iOS14 - Local Network permission support

[vasyl-i]

Feature request

Support for Local Network permission needed (iOS14)

Why it is needed

With iOS 14 user may disallow Local Network permission for mobile app, which will deny access for app to local devices.
https://developer.apple.com/videos/play/wwdc2020/10110/

Possible implementation

Should be used like something like this:

    Permissions.getPermissionStatus('localNetwork').then((r) => {
        if (r === 'authorized') {
           // Do something
        } else if (r === 'undetermined') {
          Permissions.requestPermission('localNetwork').then((response) => {
              if (response === 'authorized') {
                           // Do something
              }
              if (response === 'denied') {
               // Notify user about Local Network permission denied, advice user to turn on permission
               }
            });
        } else {
               // Notify user about Local Network permission denied, advice user to turn on permission
        }
      });

@vahutson I'm not sure this is a requestable permission? I can't find any documentation about it on https://developer.apple.com/documentation/

@fernandesrenan Not really:

I see this question has been asked on the forums already, and there is no API.

This means that no native API no feature on react-native-permissions?

@fernandesrenan Totally. We are not wizards, Apple has to do its job.

[voulgarakis]

is there a way to request user to allow Local Network permission in iOS 14?

Same issue here

[mikehardy]

@geroale doesn't look like an "issue" at this point, based on @jimji1005 comment it looks like it needs someone to implement it. Do you have PR you could propose?

[MarinaAmy]

@vahutson resolve ?

It seems that still there is not native api to trigger at this point (end of 2021) so this is not an issue can be handled
directly here.
But.. There is a hack around this.

For popping up the permission prompt:
send a dummy request on your network which will prompt the pop.

Can be handled "manually" or it can be implemented as an api in react-native-permissions as an api so for the
end user it will handle as all other library permission api's
(Its a bit of a nasty hack, so guess its for the admins to decide)

Checking if Local Network permission is granted:
This sill requite native code, but basically you will need to check the error type on connection fail
and label it as Local Network.
This will, require a PR as it not possible to do "manually" using only JS..

More in depth details about these solutions can be found in this SO answer - link

Personally Im going to write a small native library to perform these 2 hacks..

Can share the code for a PR to be added to this library if anyone is interested (I do write it in Swift though)

PS: All discussions I found about this issue on the native side are at the end of 2020, so maybe an api for these was added by now, if so I could not find such a thing.

Hope this helps
