It sounds like they were testing with iOS 12? In practice that has fallen out of use and doesn't need to be supported any more. Yes, a bunch of problems are to do with Safari specifically, but if you target relatively modern versions only (iOS 16+ is pretty reasonable IMO) it'll save a lot of pain.
Yeah, supporting iOS 12 in 2025 is odd. I was investigating browser support levels just recently for a library and also settled on iOS 16 as a reasonable level.
For reference, iOS 12.x and below are used 0.33% globally https://browsersl.ist/#q=safari+%3C+13+or+ios+%3C+13. Selecting iOS 16 would still exclude less than 1% globally https://browsersl.ist/#q=safari+%3C+16+or+ios+%3C+16. In both cases the vast majority would be older iOS which is unfortunate because I assume they're on older devices with no upgrade path, but you have to decide on the transpile/polyfill cutoff at some point and browser support has an extremely long tail.
I have to support iOS 16. In terms of browser specific bugs that I have to deal with I'd say about 80-90% of what I encounter is Safari specific. Of that another 80% only affects iOS and of that like 2/3 are fixed in more current versions.
