# AddBuildConfig(string)

> Creates a new set of build configurations for all targets in the project.

## Definition

* **Type:** Method
* **Namespace:** [UnityEditor.iOS.Xcode](/engine/6000.5/script-reference/unityeditor/ios/xcode.md)
* **Assembly:** UnityEditor.iOS.Extensions.Xcode

```csharp
public void AddBuildConfig(string name)
```

### Parameters

**** (\[string]\(https\://learn.microsoft.com/dotnet/api/system.string)): The name of the build configuration.

### Remarks

The number and names of the build configurations is a project-wide setting. Each target has the same number of build configurations and the names of these build configurations is the same. The created configurations are initially empty. Care must be taken to fill them with reasonable defaults. The function throws an exception if a build configuration with the given name already exists.

### Examples

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

public class Sample_AddBuildConfig  
{
    [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 GUID for the Main target
        string mainTargetGuid = pbxProject.GetUnityMainTargetGuid();

        // Add the Build Config with a given name
        string configName = "exampleConfig";
        pbxProject.AddBuildConfig(configName);

        // Get the GUID for the config and modify it
        string configGuid = pbxProject.BuildConfigByName(mainTargetGuid, configName);
        pbxProject.AddBuildPropertyForConfig(configGuid, "exampleProperty", "exampleValue");

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