In our team, every time there was a bug in Safari, it was something awfully wrong in our code that just happened to work on Chrome/FF for mysterious reasons. I never had a problem on Safari with standard quality code.
This is being far too kind to Safari. They were the ones who unilaterally decided that 7 days is sufficient time to clear out localStorage and IndexedDB.
While the File System Access API is still being developed, I'm not holding my breath for it to appear on iOS. To be fair, it isn't supported yet on mobile Chrome (for Android obviously), but I expect it will be added quickly after the v1 of the API is finalized. I expect it will either never appear on iOS or it will take 5+ years from now...
Why is it that iOS Safari was the first to support date inputs back in 2007, but desktop Safari, using the same engine, still doesn’t support it some 14 years later?
Additionally, found this recent post going into why Safari is hot garbage. https://infrequently.org/2021/04/progress-delayed/
