WWDC 2025

Some quick notes from watching the keynote today:

  • Awesome that they’re opening up on the on device model—before today, it felt like they would only do this in very controlled ways.
  • The glass in some elements (like tab bars) looks like way too much (not enough contrast with the background elements), so I’ll bet $5 that the translucency gets turned down over the summer.
  • The “selected” state for tab bar items looks awful.
  • The all-clear look for icons looks over the top but cool.
  • I’m excited that parts of the UI changing based on the device movement/accelerometer is back. Those seemed to go away over time since the iOS 7 days, but I think they’re great little bits of interactivity.
  • I had no idea that typing indicators in group chats weren’t a thing… guess I’m not in that many group chats.
  • Surprised they more deeply integrated ChatGPT with the image styles; I thought they would keep an arm’s distance from integrating more with OpenAI.
  • FaceTime translation is awesome. I’m surprised they didn’t do the translation in the same voice as the speaker. Maybe that would be too creepy or require too much processing power.
  • It seems like the best Liquid Glass UIs are when the text is light over a dark background. Hopefully they improve the readability across the board.
  • The movement under Liquid Glass when content is playing (like video, Apple TV, etc.) makes all the buttons move and it looks distracting to me. I’m curious to see it in practice.
  • Not sure how I feel about the new macOS design, especially the sidebar. Why does it look raised?
  • The macOS toolbar looks a lot better with contrast between the button shapes and the toolbar’s background.
  • Clipboard history on macOS! It’s always been on my to-do list to try a clipboard manager, but now I’ll just wait for Tahoe.
  • Spatial widgets in visionOS are amazing. I had so many app ideas before the hardware was released that were based on physical persistence. Now it seems like this is possible!
  • Wow, they really brought the macOS window traffic light widgets to iPadOS. And now the design changes on macOS makes sense (they’re consistent with each other).
  • Wow, and the menu bar is on iPadOS now? Awesome.
  • lol @ “We’ve expanded our vision for Swift Assist.”
  • I liked the little movie at the end.

Three iOS 26 home screens showing app icons. The first screen displays transparent icons; the second shows dark mode icons, and the third features light mode icons. A blurred wallpaper serves as the background, placing focus on the icons.A visionOS interface floating in a warmly lit living room, showcasing the Image Playground feature of Apple Intelligence. At the center, a generated oil painting–style portrait of a smiling woman is bordered by a glowing frame. Style suggestions such as Disco, Sci-fi, and Sunset appear below. A ChatGPT option is visible in the bottom panel, indicating integration for generating images. The entire UI hovers mid-air, blending with the real-world environment.A macOS 15 (Tahoe) desktop displaying the updated Xcode interface. The screen shows Swift code alongside a live UI preview and a new minimap for navigation. The menu bar and window chrome have rounded corners and translucent effects. The desktop background depicts a clear alpine lake with snow-covered mountains under blue sky.iPadOS 26 interface featuring a new systemwide menu bar at the top with items like File, Edit, and View. The layout mimics macOS-style controls, enhancing productivity workflows. The left sidebar, listing content options, appears to float above the app canvas, casting a subtle shadow. A stylus hovers near the screen, suggesting Apple Pencil interaction, with a softly blurred wallpaper in the background.

Traveling to Chicago for work this week and coming to terms with this chaotic weather. 😅

Chicago forecast shows rain on Sunday with a range of 46 to 69 Fahrenheit, clouds on Monday with 35 to 46, clouds on Tuesday with 32 to 44, rain on Wednesday with 39 to 71, clouds on Thursday with 46 to 60, and clouds in Friday with 41 to 49.

This bit from the most recent Upgrade makes me think that we only have Automator and AppleScript in macOS because the OS team didn’t want Workflow/Shortcuts (which was bought by the Siri team).

Almost certainly we would have neither in macOS if they had been interested in Workflow in 2017.

Reflecting on 100 Days of SwiftUI

Reflecting on my experience with the “100 Days of SwiftUI” course, with tips on how to make the most of it.

Woo hoo! Day 100 is “just” a final exam and I passed (with merit)! Almost hard to believe that I’ve come to the end of my #100DaysOfSwiftUI journey.

A “certificate of merit” presented to “Chasen” for completing 100 Days of SwiftUI. It includes a quote: “Programming is an art. Don’t spend all your time sharpening your pencil when you should be drawing.” Below is Paul Hudson’s signature with “Founder” underneath. The white background features faint dotted patterns and a blue-toned calendar on the left, with the “Hacking with Swift” logo in the upper left.

Day 99 included our last quiz and challenge: add a photo credit over the image, fill in some loading/saving methods for favorites, and add sorting to the resorts list. #100DaysOfSwiftUI

The iOS Simulator displays an iPad with a “Resorts” app open in split view. The left pane lists ski resorts with country flags, names, and run counts. At the top of the list, a sort picker is open, showing options “Default,” “Alphabetical” (selected), and “Country.” In the list, “Deer Valley” is highlighted with a heart icon, showing “103 runs.” The right detail view displays a skier in a red jacket navigating deep snow, with the caption “Photo Credit: Maarten Duineveld” in the lower corner. Below the image, resort details are presented, including “Size: Small,” “Price: $$$,” “Elevation: 2,000m,” and “Snow: 103cm.” A descriptive paragraph highlights Deer Valley’s location in Utah, upscale amenities, and its role in the 2002 Winter Olympics.

