I just released WhaleDeck 3, which makes Docker management and monitoring a joy.

In case you aren’t familiar, Docker enables you to run apps and services in isolated containers on your computer or server.

Interesting. Simply displaying this table seems to be extremely expensive on the main actor and it prevents the chart from updating immediately, even though fetching the data only takes a few milliseconds. Is Table really that costly to render or am I missing something?

Querying one million rows with 12 properties each fully locally using SQLite. I think this is pretty decent performance, especially considering that such a large dataset is only expected for a very small user base. The UI is powered by SwiftUI and Swift Charts.

Ugh. What a tough decision: supporting cross-device sync via CloudKit requires all primary keys to be UUIDs. My tests showed inserts up to 60% slower and queries around 30% slower with a million rows. But not having the option for sync would suck too.

What a rough journey. I originally started this project with SwiftData, but reading got painfully slow with just a few 100k entries. Switching to Core Data solved this, but insert performance was still similar to SwiftData. I am now using SQLiteData and it's great.

With Liquid Glass, optimizing your widgets for different rendering modes is something worth looking into. Large content can appear odd if not handled correctly. @Environment(\.widgetRenderingMode) lets you create custom designs for each mode.

I played a few minutes with the Sora 2 app and generated some Xcode AI slop. What kind of dystopian world are we heading toward if we spend our days consuming this junk?

Just a quick TIL: If you're wondering why your XCUITest isn't showing up in the simulator, either enable "Show Parallel Testing Devices" to reveal the hidden simulator, or disable parallelization in your test plan to use the main simulator.

Why do people in 2025 still fill out contact forms without real contact information? What do they expect when they enter nonsense into the fields? Sure, the form works, but I can’t tell ya 🫨🫩

TIL the hard way that the Keychain on macOS behaves quite differently when saving credentials locally compared to iOS/Mac Catalyst 🫨 Thanks to this random dude who wrote the article, it saved my Sunday.

May today be the day I finally finish the iOS 26 update for WhaleDeck. I’ve already spent almost 140 hours on it and the todo list keeps growing. At least the tasks are getting smaller 🥳

Running tasks is now smoother in WhaleDeck. The full-screen overlay is gone, replaced by a small indicator that disappears after a few seconds or stays if something goes wrong.

Is there a way in SwiftUI to open a new window not in fullscreen on iPadOS? By default, when the main app is in fullscreen, openWindow also opens the new window in fullscreen. However, I’d like it to open as an overlay, similar to how Mail and Notes handle it.

Just a quick service reminder: Don’t forget to add your OpenIntents to your app’s target. Otherwise, you’ll look just as stupid as I did debugging why the intent wouldn’t work in the Shortcuts app.

Am I missing something, or are full-screen screenshots in the App Store broken on both iOS 18 and 26? Just look at how squashed the 18:32 looks, and those logs seem really off. It’s even worse on 26 than on 18.

I'm still working hard on this update, but I’m already very proud of it. Much of the functionality is now deeply and naturally integrated into toolbars, context menus, swipe actions and shortcuts, allowing users to access it anytime and anywhere.

I've spent the past three weeks completely redesigning WhaleDeck for iPhone, iPad, and Mac. It was an incredible amount of work, but I think it's now much easier to use, especially in a professional context.

Still lots more work left to do before the release.

What's your go-to way to group larger info on macOS with #SwiftUI? On iOS/iPadOS I love how List and Sections look, but on macOS they're hard to tell apart.
Any better ideas than ditching List and overusing GroupBox / RoundedRectangle?
