It’s possible Apple independently arrived at a design for how to present iOS notifications that just happened to resemble growl in every way... but it’s not likely. Growl was so pervasive before macOS notifications that it’s inconceivable to me that developers at Apple weren’t presenting it as a proven model.
Uh huh. This is ignoring that notifications were present in webOS, Android, Windows 7, and so on. Or were those able to independently arrive at the exact same design of a toast popup, and Apple uniquely owes the provenance of their toast popup to Growl?
I was only saying that it seems pretty likely Apple took inspiration from Growl. Not that they didn’t take inspiration from other prior art, or that Growl didn’t either. They’ve taken similar inspiration from other things on their own platform even where there were multiple inspiration sources available. Spotlight took design direction from Quicksilver even though Enso existed. From Mac OS 8 (or was it 9?) through most of the OS X/macOS span, it took inspiration or cues from WindowShade even though a zillion other minimization styles existed. They literally bought CoverFlow even though a ton of other presentational equivalents existed. It’s not that these ideas don’t flow around everywhere. I was just observing that they likely observed what was already at home on their platform.
