CoreTelephony.framework could provide you such details:

Objective-C

CTTelephonyNetworkInfo *telephonyInfo = [[CTTelephonyNetworkInfo alloc] init];
NSString *technologyString = telephonyInfo.currentRadioAccessTechnology;

if ([technologyString isEqualToString:CTRadioAccessTechnologyLTE]) {
    // LTE (4G)
} else if([technologyString isEqualToString:CTRadioAccessTechnologyWCDMA]){
    // 3G
} else if([technologyString isEqualToString:CTRadioAccessTechnologyEdge]) {
    // EDGE (2G)
}

Swift

import CoreTelephony

let telefonyInfo = CTTelephonyNetworkInfo()
if let radioAccessTechnology = telefonyInfo.currentRadioAccessTechnology{
  switch radioAccessTechnology{
  case CTRadioAccessTechnologyLTE: print("LTE (4G)")
  case CTRadioAccessTechnologyWCDMA: print("3G")
  case CTRadioAccessTechnologyEdge: print("EDGE (2G)")
  default: print("Other")
  }
}
