Clarification on UIDesignRequiresCompatibility Key and Liquid Glass Adoption

Dear Apple Developer Relations Team,

We are currently reviewing the documentation for the UIDesignRequiresCompatibility Info.plist key.

In the documentation, there is a warning that states: "Temporarily use this key while reviewing and refining your app’s UI for the design in the latest SDKs."

However, in the adoption guide for Liquid Glass: Adopting Liquid Glass, we did not see any explicit requirement to force adoption of the Liquid Glass design.

We have the Gojek app, which currently uses the UIDesignRequiresCompatibility key. To ensure long-term stability, we would like clarification on the following points:

1. Future Support of the Key:

• Is it safe to continue using the UIDesignRequiresCompatibility key? Can you confirm whether this key will remain supported or if there are plans for it to be deprecated/removed in future iOS versions?

1. Liquid Glass Adoption:

• Our app’s design guidelines do not align with the Liquid Glass style. Can you confirm that adoption of Liquid Glass is not mandatory, and that apps can continue to use their existing custom design guidelines without any restrictions?

1. Compatibility with iOS 26:

• Are there any required changes we need to make to our existing views to ensure that the UI will continue to render as it does today on iOS 26 and beyond?

We want to make sure we provide the best user experience while remaining compliant with Apple’s guidelines. Your clarification would help us plan our design and development roadmap accordingly.

Thank you for your support and guidance.
