UserBuildSettings.linkTimeOptimization

Description

Use the precompiled and link time optimized (ThinLTO) Unity engine code (libunity.so) for non-development builds.

Use this property for improved runtime performance and reduced memory usage. For more information, refer to the documentation on ThinLTO.

Notes:

• Only supported on Meta Quest. Unity ignores this property on unsupported platforms.
• You can use link time optimized Unity engine code if your project uses IL2CPP scripting backend and Strip Engine Code is disabled. This doesn't affect IL2CPP compilation.

using UnityEditor.Android;
using Unity.Android.Types;

public class Settings
{
    public void Setup()
    {
        UserBuildSettings.linkTimeOptimization = AndroidLinkTimeOptimization.Thin;
    }
}
