⚠ [ios] handle deprecation of CNCopyCurrentNetworkInfo

[daadu]

• getSSID, getBSSID for ios - should fail because of it
• getSSID is internally used in handling isEnabled, connect, disconnect, those might be affected as well

• CNCopyCurrentNetworkInfo - https://developer.apple.com/reference/systemconfiguration/1614126-cncopycurrentnetworkinfo

The recommended method to replace it is fetchCurrentWithCompletionHandler, this is part of HotspotHelper API which requires "special entitlements", to be requested from Apple manually here.

I have filled a similar issue to network_info_plus plugin at fluttercommunity/plus_plugins#240.

Actions that we can take now:

• remove dependencies of isConnected, connect and disconnect method on getSSID.

Need to be discussed:

• Whether to implement, the fetchCurrentWithCompletionHandler or deprecate (add warning note in README) getSSID and getBSSID for iOS.

This method could take time to be removed (assuming apple gives a breathing period for this, encourage anyone with iOS 14+ phone to test if it is not removed yet and if removed is there any side effect for connect and disconnect methods.). Anyways need to at least find ways to not use getSSID internally for other methods.

PS: I am not a native iOS developer and have not released any production iOS app before.

Looks like fetchCurrentWithCompletionHandler does not require Hotspot Helper entitlement.

+fetchCurrentWithCompletionHandler: does not require the Hotspot Helper entitlement. Unfortunately that fact is not documented officially (r. 74976266). Fortunately, there’s lots of good info about this method in the doc comments in <NetworkExtension/NEHotspotNetwork.h>.

This answer on SO has a possible solution.

Good News: the NetworkInfo instance can provide signal strength, although the value is double from (0.0 to 1.0, lowest to highest), while in Android it is RSSI (which are values <0). Need to do additional calculate (and mention it in README) to bring it to parity.

Additionally we can implement getIP too.

Filed the PR related to it, can someone with iOS 14 device test it?

The fix has landed on pub.dev with v0.3.4.
