Seems like NetInfo.isConnected.fetch() bug in iOS has been resolved in RN 0.55.x

[adam-s]

On the other hand it seems that the work around for the bug (facebook/react-native#8615) using the attached listener now waits for connection event to happen before broadcasting. So the function is run but doesn't resolve. It waits for an event to happen then resolves.

Because of this, the checkInternetConnection() function doesn't work in RN 0.55.x for iOS.

So to confirm is this library currently broken on iOS?

This is my first time using it and have been pulling my hair out all day trying to get this going via the simulator and a device. Then I tested on an Android device / simulator and everything was working as expected. Are there any work arounds to get this going on iOS?

Update: The stack overflow answer for this post is working for me (i.e. in terms of testing connectivity state and subsequent changes to that state).

This has been resolved probably by this commit: facebook/react-native@36199d3

Resolved or not, here's a module I made to make sure we never see that issue again:

I've tested the new major version 4.0.0 with RN 0.55.x and 0.57.x and verified that checkInternetConnection() works correctly.

However, I've noticed that the offline behaviour on iOS simulators is not reliable. I've updated this section on the docs to reflect that.

Could you please give it a try to v.4.0.0 and let me know? In case you are coming from v3, follow the release notes to upgrade.

Thanks!
