Safari or iPhone emulator?

Question

iOS

Got out of trouble with the site on the mobile phone does not display information. The vue application receives data from the backend in about 600ms. Everything is fine in chrome. The question is actually some method to get statistics either from a hardware phone or run an emulator to understand what went wrong. I suspect that either the time is 600 ms or the size is about 90 kilobytes. What do you advise?

Answer 1

MacOS + xCode - and there is an iPhone emulator.
Safari - again, only on apple devices like.
It is quite possible to put on a virtual machine.
