Here it is! What's New in UIKit in iOS 26.
This was a pretty mammoth undertaking, and it shows – a whopping 64 minute read!
I'll be keeping this article up to date over the beta cycle. Possibly littered with errors. Shout at me if I've made any stupid mistakes.

I had to _slightly_ change my approach, adjusting the top contentInset instead of layoutMargins for the header inset, but this was largely plug and play.
I also added fractional content offset logic so that when the bounds of the scroll view changes, the content offset adapts to ensure the scroll view is roughly scrolled to the same position.
This feels tone-deaf from Ternus. Apple’s software quality has taken a nose dive in recent years. SpringBoard is riddled with UI bugs and glitches on their $2000 foldable — a device which should set the standard for its product category.
The last thing the SWE org needs to do is “speed up”.

This is a simple UIScrollView subclass, that overrides layoutSubviews to update the layoutMargins depending on a few factors:
1. The preferred header placement (resolved from the traitCollection's verticalBarEdge and horizontalSizeClass.
2. The vertical division reserved region's width and isActive status.
3. The trait collection's layoutDirection, either rightToLeft or anything else.

As a result of the above, it works just like any other UIScrollView, the API client can anchor content to the layoutMarginsGuide, frameLayoutGuide, or contentLayoutGuide, optionally vending a headerView and preferredHeaderAspectRatio which may or may not be respected based on the current layout environment.

Has anyone run into, or better yet found a fix for, this SwiftUI bug where NavigationLinks remain disabled despite having an ancestor NavigationStack?
The navigation link seems to become active when the underlying hosting controller's view is reparented, such as when the navigation controller's interactive pop transition begins.
Yes! The screenshot popup 😭 Used to be so easy to copy to clipboard, then paste into Pixelmator or something to pixel peep.
Now I have to routinely clear my desktop of simulator screenshots.
Death by a thousand paper cuts.

Today I am open-sourcing my custom SwiftUI animation sequencing package that I developed to drive the animations in Letters. It can do all sorts of things!

Anyone else seeing this weird, green-ish hue to the background of sheet presentations?
I don't think this is Duo-specific. Seems to affect sheets with glass backgrounds that transition to the system's default, opaque background when the active detent changes?

One thing building for the iPhone Duo has taught me: just use a UINavigationController for ad hoc "toolbar" buttons...
Even if you don't need the functionality of pushing and popping view controllers onto a stack, it's worth the extra LOC for the correct system placement.
A pattern I've enjoyed using is view controller subclasses vending their own child navigation controllers so API clients don't have to worry about wrapping the view controller themselves.