For Day 98, we implemented searching resorts, replaced the facility info with icons, added a button for the user to mark favorite resorts, and added a favorite indicator in the Resorts list. #100DaysOfSwiftUI

The iOS Simulator displays an iPad with a “Resorts” app open in split view. The left pane lists resorts, and “Vail Ski Resort” is selected with a heart icon. The right detail view shows the resort’s information. A modal alert labeled “Family” overlays the entire screen and says, “This resort is popular with families” with an OK button.

For Day 97 we started actually building a new project using NavigationSplitView, NavigationLink, and format: .list(type: .and) (for concatenating strings). #100DaysOfSwiftUI

The iOS Simulator displays an iPad app with a split view layout. The left sidebar lists ski resorts with names, flags, and run counts, e.g. Squaw Valley in the U.S. has 270 runs. The detail view on the right shows the text, “Welcome to SnowSeeker!” with a prompt to “select a resort from the left-hand menu; swipe from the left edge to show it.”The iOS Simulator displays the same iPad app, now showing “Deer Valley” selected in the sidebar. The detail view features an image of a skier in red gear on snowy terrain, with stats below: size “Small,” price “$$$,” elevation “2,000m,” and snow “103cm.” A description highlights Deer Valley’s location in Utah, its upscale amenities, and its history as a 2002 Winter Olympics venue. Facilities include “Family, Beginners, and Accommodation.”

Day 96 and we’re looking at iPad-friendly APIs for the first time.

I’ll be honest—I had not tried running any of our previous apps in the iPad simulator, but now I see they were working fine the whole time. Pretty cool!

This screenshot looks absolutely chaotic. 👹 #100DaysOfSwiftUI

The iOS Simulator displays an iPad mini interface with a split view layout. The left pane shows a folder labeled “Primary.” The right pane features a search bar with the term “S” entered, a “Cancel” button, and two results, “Subh” and “Stefanie.” Below, links labeled “Tap for sheet” and “Tap for alert” are above text that reads “Name: Paul Country: England Pets: Luna and Arya.” A black circle appears under this text. The same text is repeated again, but in blue. Additional text at the bottom reads “Welcome! Your high score: 0.” A stepper for the high score (with plus and minus buttons) appears below. A floating keyboard bar shows the suggestion “S,” with options like “She” and a microphone icon.

Day 95 was a full challenge day—build an app from scratch based on some requirements!

The iOS Simulator displays a Dice Roller app showing two dice with six sides each. Results include rolls of 2 and 4, totaling 6. A blue “Roll Dice” button is centered below the results. A log displays the roll history and date.

Day 94 is a review and challenge day! Graphics code can be a doozy because when you get the wrong result, it’s difficult to know what’s actually wrong in the code (or with your math). 😅 I got some help with this one. 😬 #100DaysOfSwiftUI

The iOS Simulator displays a rainbow-colored list of rows labeled Row 0 to Row 14, arranged vertically in a tapered, 3D perspective. Colors shift from orange at the top (with a light opacity) to red at the bottom (at full opacity). Tab bar icons include Swift symbols labeled Day 94 (selected), Day 93, Cover Flow, Images, and More.

Day 93 was a fun walk through of using GeometryReader, including using visualEffect() and scrollTargetBehavior(). #100DaysOfSwiftUI

The iOS Simulator displays fifteen rows labeled Row 0 through Row 14, each in a different color. Each row is angled in 3D space, keeping the center in place but rotating the left or right sides, creating a cascading effect. The bottom tab bar contains icons labeled Day 93 (selected), Cover Flow, Images, Frames, and More.

For Day 92, we started a new project (our second to last!) and learned about how layout, alignment guides, and absolute positioning work within SwiftUI.

I really loved the explainer, starting from How layout works in SwiftUI. #100DaysOfSwiftUI

The iOS Simulator displays a white screen with multiple text elements, including “Hello, World!” inside a red rectangle, “Live long and prosper” in black, and overlapping versions of the phrase in varying alignments. Tab bar icons for “Day 92,” “Alignment,”, and “Custom alignment” appear at the bottom, with Day 92 selected.

Picking #100DaysOfSwiftUI back up, and in the home stretch at Day 91! It was a challenge day with a review quiz and an open-ended prompt to fix a couple minor bugs and add a feature.

The iOS Simulator displays a flashcard with a quiz question reading, “What is Taylor Swift’s birth year,” on a scratched metallic background. A timer at the top shows 91 seconds remaining, with circular buttons for cancel and confirm at the bottom corners.

For Day 90, we made a bunch of accessibility fixes and added a view for creating new cards! #100DaysOfSwiftUI

The iOS Simulator shows a card creation interface with text fields for Prompt and Answer, an Add Card button below, and a Done button at the top.
