Identify the test device for Admob

Question

I use the code below:

let request : GADRequest = GADRequest ()

request.testDevices = ["xxxxxxx",kGADSimulatorID]

But I am getting the below warning:

'testDevices' is deprecated: Use GADMobileAds.sharedInstance.requestConfiguration.testDeviceIdentifiers.

Do I use a syntax to remove the warning?

This is a modification to 10623169's answer.

To get a valid ID, for the current device, that can be set in "testDevices", get the MD5 of this: UIDevice.current.identifierForVendor?.uuidString

The asIdentifier value can be completely invalid if the user hasn't given permission for tracking. But the UIDevice.current.identifierForVendor is a valid UUID for the app, that will persist across launches (but perhaps not if you delete the app and reinstall).
