How to check if the device is LTE, 3G, HSPA or Wi-Fi?

Is it possible to determine which network is on the device when a user interacts with my application?

Now I have a Reachability class and I can distinguish between Wi-Fi and Cellular, but how to check if Cellular LTE, 3G, HSPA, EDGE?

There is currently no way to distinguish between different types of cellular networks.

See this question for more information.

As in iOS7, cellular connection information is available using CTTelephonyNetworkInfo ():

let info = CTTelephonyNetworkInfo()
print("carrierName": " + "\(info.subscriberCellularProvider?.carrierName ?? "Has not been configured for carrier")")
print("currentRadioAccessTechnology: " + "\(info.currentRadioAccessTechnology ?? "Airplane Mode/No cell connection")")

currentRadioAccessTechnology will display a string describing the type of connection.
