Learn how to enable SwiftUI's ForEach slow-path diagnostic in Xcode, interpret warnings about variable view counts, and address the reported patterns in List and lazy stacks:
SwiftUI now includes CrossFadeNavigationTransition, a built-in cross-fade navigation transition, and AnyNavigationTransition, a type-erased wrapper that allows transitions to be selected dynamically at runtime:

Just got back from our trip to Wales for iOSDevUK! It was lovely to catch up with everyone and learn from so many great talks. I also really enjoyed running my SwiftUI workshop and seeing everyone excited to dig deeper into SwiftUI, with lots of thoughtful questions and discussions 👩💻 A big thank you to the @IOSDEVUK organizers for putting together such a wonderful conference!

Explore every SwiftUI blend mode through focused visuals and practical use cases, and learn how to control which views participate in each operation:
To diagnose performance issues caused by the structure of ForEach content in SwiftUI's List and lazy stacks, we can enable slow-path logging in Xcode. My new post shows how to set it up, interpret the diagnostic messages, and address the reported issues:

Apple is famous for its rounded rectangles, but nested views need corner concentricity.
@natpanferova explores the new ConcentricRectangle shape and containerShape() modifier in iOS 26 to achieve perfectly aligned nested corners in SwiftUI:

Swift Charts are powerful and you might not always realize how much you can do with this. How about a sunburst diagram, as @nilcoalescing explains?
Control which SwiftUI toolbar actions stay visible, move commands into overflow, pin an important item and configure navigation bar minimization with the new iOS 27 APIs:
Learn how alignment guides position views in SwiftUI, how to override a built-in guide, and how to define a custom alignment for views in nested containers:
Sometimes we want a chart’s domain to include a value beyond our data. Rather than setting an explicit domain, we can append it to the values Swift Charts uses to infer one.

Present grouped data as a multi-level donut chart in Swift Charts, where each outer ring reveals a more detailed breakdown and each subgroup aligns with its parent category:
Build an interactive bar chart in Swift Charts that displays detailed annotations when the user is hovering over bar marks:
Another great chart tutorial by @hishnash, this time it's on how to build a sunburst diagram in Swift Charts, with multiple levels of hierarchical data arranged into concentric rings:

Learn how to use matchedGeometryEffect() in SwiftUI to animate a capsule background that highlights the selected option in a custom segmented control:
When a dataset contains many observations, grouping them into broader categories can make patterns easier to see. Learn how to build a sunburst diagram with Swift Charts to show both the groups and the detail within them.

Heading to @IOSDEVUK tomorrow 🤩 It's going to be a long trip from New Zealand to Wales ✈️ Can't wait to see everyone!
Create a chart with the Swift Charts framework to show UV index throughout the day inspired by the iOS Weather app that dims the area up to the current time:
Looking forward to Natalia’s workshop next week @IOSDEVUK 🎉
