Swift 6 introduces several new features and improvements, including a new language mode that enhances data race safety. However, the context provided does not specifically address the compatibility of Swift 6 with older iOS devices.

From the information available, we know that Swift 6 can be adopted incrementally, module by module, and it is designed to be source-compatible with previous versions of Swift, which should help in maintaining compatibility with existing codebases. This means that while the new language features and improvements are available, you can choose when to adopt them, potentially easing the transition for apps running on older devices.

For more detailed information on migrating to Swift 6 and ensuring compatibility, you might want to check out the session Migrate your app to Swift 6 (06:20).
