SwiftUI makes it easy to show a “no results” state for search with ContentUnavailableView.search. And it even automatically includes the search text in the message, as long as it’s used within the scope of the searchable() modifier.

On iOS 26 we have a new `close` button role in SwiftUI to dismiss a view without losing the user's progress, unlike a cancel action. A convenient way to add a dismiss button for modals without the need to define a custom button label!

In the first version of @brevecoffeeapp.bsky.social I placed timers in the tab view's bottom accessory, but it broke in iOS 26.1 beta. In the latest release, I switched to a custom view with an interactive glass effect. To keep it always visible above the tabs, I used safeAreaBar().

I noticed that on iOS 26, the default swipe action appearance changed to show both an icon and a title instead of just the icon. If we want to restore the previous icon-only look, we can use the labelStyle() modifier in SwiftUI: nilcoalescing.com/blog/ShowIco...

In SwiftUI, the popover() modifier shows a popover on iPad but turns into a sheet on iPhone by default. To prefer popover presentation even in compact size classes, we can apply presentationCompactAdaptation(_:) inside the popover's content: nilcoalescing.com/blog/Popover...

When testing Dynamic Type support in @brevecoffeeapp.bsky.social I noticed that text would get truncated at larger text sizes for no real reason. I had to apply fixedSize(horizontal:vertical:) as a workaround to force the text to wrap instead: nilcoalescing.com/blog/Avoidin...
