iOS 15 Beta - WiFi network not recognized when enabling Network Protection #153

Closed gorkapernas closed 3 years ago

gorkapernas commented 3 years ago

Description:

On iOS 15 Beta, IVPN 2.4.2 (2), when enabling Network Protection, the available WIFI networks are never recognized. The list of available networks is not shown and when opening the sliding panel in the main screen, the label "No network" is displayed.

@jurajhilje I'm not sure if this is an issue on our app, the problem does not happen iOS 14.

Steps to reproduce:

Install 2.4.2 (2) on an iOS 15 device.
Login.
Connect to install the VPN profile.
Enable Network Protection.
Observe that the list of available networks is not shown, and the label "No network" is displayed in the main screen.

Environment:

OS: iOS 15 Device: iPhone XR IVPN version: 2.4.2 (2)

CNCopyCurrentNetworkInfo used to fetch the current Wi-Fi SSID is deprecated in iOS 15. Looking for possible workarounds.

NEHotspotNetwork.fetchCurrent is currently not working (on my end) on iOS 15.

A bug report has been submitted to Apple. More info here: https://developer.apple.com/forums/thread/670970?page=1#682297022

@gorkapernas I implemented the new API (using NEHotspotNetwork) for fetching WiFi SSID, for all devices running iOS 14+. This way, when Apple fixes NEHotspotNetwork.fetchCurrent API in one of the next iOS 15 versions, our iOS app will already support that fix. For now, we can only test that the new API implemented here works OK on iOS 14 devices. This is available in the latest TestFlight build.

Verified on version 2.5.0(16), iPad 6 iOS 14.6, the app is able to recognise the WIFI SSID after adding the VPN Profile.

Behaviour observed:

When enabling Network Protection after adding the VPN profile, the app takes up to 5 seconds to recognised the network.
If the VPN profile is not yet added, and the user enables/disables Network Protection, the dialog about adding the VPN profile appears, after adding it, the app doesn't recognise the network immediately, but only after the user connects to the VPN (for the first time).

These points have been confirmed as expected.

Issue is FIXED on iOS 15.1 RC / public release.

@gorkapernas Let me know if you can confirm this on your end, using 2.5.0 (17) build.

gorkapernas commented 3 years ago

@jurajhilje confirmed, the issue is fixed on the iOS release candidate 15.1 with the latest beta 2.5.0.
