.

Hilariously we (probably) have 3 more elections between now and the end of March.

I filed an FB a few days ago regarding the need for an API that does not exist on macOS. Apple replied with “We believe the reported problem has been fixed. Please verify that the issue does not reproduce on macOS 14 beta 7…” 🤦‍♂️

Chime is a polished text editor for the Mac with support for several programming languages and an extension API. Now @mattiem@mastodon.social is generously making the app free and releasing the source code.

A fourth indictment. I am starting to suspect Trump might be guilty of some of the crimes we watched him commit on TV. ⚖️

CocoaHeads Boston will meet in person next Tuesday, August 22, at Cambridge Brewing Company. New participants are always welcome. Please RSVP on Meetup if you expect to join us so that we can make an educated guess on the reservation size.

Toolbar images based on SF Symbols are vertically stretched when displayed on a 1x display. I filed this as FB12928137, but wanted to let other developers know. This is tricky because the effect is subtle and because developers without a 1x display will not see the issue. I worked around it by exporting the SF Symbols as 37-point images and putting them in PDFs in the asset catalog. I made each image 55x55, and centered the symbol graphic inside it.

I created a sample project with a Settings window with a toolbar. When displayed on a 1x display, images in the toolbar based on SF symbols get vertically stretched.

You can see the effect in the Settings windows of Apple apps, including Apple Mail and Messages.

To reproduce:

1. Start with a Mac that has both a 1x and 2x display. In my case I have an M2 MacBook Pro 16” with two external 1x displays. The two external displays are VX2239 Series Display (21.5-inch, 1920x1080) and K272HUL Display (27-inch, 2560x1440). I also encounter the issue if I only have either one of the two displays attached.

2. Download and run this sample app.

3. Open its Settings window by selecting “Settings…” under the “SwiftUISettingsWindow” menu.

4. Drag the Settings window to the 2x display if it is not there already.

5. Observe that the Speedometer icon is a 40x40 (based on pixels) circle.

6. Drag the Settings window to the 1x display.

Expected result: I would expect the speedometer to remain a circle.

Actual result: The speedometer is a 19x22 oval.

Alternatively:

1. Open Apple Mail, and select “Settings…” under the “Mail” menu.

2. Drag the Settings window to the 2x display, if it is not there already.

3. Observe that the “@” in the Toolbar above “Accounts” looks as expected, and is 41x42 (based on pixels).

4. Drag the Settings window to the 1x display.

Expected result: I would expect the “@” symbol to retain its aspect ratio, with the height being identical to or one pixel taller than the width.

Actual result: The “@” symbol is 20x24. The gear above “General” also looks vertically stretched.

Notes:

1. My sample app uses SwiftUI. I initially saw the issue with an AppKit app using an NSToolbar.

2. My sample app uses the “speedometer” SF Symbol, but the issue is not specific to that SF Symbol.

3. I do not have a Mac without a built-in 2x display, so I cannot determine whether the bug affects a Mac that has 1x displays but no 2x displays.

4. When capturing screenshots for this blog post I ran into a situation where I could not reproduce the issue with Apple Mail immediately. It like seemed the problem had disappeared. Then I reproduced the issue again by ensuring that when I first opened the Mail Settings window, I first opened it on the 2x display and then moved it to the 1x display. Opening on the 2x display does not seem to be required for my sample app though.

Addendum: It later occurred to me that I am assuming 1x is what is triggering the issue. It could just as easily be using any external display (1x or 2x).

Update August 15, 2023: Thanks to Michael Tsai for linking to this from his blog. He adds some comments and links to related information from Mario Guzmán.
