They pass in an iPhone SE (3rd gen) simulator.

That is because our simualtor being used to run testing for API-tests on iOS is an iPhone SE (3rd Gen). We want to move to an iPhone 12 to match the testing model for layout-tests.

After you have chosen your booted simulator it will choose to run on that simulated device, and not the one that we have set for our testing. 1957464 3 jenner 2023-05-23 15:49:02 -0700 *** Bug 257231 has been marked as a duplicate of this bug. *** 1957758 4 jenner 2023-05-24 17:10:03 -0700 *** This bug has been marked as a duplicate of bug 257235 ***
