[iOS][Xcode][Unity 2019.4.21f1] GoogleService-Info.plist not include in your build

How to solve the problem

• Directly copy the file GoogleService-Info.plist during xcode build through PostProcessBuild
• Place BuildPostProcessorInfo.cs anywhere in your Unity project

#if UNITY_EDITOR && UNITY_IOS
using System.IO;
using UnityEditor;
using UnityEditor.Callbacks;
using UnityEditor.iOS.Xcode;

public class BuildPostProcessorInfo
{
        [PostProcessBuild]
	public static void OnPostProcessBuildAddFirebaseFile(BuildTarget buildTarget, string pathToBuiltProject)
	{
		if (buildTarget == BuildTarget.iOS)
		{
			// Go get pbxproj file
			string projPath = pathToBuiltProject + "/Unity-iPhone.xcodeproj/project.pbxproj";
			// PBXProject class represents a project build settings file,
			// here is how to read that in.
			PBXProject proj = new PBXProject();
			proj.ReadFromFile(projPath);
			// Copy plist from the project folder to the build folder
			proj.AddFileToBuild(proj.GetUnityMainTargetGuid(), proj.AddFile("GoogleService-Info.plist", "GoogleService-Info.plist"));
			// Write PBXProject object back to the file
			proj.WriteToFile(projPath);
		}
	}
}
#endif
