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...

Show icons only in SwiftUI swipe actions on iOS 26

Starting with iOS 26, SwiftUI shows both title and icon in swipe action buttons by default, but the previous icon-only appearance can be restored using the labelStyle() modifier.

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...

Starting with iOS 16.4, we can use the presentationCompactAdaptation(_:) modifier to tell SwiftUI that we prefer popover presentation even in compact size classes.

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...

If we want to take advantage of the new iOS 26 Liquid Glass appearance for sheets that include forms or push views onto a navigation stack in SwiftUI, we have do some extra setup. I've just published a post showing how this can be done: nilcoalescing.com/blog/LiquidG...
