I'm working on ios app with iot, i have following questions regarding: I want to fetch "Battery Temp, Voltage, Current, Percentage, Charging State, Battery Capacity, Charging count, Incoming Calls, UUID, Phone Model, Phone Manufacture in Swift? We have class in objective c - UIDeviceListener, But its comes under IOKit framwork - if you want to submit an app using IOKit framework is risky because I red Apple may not allow that, Then Swift has UIDevice, but its providing limited information, what is alternate solution or workaround for this?
