The Apple Maps app features something that looks like a vertical toolbar where they’ve stacked two grouped buttons on top of each other using a Liquid Glass effect. In this post, you’ll learn how you can make use of a GlassEffectContainer and the glassEffectUnion view modifier to achieve this effect.

Building custom UI with Liquid Glass is easier than you think! Learn how you can leverage animations, the glassEffect view modifier, and a GlassEffectContainer to achieve a fun look and feel that will feel right at home on iOS 26!

Liquid Glass drastically changes how you app looks and feels when you’ve used default system components in your UI. In this post we look at how TabView changes with Liquid Glass, and how this forces us to rethink aspects of how certain interactions in our apps should work.

SwiftUI offers several approaches to building lists of content. You can use a VStack if your list consists of a bunch of elements that should be placed on top of each other. Or you can use a LazyVStack if your list is really long. And in other cases, a List might make more sense. In […]

A key skill for every app developer is being able to profile your app’s performance. Your app might look great on the surface, but if it doesn’t perform well, it’s going to feel off—sometimes subtly, sometimes very noticeably. Beautiful animations, slick interactions, and large data sets all fall flat if the app feels sluggish or […]

With iOS 18, we have the possibility to create mesh gradients. Mesh gradients are a really nice way to create very cool UI effects. In this post, we’re going to explore exactly what mesh gradients are, how we can use them, and how we can even animate them to look really cool. We’ll start off […]

Over the years, Apple has been putting tons of work into the SF Symbols catalog. With SF Symbols, we’re able to leverage built-in iconography that will look familiar to users while also fitting into the Apple ecosystem very nicely. The fact that there’s thousands of symbols to choose from makes it a highly flexible and […]

Environment values are a convenient way to pass data down a deep view hierarchy. We can add values to the environment ourselves, but the syntax is clunky and verbose. In this post you’ll learn about the built-in @Entry macro which makes adding new values a breeze.

Xcode 16 and iOS 18 come with a feature that allows us to build elaborate preview environments using a new PreviewModifier protocol. This protocol allows us to define objects that can create a single context or environment that’s cached and used across your SwiftUI previews. This is useful because it means that you could, for […]

SwiftUI in iOS 18 and macOS 15 has gained a new trick; it can mix colors. This means that it’s now possible to take a color and modify it by applying another color to it using a provided percentage. The video below shows how this works: Notice how the large rectangle updates its color to […]
