Exercise 2: Where to Test Three Features — Possible Solution
=============================================================

TASK
For a photo-capture feature, a map with location, and a list screen, say
where you would test each first and last, and why.

ANSWER
- Photo capture: first in the Simulator only for the layout around it
  (buttons, previews), because the camera was listed as not simulated and a
  forum source says it is unsupported. Last, and most importantly, on a real
  device, since only a device can show the real capture behavior.
- Map with location: first in the Simulator, because location can be
  simulated with Debug -> Location presets (including a custom latitude and
  longitude). Last on a real device to check real location behavior.
- List screen: first in the Simulator or SwiftUI Previews, since it is a
  layout and logic problem. Last on a real device, in a Release build, if
  scrolling performance matters, because the Simulator is not accurate for
  performance.

CAUTION
The camera and location claims come from a 2018 archived guide and a forum
thread. Confirm the current behavior in your Xcode version.
