The package has a minimum target iOS 15 but all public functions are available in iOS 16+, which someone discovers after the package installation.

Thanks to #1 it allows HFlow/VFlow to be conditionally included in projects that support older deployment targets. The Layout protocol was introduced in iOS 16. Theoretically, it’s possible to back-deploy some of the functionality with GeometryReaders but I did not look into it yet.

I would greatly appreciate if this can be supported from iOS 15.

Bumped to iOS 16, macOS 13, tvOS 16, watchOS 9 in release 2.0.0
