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

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

You can use this command to get address `ipconfig getifaddr en0`. If you call wrong `en` this command revert `null` — Artem Dorodovskyi, Apr 26 '18 at 09:41
Yes but i still don't know if it's the ethernet or wlan address. — Marie Dm, Apr 26 '18 at 09:45
I found the command `networksetup -listnetworkserviceorder` that print your Hardware Port(wi-fi, Thunderbolt Bridge) and Device(en0, en1, bridge1) . I hope that is what you need. — Artem Dorodovskyi, Apr 26 '18 at 09:56
Working from my terminal but not from the Mac app, getting "launch path not accessible", might be cause it's sandboxed. — Marie Dm, Apr 26 '18 at 10:01
@MarieDm Please don't add a solution in your question :) Instead add it as an answer. — geisterfurz007, Apr 30 '18 at 10:13

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

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"]
