Mac OS terminal command How to differentiate wlan from ethernet address? - macos

Question

I'm making a mac os app. I'm trying to get the ethernet and wlan addresses. I know these are en0 and en1 addresses but depending on devices, en0 can be the ethernet or the wlan one. Is there a way to know which one it is?
So far I'm using this which gets me both addresses but don't differentiate them:
let task=Process.init()
task.launchPath="/sbin/ifconfig"
task.arguments=["en0"] //or en1
let pipe=Pipe()
task.standardOutput=pipe
task.launch()
let data=pipe.fileHandleForReading.readDataToEndOfFile()
guard let stringResult=String(data: data, encoding: String.Encoding.utf8) as NSString? else{wlanFailed();return}
print("en0:", stringResult)
EDIT
So now I'm trying to run this command networksetup -listnetworkserviceorder which works from my terminal.
But I don't know how to make it work from my Mac app. For example, with this:
let task=Process.init()
task.launchPath="/sbin/networksetup"
task.arguments=["-listnetworkserviceorder"]
I get:
launch path not accessible

Answer 1

These are some commands that help to match the interface with the hardware name:
networksetup -listallhardwareports
networksetup -listnetworkserviceorder
system_profiler SPNetworkDataType
scutil <<< "list" | grep -i airport

Answer 2

Thanks #artem-dorodovskiy and #nbari for giving me the command line.
I found how to write it thanks to this SOF answer.
let task=Process.init()
task.launchPath="/usr/bin/env"
task.arguments=["networksetup", "-listnetworkserviceorder"]
