I've a iOT companion app, in which I'll connect to iOT's Wi-Fi and then communicate the device with APIs,
for the above functionality we needed local network permission So we enabled neccessary keys in info.plist and at the time of App Launch we trigger local network permission using the following code
info.plist
<string>This app needs local network access permission to connect with your iOT device and customize its settings</string>
<key>NSBonjourServices</key>
<array>
<string>_network-perm._tcp</string>
<string>_network-perm._udp</string>
</array>

I want to satisfy this following cases but it's not working as expected
# Case1 Working
App launches --> trigger permission using above code --> user granted permission --> connect to iOT's Wi-Fi using app --> Communicate via Local API ---> should return success response
# Case2 Not working
App launches --> trigger permission using above code --> user denied permission --> connect to iOT's Wi-Fi using app --> Communicate via Local API ---> should throw an error
I double checked the permission status in the app settings there also showing disabled state
In my case case 2 is also return success, even though user denied the permission I got success response. I wonder why this happens
the same above 2 cases working as expected in iOS 17.x versions
