Looking at the git repo (https://github.com/ai-ng/swift), it was made by some web developer, not Vercel. Likely OP (Vercel CEO) just made a mistake posting it as a "Show HN".
I mostly used the Street View app to capture 360° spherical panoramas, offline, on-device.
Now that Google has killed the app, I can’t capture those photos! The app worked fine a month ago, why not let me use it, as it worked offline‽
No one seems to be talking about this issue.
I haven’t found suitable replacement apps to capture photospheres on a (i)Phone. The suggested Street View Studio doesn’t let you capture Photo Spheres!
