Exercise 1: What the 2018 Guide Says the Simulator Could Not Do — Possible Solution
====================================================================================

TASK
List four things the Simulator did not simulate and explain why the guide's
date should make you cautious.

ANSWER
Four items from Apple's archived guide:
1. Motion (accelerometer and gyroscope)
2. Audio and video input (camera and microphone)
3. The proximity sensor
4. The barometer
(The ambient light sensor is a fifth.)

WHY THE DATE MATTERS
The guide was retired and deprecated in Xcode 9 and last updated on 15
February 2018. Simulators have changed since. For example, a more recent
tutorial reports that Xcode 14 simulators on macOS 13 can receive remote
push notifications for debug builds against the sandbox, which the 2018
guide listed as missing. So the list shows the kinds of limits to expect,
not the present ones.

CHECK
The four items and the date come from the guide; the push notification
change comes from a tutorial, not from Apple's current documentation.
