What kind of app redesign is required to support Liquid Glass?

To support Liquid Glass in your app, a redesign is required that focuses on integrating this new material into your user interface. Here are the key steps and considerations for redesigning your app to support Liquid Glass:

1. Recompile with Xcode 26: Start by building your app with Xcode 26. This will automatically update many of the standard controls and views to the new design with Liquid Glass.

2. Audit Your App: Go through your app screen by screen to identify which views stand out and could benefit from the Liquid Glass design. Pay special attention to custom controls and decide if standard controls might be a better fit.

3. Use System Views and Controls: Where possible, use system views and controls to ensure the best experience with Liquid Glass. This includes using updated components like Tab Views, Navigation Split Views, and toolbars that automatically adopt the new design.

4. Custom Views and Controls: For custom elements, create a UI Visual Effect view or an NS Glass Effect view to apply the Liquid Glass material. Customize the appearance using properties like corner radius and tint color.

5. Limit Use to Important Elements: Liquid Glass should be used for the most important elements of your app, such as key controls and navigation, to maintain a distinct functional layer.

6. Adapt Layouts: Extend your content edge to edge and adapt to new control sizes by auditing for hard-coded control heights or inflexible layout constraints.

7. Enhance Interactivity: Liquid Glass is designed to be interactive, so consider how controls can fluidly morph and respond to user interactions, enhancing the overall user experience.

For more detailed guidance, you can refer to the sessions like Build a UIKit app with the new design and Build an AppKit app with the new design which provide insights into adopting Liquid Glass in UIKit and AppKit apps, respectively.
