I want to know the structure how to send restrict information from parent to child. When parent sets restriction on parent's device, that information is reflected on the child's device and the child is restricted from using the app and device. I want to know how the restrictions set on the parent's device are transmitted to the child's device. Also, I want to know how to do it. I could even call requestAuthorization and succeed. Does anyone know this?

To shield applications, we have to pass ApplicationTokens to DeviceAcvivityMonitorExtension. But I don't know the way. I tried to pass it by using NSUserDefaults. However, it didn't work because ApplicationToken isn't encodable. So I can't save it in UserDefaults Does anyone knows the way to pass ApplicationTokens to the Extension or another way to shield apps?
