How to detect if iOS Wifi hardware is ON swift 3

Question

I'm trying to check if the WIFI hardware is on. I don't care if it is connected to internet or not. I just need to know if in the config the wifi is on. I need this because I will be using the GPS and I want to assure that I get the best accuracy.

Answer 1

enum ReachabilityType: CustomStringConvertible {
    case wwan
    case wiFi
    var description: String {
        switch self {
        case .wwan: return "WWAN"
        case .wiFi: return "WiFi"
        }
    }
}
