Answer 1

Reachability not Notification reason is,

USB cable connecting with XCode debug mode.

(But ios8 version device is no problem, only ios12 version device have a problem) . . . . .

But correct operation to Notification, disconnect USB cable without XCode,

Answer 2

In iOS 12 Reachability feature is off by default. You must manually enable it on your iPhone by venturing into Settings → General → Accessibility → Reachability.
