SPM Xcode project generation seems to be deprecated, how do we test new binary dependencies feature?

SPM support for Binary Dependencies has been implemented in Swift 5.3, and I would like to try it out now. But I noticed that there have been no updates to the Xcode project file generator to support this feature. That makes sense since Xcode/SPM integration is now built in to Xcode.

But how do I test Binary Dependencies in Xcode, since Xcode hasn't been updated to support the new SPM feature yet?

I noticed there has been new use of PIF files for this feature. Does that make this change compatible with any currently released versions of Xcode?

Basically same answer as here, there isn't a way to use binary dependencies support in Xcode at the moment.
