There are enough weird divergences to make targeting iOS annoying. Off the top of my head I can recall that Safari PWAs can't get callbacks from pages spawned in a new window. Things have a tendency to fail in strange and unexpected ways.

Worse yet, many people have older iPhones with outdated Safari. You can't tell them to just install another browser, because under the hood Apple mandates that all other browsers are still the same outdated Safari engine.

If you want to track these issues down, you need to invest in an Apple based set up. You can't run Safari outside of the Apple ecosystem to track these issues down. It is bad enough that people are now offering pay as you go Safari instances for testing. Apple gatekeeps, Apple invents problems and developers are stuck with the bag.
