[Problem Record] Unity packaging iOS real machine crashes, error Error loading ***.app/Frameworks/UnityFramework.framework/UnityFramework

Error reported:

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'

The problem occurs in AdServices' not found and the AdServices.framework file is missing.

iOS 13.6 crashes, iOS 15.1/15.5 works normally

reason:

You need to manually add libraries/frameworks to the connected iOS SDK, among which AdServices is optional and only supports iOS versions 14.3 and above.

The actual setting is required, which causes exceptions on lower versions of iOS.

solve:

Make AdServices.framework optional:

Method 1: Directly modify the XCode project and change Required to Optional

Method 2: Post-processing after Unity packaging, change false to true

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

        string projPath = PBXProject.GetPBXProjectPath(projectPath);
        PBXProject project = new PBXProject();
        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);
