What is the scope of this framework? Creating UI's with prior jetpack compose knowledge has been a breeze, but say I want to read user location (i.e. a macos native api), how would I do that? Is it out of the scope? Or should I look for some jvm library which provides that?

Yes and yes.

If I might ask, how does one even do that? Say I want the macos location, should I look for a C api, and expose that to java via JNI? What about swift? Is there a mechanism to bridge those to jvm world?

Yes, or use JNA or equivalent. But for that thing specifically there is

System.getProperty("user.home")

I think he meant physical, geographical, location. But who knows…

Ah you're right, that's a more likely interpretation.

yea gps location, i.e. some native api
