title: Determine network type in iOS 14 Swift 5 without Thirdparty Library
body: <p><code>CTTelephonyNetworkInfo.currentRadioAccessTechnology</code> is deprecated in iOS 12. so is there any api to get the network type?. we can use NWPathMonitor to know wifi, cellular, ethernet type but not 3g,4g,5g etc. Is there any complete solution for this.</p>
