If you don't change the build number in unity, the build won't push to AppStoreConect.
Put this script in the editor folder.
Then, in your unity dashboard config for cloud build. In advanced options, set the following:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
public class AutoIncrementVersionCodeInCloudBuild : MonoBehaviour
{
#if UNITY_CLOUD_BUILD
public static void PreExport(UnityEngine.CloudBuild.BuildManifestObject manifest)
{
string buildNumber = manifest.GetValue("buildNumber", "0");
Debug.LogWarning("Setting build number to " + buildNumber);
PlayerSettings.Android.bundleVersionCode = int.Parse(buildNumber);
PlayerSettings.iOS.buildNumber = buildNumber;
}
#endif
}
