Caterpillar window

While it would be lovely to spend all of this summer working on iOS 26 redesigns and features, the realities of the business are such that I'll need to ship several updates over the summer.

Started working on one of these updates today and it is super weird. It is like I’m working in the past, with knowledge of the future. I’m tweaking my iOS 18 designs so that they are more “Liquid Glass Compatible" and will be easier to adapt later this summer when the time comes for the re-design.

Do yourself a favor and turn on Debug > ”Slow Animations” in an iOS 26 simulator and then bounce around within an app. It really lets you get a sense of the fun merging effects they are doing with Toolbars and generally how so much "life" the system is imbued with.

The way the glass droplets combine and separate is gorgeous.

I wish the UITabAccessory could be turned into an inline button, instead of sitting above the tab bar.

@steipete This looks great, thanks for sharing! When I get a chance I’ll see if any of the prompts I’ve built up are worth contributing

Just a reminder for anyone feeling overwhelmed because they've bookmarked 100 session videos and have a backlog of podcasts and articles to read.

iOS 26 isn't shipping until September.

You've got time. Absorb at your own pace #WWDC25 #iosdev

As a data nerd, the expanded metrics and improved UI of App Store Connect is going to be sweet 🥳 #wwdc25 #iosdev

Decided to check out the reaction to liquid glass on Twitter. On the one hand, I feel bad for all the Apple designers inundated with mean replies. On the other hand, why are you still on Twitter?

If your project crashes in #Xcode26 upon opening, the official fix is to find the "UserInterfaceState.xcuserstate" file and delete it (as stated in the release notes).

Right-click your ".xcodeproj", choose "Show Package Contents". Do the same for "project.xcworkspace". Now delete the entire "xcuserdata" folder which contains the incompatible ".xcuserstate" file. Done! ✅

What a delightful log message:

NSLayoutConstraint constant is not finite! That's illegal.

🤣 #iosdev

Is there a safe/reliable way to install MacOS 26 on an external SSD nowadays (using an Apple Silicone mac)? Has anyone done this? #WWDC25 #iosdev #macos

So Moderation without any changes looks ok-ish on iOS 26 #iOS26 #iosdev #WWDC25

Hah what a delightful detail. Apple computes chromatic aberration at the edge of the Lock Screen glass

@kharrison It looks like it - just installed is on my laptop. Time to upgrade to the beta I guess 🤷‍♂️

@kharrison They said it is in beta 1 with ChatGPT support apparently

It looks like Apple *nailed* the API for its on-device LLM. It looks easy, powerful, and flexible. Virtually every app is going to want to add this stuff this year
