Does structured concurrently require iOS 15?

I would like to know what the earliest deployment target I can use if I use the structured concurrency syntax in my app.

The new swift concurrency features do require iOS 15.

From the release notes.

Swift Concurrency requires a deployment target of macOS 12, iOS 15, tvOS 15, and watchOS 8 or newer. 

Does structured concurrently require iOS 15?
