```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The position at which to insert the new build phase. If it's higher than the total number of build phases, the new phase is added at the end.**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): The GUID of the target, such as the one returned by [PBXProject.TargetGuidByName](/engine/6000.6/script-reference/unityeditor/ios/xcode/pbxproject/targetguidbyname.md).**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): The name of the phase.**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): The shell path.**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): The subfolder spec. The following usages are known:- `10` for embedding frameworks.
- `13` for embedding app extension content.
- `16` for embedding watch content.

### Returns

| Type                                                           | Description                        |
| -------------------------------------------------------------- | ---------------------------------- |
| [string](https://learn.microsoft.com/dotnet/api/system.string) | Returns the GUID of the new phase. |

### Remarks

The build phase is inserted at the specified position. You can query all the defined build phases using [PBXProject.GetAllBuildPhasesForTarget](/engine/6000.6/script-reference/unityeditor/ios/xcode/pbxproject/getallbuildphasesfortarget.md).

### Examples

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

public class Sample_InsertCopyFilesBuildPhase  
{
    [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 main target GUID  
        string mainTargetGuid = pbxProject.GetUnityMainTargetGuid();

        // Insert a Copy Files Build Phase to the main target as first custom build phase (index 0)
        pbxProject.InsertCopyFilesBuildPhase(0, mainTargetGuid, "ExamplePhase", "path/to/file", "10");

        // Apply changes to the pbxproj file
        pbxProject.WriteToFile(projectPath);
    }
}
