Card Conversation Messages not showing up in iOS SDK conversation

Content

Hi,

I'm using Card Conversation Messages for creating a Who Is Who. When I try it out on the test channel, it works fine. When I try it in an iOS app using the iOS SDK it doesn't show up. See image.

I also included the custom code I use for creating the Card Conversation Message.

Does anyone know what the cause (and solution) for this might be?

Kind regards,

Lukas

if(hits.length > 0) {
            for(var i = 0; i < hits.length; i++) {
                let card = conversation.MessageModel().cardObject(hits[i].name, 
                    hits[i].departement + " | " + hits[i].info.telephone + " | " + hits[i].info.email,
                    hits[i].info.imageUrl);
