【问题记录】Unity打包iOS真机闪退，报错Error loading ***.app/Frameworks/UnityFramework.framework/UnityFramework_unity ios闪退

报错：

Error loading /var/containers/Bundle/Application/61CD0810-9E62-452B-8129-3DAC706B56C5/HarvestBumpers.app/Frameworks/UnityFramework.framework/UnityFramework: dlopen(/var/containers/Bundle/Application/61CD0810-9E62-452B-8129-3DAC706B56C5/HarvestBumpers.app/Frameworks/UnityFramework.framework/UnityFramework, 0x0109): dependent dylib '/System/Library/Frameworks/AdServices.framework/AdServices' not found for '/private/var/containers/Bundle/Application/61CD0810-9E62-452B-8129-3DAC706B56C5/HarvestBumpers.app/Frameworks/UnityFramework.framework/UnityFramework'

问题出现在AdServices' not found，缺少AdServices.framework文件

iOS 13.6闪退，iOS 15.1/15.5正常

原因：

接入的iOS SDK中需要手动添加库/框架，其中AdServices是可选的，仅支持14.3及以上版本iOS。

实际设置为了必选的，导致低版本iOS异常。

解决：

将AdServices.framework设置为可选项：

方式一：直接修改XCode工程，将Required改为Optional

方式二：Unity打包后处理，false改为true

project.AddFrameworkToProject(frameGuid,"AdServices.framework",true)

        project.ReadFromString(File.ReadAllText(projPath));
 
        string frameGuid = project.GetUnityFrameworkTargetGuid();
 
        //True if the framework is optional (i.e. weakly linked), false if the framework is required.
        project.AddFrameworkToProject(frameGuid,"AdServices.framework",true);
