I am trying to reproduce the crash reported by our CI.
The app uses [NEHotspotConfigurationManager getConfiguredSSIDsWithCompletionHandler:] API to manage SSID configurations and it works fine on device and does not cause any issues when I try to reproduce it in Sim locally.
However, the crash report says that the crash does occur from time to time.
Below is the snipped of the crash report:
I'm thinking maybe it is an Entitlement issue, since the API usage requires special entitlement. Does XPC call stack suggest this?
In general, this API does not make much sense for the Sim, so I'm thinking about mocking it for that particular case under the conditions
But, I still want to figure out the cause.
