Check For Internet Connectivity In Swift

Question

I am using Swift 3 and Xcode 8. All the other scripts and stuff online to do this all raise a lot of errors. How would I in a simple way make the app check for an Internet connection when it was launched and if it had one to continue and if it doesn't have a connection to show the user a popup saying so?

I am open to any suggestion.

Answer 1

The easiest way to check for internet connectivity is to use the iOS reachability api.

It's available in the SystemConfiguration module.

Objective-C Reachability Example

A good example of using SCNetworkReachability in swift is found in the stack overflow answer:

I hope this helps! Have a nice day!
