Is it mandatory for all developers to migrate to Xcode 26 starting from April 28, 2026?
What happens if a developer submits or distributes a build created using Xcode 16 after April 28, 2026? Will it still be accepted or supported?
Our app is distributed only via an internal company portal (not through the App Store). In this case, are we still required to build and distribute the app using Xcode 26 after April 28, 2026?
If a hotfix is required before our next planned release (July 2026), how safe is it to use the UIDesignRequiresCompatibility flag as a temporary solution, assuming Xcode 26 becomes mandatory? Are there any risks or limitations associated with this approach?
What are the potential issues if a team continues development on Xcode 16 while others have migrated to Xcode 26? For example, could there be compatibility, build, or integration challenges in such a mixed environment?
If the UIDesignRequiresCompatibility flag is used as a temporary workaround, what would be the impact if Apple later removes support for this flag, especially with newer iOS versions (e.g., iOS 26+)?
