SwiftUI Network Reachability with NWPathMonitor and Observation

Knowing if the device is online isn't enough — you also need to know how it's connected.

What this video covers:

• Setting up NWPathMonitor for network monitoring
• Detecting connection type: Wi‑Fi, cellular, wired, or none
• Identifying expensive networks (cellular, personal hotspot)
• Reacting to changes using @Observable and @Environment
• Showing user‑friendly messages for different connection states

Real example: A video streaming app that warns users when on cellular, or a download manager that pauses on expensive networks.
