Swift 3:

If any one is looking for a way to get device token in Swift 3. Use the below modified snippet.

    let characterSet: CharacterSet = CharacterSet( charactersIn: "<>" )

    let deviceTokenString: String = (deviceToken.description as NSString)
        .trimmingCharacters(in: characterSet as CharacterSet)
        .replacingOccurrences(of: " ", with: "")
        .uppercased()

    print(deviceTokenString)
