Core Haptics Unity Errors In Xcode

I am trying to get the Apple Core Haptics plug-in to work with Unity but am having issues when I try to build the project.

I created a completely blank project with just the Core and CoreHaptics plug-ins installed. I then put in a single script (below) which is a replication of the script shared in the WWDC22 video on this subject.

Then when I try to build and run that project I get a series of “Undefined symbol:” errors in Xcode. These effect the CoreHaptics, UIFeedbackGenerator frameworks.

If I remove the script and just build an empty project with Core and CoreHaptics installed the build runs successfully. What am I doing wrong or missing that is causing these errors?

using Apple.CoreHaptics;

using System.Collections;

using UnityEngine;

public class Haptics : MonoBehaviour
{
    private CHHapticEngine _hapticEngine;
    private CHHapticPatternPlayer _hapticPlayer;
    [SerializeField] private AHAPAsset _hapticAsset;

    private void PrepareHaptics()
    {
        _hapticEngine = new CHHapticEngine();
        _hapticEngine.Start();
        _hapticPlayer = _hapticEngine.MakePlayer(_hapticAsset.GetPattern());
    }
    private void Play()
    {
    _hapticPlayer.Start();
}

}
