### Examples

```csharp
using UnityEngine;
using UnityEditor;
using System.IO;
using UnityEditor.Callbacks;
using UnityEditor.iOS.Xcode;
using System.Linq;

public class Sample_GetRealPathsOfAllFiles  
{
    [PostProcessBuild]
    public static void OnPostprocessBuild(BuildTarget buildTarget, string pathToBuiltProject)
    {

        // Stop processing if build target is not iOS
        if (buildTarget != BuildTarget.iOS)
            return;

        // Initialize PBXProject
        string projectPath = PBXProject.GetPBXProjectPath(pathToBuiltProject);
        PBXProject pbxProject = new PBXProject();
        pbxProject.ReadFromFile(projectPath);

        // Get real paths of all project files that use relative location
        string[] filePaths = pbxProject.GetRealPathsOfAllFiles(PBXSourceTree.Source).ToArray();

        // Print all paths to console for debugging
        foreach (string path in filePaths)
        {
            Debug.Log(path);
        }
