iOS build crashes when trying to access WebCamTexture.videoRotationAngle

 using UnityEngine;
 using System.Collections;
 
 public class SelfieScreen : MonoBehaviour {
     
     private CanvasRenderer m_renderer;
     private WebCamTexture m_selfie;
     private WebCamDevice [] m_webCamDevices;
     private Quaternion m_baseRotation;
     private Material m_material;
 
     void Start() {
         m_baseRotation = transform.rotation;
         m_renderer = GetComponent<CanvasRenderer>();
         m_material = m_renderer.GetMaterial();
         m_webCamDevices = WebCamTexture.devices;
         m_selfie = new WebCamTexture(m_webCamDevices[m_webCamDevices.Length - 1].name, Screen.width, Screen.height);
         m_renderer.SetMaterial(m_renderer.GetMaterial(), m_selfie);
         Logger.Log(m_selfie.videoRotationAngle);
         Logger.Log(m_selfie.videoVerticallyMirrored);
         m_selfie.Play();
     }
 
     void Update() {
         m_renderer.SetMaterial(m_renderer.GetMaterial(), m_selfie);
     }
 }

This code works well when i build it on unity editor. But when i build this to iphone it crashes on launch. If I comment out the line that tries to print the videoRotationAngle then then build works on iphone. Anyone has experienced this?
