Two iPhone screenshots of a recipe view in Breve app on iOS 26 and 26.1

I noticed that on iOS 26.1 there are some small improvements to the Liquid Glass tab bar: the selected tab color looks less saturated, making it more readable on top of colorful backgrounds, and the edge effect is stronger.

Here is @brevecoffeeapp.bsky.social on iOS 26 and 26.1:

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.

Two iPhones side by side showing coffee recipe screens from the Breve app. The left screen displays a watercolor illustration of a macchiato in a pastel cup, while the right shows a latte macchiato in a tall glass. Both feature ingredient lists and brewing steps over soft gradient backgrounds in warm and cool tones.

Macchiato or Latte Macchiato? Bold espresso softened by a touch of milk, or creamy milk marked by espresso?

Two iPhone screens of the Breve Coffee App showing coffee brewing steps and a timer displayed above the tab bar, next to a SwiftUI code snippet demonstrating the use of .safeAreaBar(edge: .bottom) with a CountdownTimer view and an interactive glass effect

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().

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.

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...

Avoiding text truncation in SwiftUI with Dynamic Type Prevent unnecessary text truncation at larger text sizes with the fixedSize(horizontal:vertical:) modifier, forcing the text to expand vertically as needed.

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...

Lime motor has been used for centuries to protect wood from termites the lime will stay extremely corrosive for hundreds of years. The lime reacts with the outer layer of wood and forms a form of limestone that the termites do not like to eat through.

Best would be to do an onsite test with some sensors within the sample wall as the local conditions are hard to replicate in a lab.

The issue with metal framing is that the lime will react with it.

The lime should protect the wood very well even in a tropical env as long as you fully envelop it.

from what I have read and been told one is supposed to coat metal with a sealant. The high alkaline content of the binder can react with the metal.

Best is to use untreated wood, treated wood will outgas through the hemp into your home as the hemp is intentionally vapor permeable.

no the hempcrete is made from the woody stems.

In many parts of the world until recently it was legal very complex to get a permit to grow due to the relationship Cannabis. For a long time the US imposed very strict trade embargoes on nations that permitted its growth and it took a long time to unwind these.
