Track cellular data usage with fast

Question

Is there a way to track the cellular data used by a device in swift? Is there any api? I am trying to achieve something like this

Updated to Swift 4, you can use this simple extension. To track device cell usage and Wi-Fi.

extension SystemDataUsage { public static var wifiCompelete: UInt64 { return SystemDataUsage.getDataUsage().wifiSent + SystemDataUsage.getDataUsage().wifiReceived } public static var wwanCompelete: UInt64 { return SystemDataUsage.getDataUsage().wirelessWanDataSent + SystemDataUsage.getDataUsage().wirelessWanDataReceived } } class SystemDataUsage { private static let wwanInterfacePrefix = "pdp_ip" private static let wifiInterfacePrefix = "en" class func getDataUsage() -> DataUsageInfo { var ifaddr: UnsafeMutablePointer<ifaddrs>? var dataUsageInfo = DataUsageInfo() guard getifaddrs(&ifaddr) == 0 else { return dataUsageInfo } while let addr = ifaddr { guard let info = getDataUsageInfo(from: addr) else { ifaddr = addr.pointee.ifa_next continue } dataUsageInfo.updateInfoByAdding(info) ifaddr = addr.pointee.ifa_next } freeifaddrs(ifaddr) return dataUsageInfo } private class func getDataUsageInfo(from infoPointer: UnsafeMutablePointer<ifaddrs>) -> DataUsageInfo? { let pointer = infoPointer let name: String! = String(cString: pointer.pointee.ifa_name) let addr = pointer.pointee.ifa_addr.pointee guard addr.sa_family == UInt8(AF_LINK) else { return nil } return dataUsageInfo(from: pointer, name: name) } private class func dataUsageInfo(from pointer: UnsafeMutablePointer<ifaddrs>, name: String) -> DataUsageInfo { var networkData: UnsafeMutablePointer<if_data>? var dataUsageInfo = DataUsageInfo() if name.hasPrefix(wifiInterfacePrefix) { networkData = unsafeBitCast(pointer.pointee.ifa_data, to: UnsafeMutablePointer<if_data>.self) if let data = networkData { dataUsageInfo.wifiSent += UInt64(data.pointee.ifi_obytes) dataUsageInfo.wifiReceived += UInt64(data.pointee.ifi_ibytes) } } else if name.hasPrefix(wwanInterfacePrefix) { networkData = unsafeBitCast(pointer.pointee.ifa_data, to: UnsafeMutablePointer<if_data>.self) if let data = networkData { dataUsageInfo.wirelessWanDataSent += UInt64(data.pointee.ifi_obytes) dataUsageInfo.wirelessWanDataReceived += UInt64(data.pointee.ifi_ibytes) } } return dataUsageInfo } } struct DataUsageInfo { var wifiReceived: UInt64 = 0 var wifiSent: UInt64 = 0 var wirelessWanDataReceived: UInt64 = 0 var wirelessWanDataSent: UInt64 = 0 mutating func updateInfoByAdding(_ info: DataUsageInfo) { wifiSent += info.wifiSent wifiReceived += info.wifiReceived wirelessWanDataSent += info.wirelessWanDataSent wirelessWanDataReceived += info.wirelessWanDataReceived } } 

You can use it like: SystemDataUsage.wifiCompelete
