I can’t be the only one who thinks it’s time Apple revisited the share sheet, right?
The share sheet splits actions across five different sections: share destinations, circular actions, a featured action, and two separate lists of actions. That’s not even counting the top row of contacts.
But what do these sections actually mean? The mental model isn’t clear to me.
I’ve been using and building for iOS for years, and I still fumble when I need a share sheet action.

Just like TestFlight builds show “What to Test” notes on first launch, Apple should offer developers an option to display the “What’s New in This Version” text the first time users open an updated App Store app. This would be helpful for many developers and their users.

My #1 terminal productivity tip:

This makes CMD+T open a new tab in the same working directory, so starting work in a new tab is way faster.

One of the keys on my Logi MX Mechanical Mini is bust. Support offered a replacement, but they can’t match my exact model, layout, or color since it’s discontinued.
This was my first mechanical keyboard and I’ve liked it. But now I’m considering replacing it for one that’s more repairable.
Requirements:
- Compact, ie. no numpad.
- Must support custom keycaps to form a Danish layout.
Any recommendations?

Is it normal for memory to grow over time when a SwiftUI view observes a model with the Observation framework?
In my ~35 LOC app, memory grows with ObservableSettings.isEnabled, but stays stable with NonObservableSettings. See memory usage graphs.

@nprofile…md38 Right! It requires sandboxing to be disabled, so the Mac App Store is a no-go.

2024-12-06 21:12:29 GMT

@nprofile…md38 Hey John! I just listened to the section of the latest ATP where you briefly discuss how Festivitas gets the magnification of the dock.
It's not using a private API. Instead, it's using the Accessibility API to read the frames of every tile in the dock. Based on those frames, I create a CGPath.
Strictly speaking, I don't know the magnification level, and I don't need to know it, but if I did, I could estimate it.

I’ve had this nagging thought: is it time for Apple to dial back their strong focus on privacy, just a tad?
Privacy is important and I respect how seriously they take it. But it feels like they’ve taken it so far that it’s hindering innovation and fall short of modern expectations.
Balance is key.

@nprofile…lv6z @nprofile…wpca It would be a killer feature if Croissant could post videos and downscale and compress them just enough that they could be posted on the various social media.

@npub1u24…32pl You mention looking into visionOS' particle system and RealityKit, so I'm curious to know if you’ve tried displaying the effects in a 3D environment on visionOS? Like, could the confetti be flying towards the user on visionOS?

@npub1u24…32pl Elf or The Santa Clause are great! Spirited on Apple TV+ is also really good.

@npub1sdu…w074 I love the “drawer” in the bottom and I especially love the animation when changing the pattern! 💖

Since moving to Xcode 15 our unit tests have started running incredibly slow. After picking a simulator, xcodebuild hangs for 13 minutes before running the test.
Other times xcodebuild fails with an error sayig ”Unable to connect to co com.apple.instruments.deviceservice.lockdown - timed out after 120 seconds”.
Anyone seeing something similar?

Had to rename my Wi-Fi (for reasons) and decided to just append “(Taylor’s Version)” to the old name. Of course I did.

Anyone who can recommend a coffee shop or pub to work from in London? Looking for places where I’m not weird for sitting with my laptop. Bonus points if it’s near Victoria Station or Leicester Square but that’s not a must.

Really wish Photos’ great search feature was exposed as an action in Shortcuts.

@npub1eee…e209 Do you know if developers will be able to take advantage of the outward facing screen? For example, put some graphics on there when using an app.
