I have been reading about DTO (Data transfer object ) since few days. I understood concept that drives it. The concept is to make the domain object decoupled from external APIs or storage objects, by having datasource model. Certainly this will ensure a good separation of concern and make the program somewhat secure from the future change in the data model. But is that the only reason for using it? I see it adds a lot of extra code for something which may happen in future. Has anyone ever used DTOs in there iOS project and have it benefited them? Thanks in advance

I am woking on an application which has a built in browser type of feature. The user can browse any url on that webview. We know that iOS mandates to add different privacy usage description for accessing different user sensitive informations such as NSCameraUsageDescription, NSMicrophoneUsageDescription etc. As I am not sure which website an user will browse & what user sensitive datas those websites will ask, how can I anticipate and add that usage description key/value in the plist? Is there any better way to handle this situation? Thanks in advance
