Instruction

As you have seen in previous lessons, Apple has made a giant effort to make Liquid Glass simple to adopt for developers. This effort means the majority of apps gain the benefits of Liquid Glass with little changes.

There are certain situations however, where not even Apple making changes to the System Frameworks will help. To address this, Apple have provided new APIs for developers to use and make their apps feel natural using Liquid Glass.

The Glass Effect Modifier

The first advanced technique relates to applying Liquid Glass effects to custom views. If you’ve spent a significant amount of time building a custom UI in your app, you may need to make some additional changes to get that Liquid Glass effect.

Glass Effect Containers and Morphing Effects

As you learned in the previous section, SwiftUI controls can apply Liquid Glass in highly configurable ways. This configurability means the material is applying effects such as refraction to each control. Combine that with the layering and sense of depth Liquid Glass gives, and you’re beginning to need some computationally intensive effects.

Cleaning up the UI
