Error using Kundan Augmented SDK

Hi I
am trying to use Kundan SDK by following the tutorial given here. However when I download and open Kundan SDK, I am seeing the following error below:

The type or namespace name Editor’ does not exist in the namespaceUnity’. Are you missing an assembly reference?

The Kundan Tracker.cs can be found here.

How can I solve this?

Either change line 4 from

using Unity.Editor;

to

using UnityEditor;

or remove that line altogether.

I did that. Now it says
cs(172,84): error CS0619: UnityEditor.PlayerSettings.bundleIdentifier' is obsolete: Use PlayerSettings.applicationIdentifier instead (UnityUpgradable) → UnityEditor.PlayerSettings.applicationIdentifier’

KudanTracker.cs(176,90): error CS0619: UnityEditor.PlayerSettings.bundleIdentifier' is obsolete: Use PlayerSettings.applicationIdentifier instead (UnityUpgradable) → UnityEditor.PlayerSettings.applicationIdentifier’

KudanTracker.cs(180,96): error CS0619: UnityEditor.PlayerSettings.bundleIdentifier' is obsolete: Use PlayerSettings.applicationIdentifier instead (UnityUpgradable) → UnityEditor.PlayerSettings.applicationIdentifier’

Should I change PlayerSettings.bundleIdentifier to PlayerSettings.applicationIdentifier??
