Dear Apple Developer Support,
I am developing and maintaining an iOS application.
In iOS 26, we understand that setting UIDesignRequiresCompatibility to true in the Info.plist file allows an app to opt out of the Liquid Glass design.
However, we also understand that during WWDC25 Platforms State of the Union, Apple stated:
"We intend this option to be removed in the next major release."
We would appreciate clarification on the following points.
Questions
Should the phrase "next major release" be interpreted as iOS 27?
Is it currently Apple's plan to make UIDesignRequiresCompatibility unavailable or remove it in iOS 27? Or is the statement above only an intended direction, with the actual removal schedule still subject to change? If there is any publicly shareable information regarding the future availability or deprecation timeline of UIDesignRequiresCompatibility, could you please provide it?
Background
We develop and maintain a business application that contains a large number of custom screens and UI components.
Adapting the entire application to the Liquid Glass design system will require significant design review, implementation effort, and testing. As a result, the future availability of UIDesignRequiresCompatibility is a critical factor in our development planning and resource allocation.
For this reason, we would greatly appreciate any guidance you can provide regarding Apple's current plans for this compatibility option.
Thank you for your time and assistance.
Best regards, Toshiyuki
